Mitigation of aviation’s environmental impact
May 25, 2017

Aviation affects the environment due to aircraft engines emitting noise, particulates, and gases which contribute to climate change[1][2] and global dimming.[3] Despite emission reductions from automobiles and more fuel-efficient (and therefore less polluting) turbofan and turboprop engines, the rapid growth of air travel in recent years contributes to an increase in total pollution attributable to aviation. In the EU, greenhouse gas emissions from aviation increased by 87% between 1990 and 2006.[4]

At present aviation accounts for 2.5% of global CO2 emissions.[5] Due to projected growth in air travel, in the most technologically radical scenarios for having a better than 50% chance of keeping global warming below 2 degrees Celsius, in 2050 aviation will make up 15% of global CO2 emissions. In more conventional scenarios its emissions will exceed the entire global carbon budget before then.[6] This presents governments and the operators of aircraft with a responsibility to reduce the aviation industry’s emissions.
Mitigation of aviation’s environmental impact can be achieved through a variety of measures, the most obvious and arguably the most economical of which is to reduce the fuel burn of the aircraft as this accounts for 28% of an airlines costs. However, there is a wide variety of other options available to minimise aviation’s growing impact upon the environment as are listed below:[7]

Aircraft efficiency Edit

The Boeing 787 Dreamliner promises to provide 20% lower fuel burn than current-generation aircraft.
As stated previously, reducing the direct fuel burn of an aircraft is the most obvious and arguably the most economical way of reducing emissions attributable to aviation. Over the last 40 years, commercial jet airliners have become 70% more fuel efficient and are predicted to be another 25% more fuel efficient by 2025.[7]

The next-generation of aircraft, including the Boeing 787 Dreamliner, Airbus A350 and Bombardier CSeries, are 20% more fuel efficient per passenger kilometre than current generation aircraft. This is primarily achieved through more fuel-efficient engines and lighter airframes & supporting structures made of composite materials but is also achieved through more aerodynamic shapes, winglets, a “one-piece” fuselage and more advanced computer systems for optimising routes and loading of the aircraft. [8]

Route optimization Edit
Currently, air traffic corridors that aircraft are forced to follow place unnecessary detours on an aircraft’s route forcing higher fuel burn and an increase in emissions. An improved Air Traffic Management System with more direct routes and optimized cruising altitudes would allow airlines to reduce their emissions by up to 18%.[7]

In the European Union, a Single European Sky has been proposed for the last 15 years so that there are no overlapping airspace restrictions between countries in the EU and so reduce emissions. As yet, the Single European Sky is still only a plan but progress has been made. If the Single European Sky had been created 15 years ago, 12 million tons of CO2 could have been saved.[7]

Biofuels Edit

British Airways will be using half a million tonnes of waste annually to create biofuels for commercial use from 2014 onwards.
Biofuels are fuels derived from biomass material such as plants and waste. Plant derived biofuels offer large savings in CO2 emissions as they absorb Carbon Dioxide and release it as Oxygen when they grow and so in a life-cycle, emissions can be drastically reduced. A number of airlines have operated biofuel test flights including Virgin Atlantic Airways, which flew with one engine operating on a blend of 20% coconut oil and 80% traditional jet fuel, and Continental Airlines which flew with one engine operating on a blend of 44% Jatropha oil, 6% Algae oil and 50% traditional jet fuel. Other airlines to demonstrate biofuels include Air New Zealand and Japan Airlines.[9]

In the Continental Airlines test, the engine running partly on biofuel burned 46 kg less fuel than the conventionally fuelled engine in 1 and a half hours while producing more thrust from the same volume of fuel. Continental Airlines’ CEO, Larry Kellner, commented “This is a good step forward, an opportunity to really make a difference to the environment” citing jatropha’s 50-80% lower CO2 emissions as opposed to Jet-A1 in its lifecycle.[9]

From 2014 onwards, British Airways, in co-operation with Solena, is going to turn half a million tonnes of waste annually that would normally go to landfill from the City of London into biofuel to be used in the British Airways fleet. Waste derived biofuel produces up to 95% less pollution in its life-cycle and so therefore this measure will reduce emissions by the equivalent of taking 42,000 cars off the road every year.
Airlines and airports are looking at ways of reducing emissions and fuel burn through the use of improved operating procedures. Two of the more common ones in operation are a single-engine taxi to and from the runway and the use of a Continuous Descent Approach, or CDA, which can reduce emissions significantly during the operations in and around an airport.[11] Scandinavian Airlines (SAS) is now operating its Boeing 737 fleet at a slower cruising speed to help reduce emissions by 7-8%.[12]

Emission Trading Scheme Edit
In the EU, aviation will be including the European Emission Trading Scheme from 2012 onwards. The scheme places a cap on the emissions an aircraft operator can emit and forces the operator to either lower emissions through more efficient technology or to buy “Carbon Credits” from other companies who have produced fewer emissions than their cap. It is thought that this will reduce aviation’s net environmental impact.

Aviation produces a number of other pollutants besides carbon dioxide including nitrogen oxides (NOX), particulates, unburned hydrocarbons (UHC) and contrails. A number of methods to reduce the level of these pollutants follows:

Nitrogen oxides (NOX) Edit
Nitrogen oxides have a far stronger impact upon climate change than Carbon Oxides and are produced in small quantities from aircraft engines. Engine designers have worked since the start of the jet age to reduce NOX emissions and the result is ever reducing levels of nitrogen oxide emissions. For example, between 1997 and 2003, NOX emissions from jet engines fell by over 40%.[13]

Particulates Edit
Particulates and smoke were a problem with early jet engines at high power settings but modern engines are designed so that no smoke is produced at any point in the flight.[13]

Unburned hydrocarbons (UHC) Edit

Contrails formed by high altitude aircraft.
Unburned hydrocarbons (UHC) are products of incomplete combustion of fuel and are produced in greater quantities in engines with low pressure gains in the compressors and/or relatively low temperatures in the combustor. As with particulates, UHC has all but been eliminated in modern jet engines through improved design and technology.[13]

Contrails Edit
Aircraft flying at high altitude form condensation trails or contrails in the exhaust plume of their engines. While in the Troposphere these have very little climatic impact. However, jet aircraft cruising in the Stratosphere do create an impact from their contrails, although the extent of the damage to the environment is as yet unknown. Contrails can also trigger the formation of high-altitude Cirrus cloud thus creating a greater climatic effect.[13] A 2015 study found that artificial cloudiness caused by contrail “outbreaks” reduce the difference between daytime and nighttime temperatures. The former are decreased and the latter are increased, in comparison to temperatures the day before and the day after such outbreaks.[14] On days with outbreaks the day/night temperature difference was diminished by about 6F° in the U.S. South and 5F° in the Midwest.[15]

In the three days following the September 11 attacks on the World Trade Center in New York City, when no commercial aircraft flew in the United States, climate scientists measured the daily temperature range over 5000 weather stations across the USA. The results showed a 1 ° Celsius change in the average daily temperature range for those days of the year, thus showing contrails do have a significant impact on climate.[3] Potential ways of reducing the impact of contrails on our climate include reducing the maximum cruising altitude of aircraft so high-altitude contrails can not form. Cruising at lower altitudes would marginally increase flight time and increase fuel consumption by 4%.
One of the by-products of an aircraft’s engine is noise and this has become an increasingly important issue which is being dealt with through many different methods:

Engines Edit
Next-Generation engines are not only more fuel-efficient but also tend to be quieter with Pratt & Whitney’s PurePower PW1000G fitted to the Bombardier CSeries aircraft being 4 times quieter than aircraft currently in service.[17] Engines can also incorporate serrated edges or ‘chevrons’ on the back of the nacelle to reduce noise impact as shown in this picture.[13]

Improved operating procedures Edit
A Continuous Descent Approach, or CDA, not only reduces fuel burn but also allows airlines to provide quieter approaches for part of the descent to a runway. As the engines are at close to idle power, less noise emissions are produced and combined with new engine technology, the reductions in noise emissions can be large.
A carbon offset is a means of reducing emissions to zero[citation needed] by saving enough carbon to balance the carbon emitted by a particular action. Several airlines have begun offering carbon offsets to passengers to offset the emissions created by their proportion of the flight. Money generated is put to projects around the world to invest in green technology such as renewable energy and research into future technology. Airlines offering carbon offsets include British Airways, easyJet, Continental Airlines, Delta Air Lines, Lufthansa and Qantas although there are many more carriers participating in such schemes.[18][19][20][21]

British Airways’ scheme Edit
British Airways’ carbon offsetting scheme involves paying a fee dependant on aircraft type, class of travel and distance flown and therefore prices vary. Funds generated are currently awarded to three renewable energy projects around the world: Bayin’aobao wind farm in Inner Mongolia, Faxinal dos Guedes hydroelectric power plant in Brazil and Xiaohe hydroelctric power plant in Gansu Province, China.[22]

Continental Airlines’ scheme Edit
Continental Airlines’ carbon offsetting scheme involves paying a fixed fee of $2 to cancel out emissions through reforestation. Passengers can also choose to pay $50 for offsetting emissions through renewable energy projects.

Environmental impact of aviation in the United Kingdom
May 25, 2017

The environmental impact of aviation in the United Kingdom is increasing due to the increasing demand for air travel in the country. In the past 25 years the UK air transport industry has seen sustained growth, and the demand for passenger air travel in particular is forecast to increase more than twofold, to 465 million passengers, by 2030. Two airports; London Heathrow Airport and London Gatwick Airport, are amongst the top ten busiest airports in the world for international passenger traffic. Whilst more than half of all passengers travelling by air in the UK currently travel via the five London area airports, regional airports have experienced the most growth in recent years, due to the success of ‘no-frills’ airlines over the last decade.

The ability of the existing airport infrastructure to meet forecast demand is limited, and government policy published in 2003 supports the development of additional airport capacity by 2030 to address this. The strategy is generally based on making the best use of existing facilities, although an additional five new runways nationwide are considered to be necessary, three of them at the London airports of Stansted, Heathrow and, towards the end of the timeframe involved, Gatwick. This policy is designed to be a balanced and measured approach to the future of the air transport industry; one that recognises both an economic advantage in providing for growth in demand for air travel and also the need to address the consequent environmental impacts. The strategy has been criticised by the House of Commons Environmental Audit Select Committee, by environmentalist and campaign groups, and in research papers, for implementing a predict and provide model that overstates the economic advantages whilst paying insufficient heed to the environmental consequences.

Support for airport expansion is based on an economic case that regards the air transport industry not only as an important industry in its own right, but also as a facilitator of growth for the economy as a whole. One study predicts that the government’s strategy will realise an additional £13 billion per annum in Gross Domestic Product (GDP) by 2030. Another study which is critical of the government approach, and which favours addressing environmental impacts through increased taxation of air transport, indicates a negative economic benefit resulting from airport expansion. In 2006 the industry was responsible for over 6 per cent of all UK carbon emissions, a figure that is set to rise as demand increases. Under current strategies of emissions reduction and growth in air transport, air travel in the UK could account for up to 50 per cent of the UK carbon budget by 2050. Industry attempts to address this issue are longer term efforts based on technological and operational improvements, whilst government policy is based on the inclusion of air transport within emissions trading schemes. Critics advocate a shift in government policy to address environmental impacts by constraining the growth in demand for air travel, primarily through the use of economic instruments to price air travel less attractively. Local environmental issues include noise and air quality, and the impact of these, particularly in the case of the former, is subject to debate. Government policy generally is that these are local issues best addressed locally, and has introduced legislation designed to facilitate this.
Air transport in the United Kingdom is a growth industry. In the period 1981 to 2006 the number of terminal passengers increased by 400 per cent and air transport movements by 250 per cent.[1][2] Although the transport of freight declined slightly year on year between 2004 and 2006, in the decade since 1996 air freight has increased by 31 per cent.[3] During the period in which government policy was being formulated the number of passengers exceeded 200 million, and in 2006 the industry handled over 236 million passengers (up 3 per cent from the previous year), with nearly 2.4 million air transport movements (up 1.8 per cent).[2][4][5]

Infrastructure Edit
Air traffic services for all UK airspace is provided by National Air Traffic Services (NATS), which also provides air traffic control at 15 airports.[6] The largest airport operator is BAA Limited, owner of six UK airports including London Heathrow airport.[7] In some cases airport ownership is in the hands of local government authorities rather than private businesses, and the largest UK owned operator, Manchester Airports Group, operator of Manchester Airport, Bournemouth Airport, East Midlands Airport, and Humberside Airport, is owned by a consortium of 10 Manchester area local authorities.[8] Whilst the number of airports in the UK runs into hundreds, many are smaller aerodromes dealing with general aviation rather than air transport. In terms of the latter, statistics are collected from 59 main airports, and the largest concentration of services is located in the London and South East of England areas.

Largest UK airports 2006
Heathrow is the largest airport in the country, handling over 67 million terminal passengers in 2006, making it the third busiest airport in the world, and the busiest if measured by the number of international passengers.[9][10] Nearly a third of all overseas residents visiting the UK enter the country via this airport, which also handles more than a fifth of all overseas visits by UK residents.[11] Even though there are no dedicated freight services operating out of Heathrow, the practise of transporting cargo in the holds of passenger aircraft means that this airport still accounts for more than half of all freight handled by UK airports.[12] Gatwick airport, with 34 million terminal passengers, is the second largest in the country, eighth busiest in the world for international passenger traffic, and lays claim to the busiest single runway airport in the world.[9][10][13] Between them the five London airports handle nearly 137 million terminal passengers, 59 per cent of the national total.[14] Stansted and East Midlands airports have both experienced large growth in freight handling over the past decade, and these two airports are the major hubs for express freight operations.[15]

Outside of London and the South East, the use of regional airports has increased dramatically in recent years, with the amount of air traffic using these facilities doubling in the period 1995 to 2005.[16] To illustrate this growth, in the five years from 2001 passenger numbers at the regional airports of Exeter International Airport, Bristol International Airport, and Newcastle Airport increased by 191 per cent, 113 per cent, and 60 per cent respectively. In the same period the largest airports experienced some of the slowest growth, with Heathrow passenger numbers increasing by 11 per cent, and those of Gatwick increasing by less than 10 per cent.
The majority of all passengers travelling by air to or from the UK are carried by UK airlines, of which there are around forty, and at the end of 2006 the UK air transport fleet numbered 963 aircraft, flying just under 1.2 million flights and averaging over eight hours of flying daily.[18][19] Together the two largest airlines as measured by passenger numbers; British Airways and easyJet, account for nearly half of the 127 million passengers flown on UK airlines. In terms of capacity, both available and used, British Airways is again the largest airline, whilst easyJet is pushed into third place by Virgin Atlantic Airways. British Airways passenger flights also account for over 50 per cent of all cargo carried by UK airlines, and when combined with its cargo operations the airline carries over 60 per cent of all cargo carried by UK airlines.[20]

The advent in the mid-1990s of ’no-frills’ carriers, such as easyJet, has had a significant impact on air travel in the UK. In 2005 these airlines carried 77.5 million passengers, up from just 4.3 million in 1996.[21] They are responsible for the growth of regional airports, operating from 35 airports in 2006 compared to 10 in 1996, and increasing the choice of international destinations, serving 150 in 2006, compared to 12 a decade earlier.[22][23] The annual rate of growth in the overall demand for air travel has remained stable since 1975, averaging 5.8 per cent annually.[24] Recent growth is being serviced by the no-frills airlines at the expense of traditional carriers which, since 2000, have experienced flat or declining traffic levels.[25][26] In response, traditional carriers have lowered costs to compete more effectively on price, leading to lower prices on the short haul routes serviced by this sector, especially in business fares.[27] They have also limited or reduced capacity and in some cases launched no-frills subsidiaries of their own.[28]

Passenger travel Edit

Passenger numbers 1981–2006
Just over a fifth of all terminal passengers are travelling on domestic routes only, whilst half are travelling between the UK and the rest of the European Union (EU).[29][30] Of the latter, travel between the UK and Spain, France, Germany and Italy account for around half, with Spain almost matching the other three combined in terms of passenger numbers. Outside of the EU, the United States, the Far East, Switzerland and the Middle East together account for just over half of all passengers flying between the UK and the rest of the world, with the USA exceeding the other three combined in terms of passenger numbers.[31] Air travel is the most popular mode of transport for visitors both to and from the UK. In 2005 it was used for 80 per cent of all visits by UK residents travelling overseas and by 74 per cent of all inbound visits.[32] Just over a quarter of all passengers are travelling on business.[33] The advent of no-frills carriers has had a significant effect on passenger travel profiles, with strong growth in business travel from regional airports, and increasing inbound traffic generated for the purposes of non-UK residents visiting friends and relatives based in the UK. Whilst these carriers have been perceived to democratise air travel, providing the opportunity for lower income groups to travel more often, the main result is actually that middle and higher income groups travel more often, and often for shorter trips.[34] Researchers have been raising concern about the globally increasing hypermobility of individuals, involving frequent and often long distance air travel and the resulting environmental and climate impacts.
The availability of airport capacity has been identified as an important constraint on the ability to meet the increasing demand for air travel. In many cases airport capacity is already fully used in meeting current demand. At Heathrow and Gatwick airports the runways are full for “… virtually the whole day”. In 2003 the runway at Birmingham airport was expected to reach full capacity by 2009 at the latest, whilst terminal capacity at Edinburgh airport had reached its limit.[36] Government forecasts that year predicted that by 2030 the number of passengers could rise to between 400 million passengers per annum (mppa) and 600 mppa, representing a two to threefold increase, and a figure of 500 mppa by 2030 was regarded by the government as robust.[4][37] In 2006 the government reported that at 228 mppa the demand for air travel the previous year was in line with the 2003 forecast, but also revised the forecast demand for 2030 downwards to 465 mppa as a result of capacity constraints, even taking into account proposed airport developments.[38]

Government and regulation Edit
The law governing aviation in the UK is defined by the Civil Aviation Act 1982, which is updated periodically with amendments, the latest being the Civil Aviation Act 2006.[39] The government department responsible for legislating changes in national policy and long term strategy relating to aviation is the Department for Transport (DfT). At the operational level the independently run Civil Aviation Authority (CAA) regulates economic, safety, and consumer protection aspects, as well as airspace policy, although these responsibilities are being increasingly ceded to the European Aviation Safety Agency (EASA).[40] International aspects of air transport are regulated by agreements made within the International Civil Aviation Organisation (ICAO) as established by the Chicago Convention, whilst most new legislation is now made at the European level through the European Civil Aviation Conference (ECAC). As a consequence, other than in airport development, there are few aspects of the air transport industry in which the government can act in isolation.
Whilst airport development in the UK is subject to local planning authority processes, the government regards airports as an important part of the national infrastructure and which therefore requires their development to be planned with a strategic approach.[42] To support this, the government began a three-year public consultation process with the publication in December 2000 of The Future of Aviation consultation document. This outlined the issues underpinning air transport and sought views on how they should be addressed in any future policy.[43] One of the main questions asked was whether policy should focus on meeting demand or whether it should focus instead on limiting the negative effects of air transport. Another key issue for which views were sought was how the industry might best meet the environmental costs it incurs.[44] Between July 2002 and February 2003 a further seven regional consultation documents were published. These focussed on the economic, environmental, social and airspace appraisals relating to options for future airport development specific to the regions, and together they generated half a million responses. During the Spring of 2003 workshops based on a consultation document titled Aviation and the Environment – Using Economic Instruments were held to seek stakeholder views on the desirability and effectiveness of various financial measures that might address the environmental impacts of aviation.[45] The consultation process ended in December 2003 with the publication of The Future of Air Transport White Paper which detailed the government’s conclusions.

The White Paper does not in itself authorise or preclude any development, but seeks instead to define a “national strategic framework for the future development of airport capacity” over the next 30 years.[46] The principal conclusion is that the two extremes of failing to provide additional airport capacity, and encouraging growth without regard for the wider impacts, are equally unacceptable options. Instead a “balanced and measured approach” to the future of air transport in the UK is adopted.[47] This approach is designed to cater for the forecast growth in demand, thus supporting economic prosperity nationally and enabling ordinary people to travel at reasonable cost, whilst at the same time managing and mitigating the environmental impacts of aviation and ensuring that the costs associated with them are reflected in the price of air travel.[48] The strategy seeks to minimise new airport development by making best use of existing facilities, and specific policies.
In December 2006 the government published the Air Transport White Paper Progress Report 2006 to report on progress made in “… delivering a sustainable future for aviation.”[60] The report re-iterates the government’s commitment to the strategy defined in the original White Paper, stating that it “… strikes the right balance between economic, social and environmental goals.”[61] It also reports that; the extra runway at Edinburgh airport is now thought unlikely to be needed before 2020;[62] Bristol airport does not currently see a case to support extending its runway, although the option will be kept under review;[63] the additional runway at Stansted airport is not expected to be operational before 2015;[64] and the runway extension at Liverpool airport is now being proposed for early next decade.[65] Elsewhere, recent forecasts conducted for Birmingham airport indicate that a new runway will not be required there before 2030.[66]

Following the publication of the White Paper, the Project for the Sustainable Development of Heathrow (‘Project Heathrow’ for short) was set up to examine how expansion at Heathrow could best be accomplished within the constraints of the stringent environmental limits the White Paper required.[67] A provisional assessment indicates that increased usage of the existing runways could be realised without increasing the number of people affected by noise if ‘mixed mode’ operations (the simultaneous use of both runways for arrivals and departures) are phased in gradually as noisier aircraft are retired.[68] Indications ahead of the Project Heathrow environmental assessment indicate that increased noise and deterioration in air quality are likely to significantly constrain traffic using a new third runway. These issues are to be addressed as part of a three-month consultation beginning in December 2007, and considerable opposition is being mobilised against the expansion of Heathrow.
The aviation industry and the government have together commissioned two significant studies into the economic impact of air transport, both undertaken by the consultancy Oxford Economic Forecasting (OEF). The first; The Contribution of the Aviation Industry to the UK Economy, was published in 1999 and was used as a source of economic information in The Future of Air Transport White Paper.[71][72] The second study; The Economic Contribution of the Aviation Industry in the UK, co-sponsored by the national tourist agency VisitBritain, was published in October 2006 to extend and update the earlier report, and was used as a source in the Air Transport White Paper Progress Report 2006.[72][73] Both studies concluded that whilst aviation is an important industry in its own right, the most important contribution is as “… a facilitator of growth for the economy as a whole.”[74][75]

Environmental groups dispute the economic benefits that are claimed for air transport, and the OEF reports have been specifically challenged. The Aviation Environment Federation (AEF), publishing the Rebuttal of Oxford Economic Forecasting Report, has labelled the 2006 OEF report “biased and misleading”.[76] AirportWatch, an umbrella movement for national environmental organisations and airport community groups opposed to aviation expansion, has produced a critique of the 2006 OEF report and the DfT’s reliance on economic research that has been “… sponsored by the aviation industry.”[77] In response to government policy supporting further growth in aviation, Friends of the Earth (FoE) published Pie in the Sky in September 2006. This study concludes that the economic benefits of aviation have been exaggerated, and that the costs arising from environmental damage, as well as to other sectors of the economy, are ignored.[78] Also published in 2006, the Environmental Change Institute study Predict and decide – Aviation, climate change and UK policy re-examined the economic arguments made in favour of aviation, concluding that restricting future growth would not necessarily be detrimental to the economy, and could potentially result in some economic benefits.[79]

Direct economic impact Edit
In terms of direct impact on the UK economy, air transport is an £11.4 billion industry, a figure which represents 1.1 per cent of the country’s economy. It employs 186,000 people (full-time equivalents), and indirectly supports an additional 334,000 jobs, although the inclusion of indirect employment as an economic benefit of air transport is disputed.[80][81] In terms of productivity the aviation industry in 2004 was the third most productive, after the oil/gas extraction and utilities sectors, exceeding the national average by a factor of two and a half.[82] The industry is also very capital intensive, accounting for up to 3.5 per cent of total UK business investment in the period 2000 to 2004.[83] Air transport was directly responsible for £3.6 billion in tax and national insurance contributions in 2004/5, which includes £0.9 billion raised in Air Passenger Duty (APD), a figure set to double after APD rates were doubled in February 2007.[84] Because of the global nature of the industry, article 15 of the Chicago Convention effectively prevents the imposition of fuel duty on aviation, and the industry does not pay Value Added Tax (VAT). Environmental groups argue that these, along with duty-free sales, are iniquitous tax concessions valued at £9 billion annually.[85] Despite generating £6.9 billion in exports in 2004, representing 3 per cent of all UK exports and 7 per cent of the total export of services, the patronage in the UK of air transport services provided by overseas airlines resulted in a £3.3 billion balance of payments deficit attributable to the industry.
The government’s response to the challenges of an increasingly global economy is to build a “strong, modern knowledge economy”,[87] and the 2006 OEF study concludes that the UK economy is “…set to become increasingly dependent on aviation as the structure of the economy evolves.”[88] The availability of air transport services is regarded as an important factor in facilitating business activities, with benefits being realised in sales and marketing activities, customer and supplier relationships, the ability to serve a wider market, access to emerging markets, and more efficient production.[89] Within industry sectors that are likely to support the development of a knowledge based economy, such as pharmaceuticals, banking and finance, communication services, computer services etc., there is conflicting evidence about a correlation between growth in a sector and that sector’s use of air travel,[90] although survey results show that knowledge based services and high-tech manufacturing businesses are more dependent on air transport for sales than their more traditional economy counterparts.[91]

The most successful example of the country’s economic evolution is the international financial services industry based in London. Within this sector aviation services are seen as critically important for both businesses and their clients, even in the era of video-conferencing. London’s air transport services are widely regarded within the London business community surveyed by the OEF to provide a competitive advantage over the rest of Europe, and expansion of airport capacity in the South East has significant support.[92] Whilst these economic contributions are not disputed by environmental groups, they are not considered as sufficient justification to support further growth in air transport services which would primarily service increased demand for leisure travel rather than a business travel market which is already well served.[93]

Transport links generally are regarded as an important factor which affects a company’s decision on where to locate, and thus invest, although the latest survey shows quality of telecommunications moving above transport in importance.[94] Survey evidence indicates that a quarter of companies regard access to air services as an important factor in the decision of where in the UK to locate operations, whilst one in ten companies report that the absence of good air transport links has affected their decision to invest in the UK.[95] The survey has been criticised as suffering from a poor response rate and therefore open to bias,[96] though this issue has been recognised and rationalised by the report’s authors
Tourism is an industry where the influence of air transport services is more obvious. In 2005 some 22 million overseas visitors arrived by air, spending around £12 billion (1.1 per cent of GDP) and supporting 170,000 jobs in the tourist industry.[98] In the same year air travel also accounted for 36 million trips abroad by UK tourists, and UK tourists as a whole spend twice as much abroad as overseas visitors spend in the UK.[99] This has led to the assertion that aviation represents a “net negative effect” on the UK tourism industry, and that restraining demand for air travel would encourage more domestic tourism, with the consequent economic benefit of reducing the tourism deficit.[100]

Exports and imports by air in 2005 were estimated at £62.7 billion and £59.6 billion respectively, with a significant majority of air freight operations being conducted with countries outside of the EU,[12] and express freight operations transporting 5 per cent by value of all UK exports in 2004.[101] Whilst export/import facilities provide opportunities for international trade and competition, they are not without negative effect, and British horticulture is one example of domestic industry damaged by cheap imports.[102][103]

Forecast economic impact Edit
Attempts to quantify the economic impact of growth in the air transport sector generate results which depend on assumptions made, and therefore the viewpoint of the organisation making the analysis. The OEF study has produced a figure of £2.5 billion per annum of additional GDP by 2015 for Heathrow, or £7 billion per annum by 2030 if a third runway is built there. Full implementation of the White Paper runway proposals resulted in a forecast yield of an additional £13 billion per annum in GDP by 2030.[104] Calculations done for the AEF, based on a new runway at Stansted, and which assume increased taxation of the industry, result in a negative economic benefit.
External costs, also referred to as hidden costs, are quantifications of the environmental and climate impacts of air transport. Whilst setting a financial value on all such impacts is difficult to do precisely, figures have been produced for the most significant. In 2000 the government valued the annual cost of climate change induced by greenhouse gas emissions from UK air transport at £1.4 billion, rising to £4.8 billion per annum by 2030.[106] The impact of noise was costed at around £25 million per annum in 2000, and for the same year the impact on air quality was costed at between £119 million and £236 million per annum.[107] Based on figures produced by the European Environment Agency the AEF has calculated a much higher total external cost for 2000 of around £6 billion.[108]

Whilst carbon emissions from all UK activities other than aviation had declined by 9 per cent in the 10 years between 1990 and 2000, carbon emissions from aviation activities doubled in the same period.[109] Air transport in the UK accounted for 6.3 per cent of all UK carbon emissions in 2006.[110] When the radiative forcing impact of other emissions are taken into account the total impact of emissions attributable to aviation is estimated to be twice that of its carbon emissions alone.[111] Although the government has committed to reducing total UK carbon emissions by 60 per cent from existing levels by 2050, its policy is based on the use of “… economic instruments to ensure that growing industries are catered for within a reducing total.”[112] Even if this reduction in total carbon emissions is achieved, research published in February 2006 concluded that aviation could account for between 24 per cent and 50 per cent of the UK’s carbon budget by 2050.[113]

The government recognises that there are no viable alternative aviation fuels, and whilst it accepts that the exemption of aviation fuel from fuel tax is anomalous, it sees no scope for a unilateral approach in addressing this.[114] The strategy adopted in the White Paper seeks to mitigate the global impact of air transport primarily through emissions trading schemes. Although the Kyoto Protocol implemented emissions trading as a means to reduce emissions at national levels, the global nature of air transport means that all air travel is excluded from this mechanism. The government is seeking to redress this through the International Civil Aviation Organisation (ICAO), which has been working on the environmental issue since 1998, but progress is slow.[115] In the meantime efforts are being made to include aviation in the EU Emission Trading Scheme (EU ETS) with an original target to implement this by 2008.[116] In 2006 the government re-affirmed this policy as the best approach for addressing the climate change impacts of aviation, and current proposals aim at accomplishing this for all flights within the EU by 2011, with the scheme being extended to include all flights to and from the EU the following year.[
The aviation industry is seeking to reduce its climate change impacts by becoming more fuel efficient, and in the last 40 years fuel efficiency has more than doubled.[120] In June 2005, Sustainable Aviation; a joint initiative involving a number of UK airlines, airports, manufacturers and the air traffic service provider NATS, was launched with a vision statement relating to environmental issues of “…removing or minimising any negative impacts on the local and global environment…”.[121] One of its commitments is to achieve, by means of airframe, engine and air traffic management improvements, a 50% reduction in CO
2 emissions, and an 80% reduction in NOx emissions in new aircraft of 2020 relative to new aircraft in 2000. These are however long term aspirations, and whilst progress is being made in engine development, the more immediate efforts of Sustainable Aviation to address climate change are directed towards supporting research, common reporting of emissions, emissions trading, and personal offsetting.[122][123]

Critics of an expansionist policy consider the EU ETS to be too late and to price carbon too low to adequately mitigate the climate change impact of aviation emissions.[124] Instead they advocate addressing these impacts by constraining demand for air travel. The study Predict and Decide – Aviation, climate change and UK policy, noting that a 10 per cent increase in fares generates a 5 to 15 per cent reduction in demand, recommends that the government should seek an alternative aviation policy based on managing demand rather than providing for it.[125] This would be accomplished via a strategy that presumes “… against the expansion of UK airport capacity” and constrains demand by the use of economic instruments to price air travel less attractively.[126] In another study the levying of £9 billion of taxes is calculated to constrain the forecast growth in demand by 2030 to 315 million passengers, reducing the annual rate of growth to 2 per .

Have you heard about Environmental impact of aviation ???
May 25, 2017

The environmental impact of aviation occurs because aircraft engines emit heat, noise, particulates and gases which contribute to climate change[1][2] and global dimming.[3] Among others airplanes emit particles and gases such as carbon dioxide (CO2), water vapor, hydrocarbons, carbon monoxide, nitrogen oxides, sulfur oxides, lead and black carbon which interact among themselves and with the atmosphere.[4]

Despite emission reductions from automobiles and more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air travel in recent years contributes to an increase in total pollution attributable to aviation. From 1992 to 2005, passenger kilometers increased 5.2% per year. And in the European Union, greenhouse gas emissions from aviation increased by 87% between 1990 and 2006.[5]

Comprehensive research shows that despite anticipated efficiency innovations to airframes, engines, aerodynamics and flight operations, there is no end in sight – even many decades out – to rapid growth in CO2 emissions from air travel and air freight,[6][7] due to projected continual growth in air travel.[8][9] This is because international aviation emissions have escaped international regulation up to the ICAO triennial conference in October 2016 agreed on the CORSIA offset scheme[citation needed], and because of the lack of taxes on aviation fuel worldwide, lower fares become more frequent than otherwise which gives a competitive advantage over other transportation modes.[citation needed] Unless market constraints are put in place this growth in aviation’s emissions will result in the sector’s emissions amounting to all or nearly all of the annual global CO2 emissions budget by mid-century, if climate change is to be held to a temperature increase of 2 °C or less.[10]

There is an ongoing debate about possible taxation of air travel and the inclusion of aviation in an emissions trading scheme, with a view to ensuring that the total external costs of aviation are taken into account.
Like all human activities involving combustion, most forms of aviation release carbon dioxide (CO2) and other greenhouse gases into the Earth’s atmosphere, contributing to the acceleration of global warming[12] and (in the case of CO2) ocean acidification.[13] These concerns are highlighted by the present volume of commercial aviation and its rate of growth. Globally, about 8.3 million people fly daily (3 billion occupied seats per year), twice the total in 1999.[14] U.S. airlines alone burned about 16.2 billion gallons of fuel during the twelve months between October 2013 and September 2014.[15]

In addition to the CO2 released by most aircraft in flight through the burning of fuels such as Jet-A (turbine aircraft) or Avgas (piston aircraft), the aviation industry also contributes greenhouse gas emissions from ground airport vehicles and those used by passengers and staff to access airports, as well as through emissions generated by the production of energy used in airport buildings, the manufacture of aircraft and the construction of airport infrastructure.[16]

While the principal greenhouse gas emission from powered aircraft in flight is CO2, other emissions may include nitric oxide and nitrogen dioxide (together termed oxides of nitrogen or NOx), water vapour and particulates (soot and sulfate particles), sulfur oxides, carbon monoxide (which bonds with oxygen to become CO2 immediately upon release), incompletely burned hydrocarbons, tetraethyllead (piston aircraft only), and radicals such as hydroxyl, depending on the type of aircraft in use.[17] Emissions weighting factor (EWFs) i.e., the factor by which aviation CO2 emissions should be multiplied to get the CO2-equivalent emissions for annual fleet average conditions is in the range 1.3–2.9.[18]

Mechanisms and cumulative effects of aviation on climate Edit
In 1999 the contribution of civil aircraft-in-flight to global CO2 emissions was estimated to be around 2%.[17] However, in the case of high-altitude airliners which frequently fly near or in the stratosphere, non-CO2 altitude-sensitive effects may increase the total impact on anthropogenic (human-made) climate change significantly.[17] A 2007 report from Environmental Change Institute / Oxford University posits a range closer to 4 percent cumulative effect.[19] Subsonic aircraft-in-flight contribute to climate change[17] in four ways:

Carbon dioxide (CO2) Edit
CO2 emissions from aircraft-in-flight are the most significant and best understood[20] element of aviation’s total contribution to climate change. The level and effects of CO2 emissions are currently believed to be broadly the same regardless of altitude (i.e. they have the same atmospheric effects as ground based emissions). In 1992, emissions of CO2 from aircraft were estimated at around 2% of all such anthropogenic emissions, and that year the atmospheric concentration of CO2 attributable to aviation was around 1% of the total anthropogenic increase since the industrial revolution, having accumulated primarily over just the last 50 years.
At the high altitudes flown by large jet airliners around the tropopause, emissions of NOx are particularly effective in forming ozone (O3) in the upper troposphere. High altitude (8–13 km) NOx emissions result in greater concentrations of O3 than surface NOx emissions, and these in turn have a greater global warming effect. The effect of O3 concentrations are regional and local (as opposed to CO2 emissions, which are global).[citation needed]

NOx emissions also reduce ambient levels of methane, another greenhouse gas, resulting in a climate cooling effect. But this effect does not offset the O3 forming effect of NOx emissions. It is now believed that aircraft sulfur and water emissions in the stratosphere tend to deplete O3, partially offsetting the NOx-induced O3 increases. These effects have not been quantified.[21] This problem does not apply to aircraft that fly lower in the troposphere, such as light aircraft or many commuter aircraft.
One of the products of burning hydrocarbons in oxygen is water vapour, a greenhouse gas. Water vapour produced by aircraft engines at high altitude, under certain atmospheric conditions, condenses into droplets to form Condensation trails, or contrails. Contrails are visible line clouds that form in cold, humid atmospheres and are thought to have a global warming effect (though one less significant than either CO2 emissions or NOx induced effects).[22] Contrails are extremely rare from lower-altitude aircraft, or from propeller-driven aircraft or rotorcraft.

Cirrus clouds have been observed to develop after the persistent formation of contrails and have been found to have a global warming effect over-and-above that of contrail formation alone. There is a degree of scientific uncertainty about the contribution of contrail and cirrus cloud formation to global warming and attempts to estimate aviation’s overall climate change contribution do not tend to include its effects on cirrus cloud enhancement.[20] However, a 2015 study found that artificial cloudiness caused by contrail “outbreaks” reduce the difference between daytime and nighttime temperatures. The former are decreased and the latter are increased, in comparison to temperatures the day before and the day after such outbreaks.[23] On days with outbreaks the day/night temperature difference was diminished by about 6F° in the U.S. South and 5F° in the Midwest.[24]

Particulates Edit
Least significant is the release of soot and sulfate particles. Soot absorbs heat and has a warming effect; sulfate particles reflect radiation and have a small cooling effect. In addition, they can influence the formation and properties of clouds.[25] All aircraft powered by combustion will release some amount of soot.

Greenhouse gas emissions per passenger kilometre Edit
Averaged emissions Edit
Emissions of passenger aircraft per passenger kilometre vary extensively because of differing factors such as the size and type aircraft, the altitude and the percentage of passenger or freight capacity of a particular flight, and the distance of the journey and number of stops en route. Also, the effect of a given amount of emissions on climate (radiative forcing) is greater at higher altitudes: see below. Some representative figures for CO2 emissions are provided by LIPASTO’s survey of average direct emissions (not accounting for high-altitude radiative effects) of airliners expressed as CO2 and CO2 equivalent per passenger kilometre:[26]

Domestic, short distance, less than 463 km (288 mi): 257 g/km CO2 or 259 g/km (14.7 oz/mile) CO2e
Domestic, long distance, greater than 463 km (288 mi): 177 g/km CO2 or 178 g/km (10.1 oz/mile) CO2e
Long distance flights: 113 g/km CO2 or 114 g/km (6.5 oz/mile) CO2e
These emissions are similar to a four-seat car with one person on board;[27] however, flying trips often cover longer distances than would be undertaken by car, so the total emissions are much higher. For perspective, per passenger a typical economy-class New York to Los Angeles round trip produces about 715 kg (1574 lb) of CO2 (but is equivalent to 1,917 kg (4,230 lb) of CO2 when the high altitude “climatic forcing” effect is taken into account).[28] Within the categories of flights above, emissions from scheduled jet flights are substantially higher than turboprop or chartered jet flights. About 60% of aviation emissions arise from international flights, and these flights are not covered by the Kyoto Protocol and its emissions reduction targets.[29]

Figures from British Airways suggest carbon dioxide emissions of 100g per passenger kilometre for large jet airliners (a figure which does not account for the production of other pollutants or condensation trails).[30]

Emissions by passenger class, and effects of seating configuration Edit
In 2013 the World Bank published a study of the effect on CO2 emissions of its staff’s travel in business class or first class, versus using economy class.[31]
A related article by the International Council on Clean Transport notes further regarding the effect of seating configurations on carbon emissions that:[33]

The A380 is marketed as a “green giant” and one of the most environmentally advanced aircraft out there. But that spin is based on a maximum-capacity aircraft configuration, or about 850 economy passengers. In reality, a typical A380 aircraft has 525 seats. Its fuel performance is comparable to that of a B747-400 ER and even about 15% worse than a B777-300ER on a passenger-mile basis (calculated using Piano-5 on a flight from AUH to LHR, assuming an 80% passenger load factor, and in-service fleet average seat counts).
In attempting to aggregate and quantify the total climate impact of aircraft emissions the Intergovernmental Panel on Climate Change (IPCC) has estimated that aviation’s total climate impact is some 2-4 times that of its direct CO2 emissions alone (excluding the potential impact of cirrus cloud enhancement).[17] This is measured as radiative forcing. While there is uncertainty about the exact level of impact of NOx and water vapour, governments have accepted the broad scientific view that they do have an effect. Globally in 2005, aviation contributed “possibly as much as 4.9% of radiative forcing.”[29] UK government policy statements have stressed the need for aviation to address its total climate change impacts and not simply the impact of CO2.[34]

The IPCC has estimated that aviation is responsible for around 3.5% of anthropogenic climate change, a figure which includes both CO2 and non-CO2 induced effects. The IPCC has produced scenarios estimating what this figure could be in 2050. The central case estimate is that aviation’s contribution could grow to 5% of the total contribution by 2050 if action is not taken to tackle these emissions, though the highest scenario is 15%.[17] Moreover, if other industries achieve significant cuts in their own greenhouse gas emissions, aviation’s share as a proportion of the remaining emissions could also rise.

Future emission levels Edit
Even though there have been significant improvements in fuel efficiency through aircraft technology and operational management as described here, these improvements are being continually eclipsed by the increase in air traffic volume.

A December 2015 report finds that aircraft could generate 43 Gt of carbon pollution through to 2050, consuming almost 5% of the remaining global climate budget. Without regulation, global aviation emissions may triple by mid-century and could emit more than 3 Gt of carbon annually under a high-growth, business-as-usual scenario. Efforts to bring aviation emissions under an effective global accord have so far largely failed, despite there being a number of technological and operational improvements on offer.[35][36]

Continual increases in travel and freight Edit
From 1992 to 2005, passenger kilometers increased 5.2% per year, even with the disruptions of 9/11 and two significant wars. Since the onset of the current recession:

During the first three quarters of 2010, air travel markets expanded at an annualized rate approaching 10%. This is similar to the rate seen in the rapid expansion prior to the recession. November’s results mean the annualized rate of growth so far in Q4 drops back to around 6%. But this is still in line with long run rates of traffic growth seen historically. The level of international air travel is now 4% above the pre-recession peak of early 2008 and the current expansion looks to have further to run.[37]

Air freight reached a new high point in May (2010) but, following the end of inventory restocking activity, volumes have slipped back to settle at a similar level seen just before the onset of recession. Even so, that means an expansion of air freight during 2010 of 5-6% on an annualized basis – close to historical trend. With the stimulus of inventory restocking activity removed, further growth in air freight demand will be driven by end consumer demand for goods which utilize the air transport supply chain. … The end of the inventory cycle does not mean the end of volume expansion but markets are entering a slower growth phase.
In a 2008 presentation[12] and paper [38] Professor Kevin Anderson of the Tyndall Centre for Climate Change Research showed how continued aviation growth in the UK threatens the ability of that nation to meet CO2 emission reduction goals necessary to contain the century-end temperature increase to even 4 or 6C°. (See also: the 4 Degrees and Beyond International Climate Conference (2009)[39] and its proceedings.)[40] His charts show the projected domestic aviation carbon emission increase for the UK as growing from 11 MT in 2006 to 17 MT in 2012, at the UK’s historic annual emission growth rate of 7%. Beyond 2012 if the growth rate were reduced to 3% yearly, carbon emissions in 2030 would be 28 MT, which is 70% of the UK’s entire carbon emissions budget that year for all sectors of society. This work also suggests the foreseeable future which confronts many other nations that have high dependency on aviation. “Hypermobile Travelers”,[41] an academic study by Stefan Gössling et al. (2009) in the book “Climate Change and Aviation”,[42] also points to the dilemma caused by the increasing hypermobility of air travelers both in particular nations and globally.[43]

Scope for improvement Edit
Aircraft efficiency Edit
While it is true that late model jet aircraft are significantly more fuel efficient (and thus emit less CO2 in particular) than the earliest jet airliners,[44][45] new airliner models in the first decade of the 21st Century were barely more efficient on a seat-mile basis than the latest piston-powered airliners of the late 1950s (e.g. Constellation L-1649-A and DC-7C).[45] Claims for a high gain in efficiency for airliners over recent decades (while true in part) has been biased high in most studies, by using the early inefficient models of jet airliners as a baseline. Those aircraft were optimized for increased revenue, including increased speed and cruising altitude, and were quite fuel inefficient in comparison to their piston-powered forerunners.[45]

Today, turboprop aircraft – probably in part because of their lower cruising speeds and altitudes (similar to the earlier piston-powered airliners) compared to jet airliners – play an obvious role in the overall fuel efficiency of major airlines that have regional carrier subsidiaries.[46] For example, although Alaska Airlines scored at the top of a 2011-2012 fuel efficiency ranking, if its large regional carrier – turbo-prop equipped Horizon Air – were dropped from the lumped-in consideration, the airline’s ranking would be somewhat lower, as noted in the ranking study.

Aircraft manufacturers are striving for reductions in both CO2 and NOx emissions with each new generation of design of aircraft and engine.[47] While the introduction of more modern aircraft represents an opportunity to reduce emissions per passenger kilometre flown, aircraft are major investments that endure for many decades, and replacement of the international fleet is therefore a long-term proposition which will greatly delay realizing the climate benefits of many kinds of improvements. Engines can be changed at some point, but nevertheless airframes have a long life.[citation needed] Moreover, rather than being linear from one year to the next the improvements to efficiency tend to diminish over time, as reflected in the histories of both piston and jet powered aircraft.[45]

A 2014 life-cycle assessment of the cradle-to-grave reduction in CO2 by a carbon-fiber-reinforced polymer (CFRP) airliner such as a Boeing 787 – including its manufacture, operations and eventual disposal – has shown that by 2050 such aircraft could reduce the airline industry’s CO2 emissions by 14-15%, compared use of conventional airliners.[48] The benefit of CFRP technology is not higher than that amount of reduction, despite the lighter weight and substantially lower fuel consumption of such aircraft, “because of the limited fleet penetration by 2050 and the increased demand for air travel due to lower operating costs.”
Research projects such as Boeing’s ecoDemonstrator program have sought to identify ways of improving the efficiency of commercial aircraft operations. The U.S. government has encouraged such research through grant programs, including the FAA’s Continuous Lower Energy, Emissions and Noise (CLEEN) program, and NASA’s Environmentally Responsible Aviation (ERA) Project.

Adding an electric drive to the airplane’s nose wheel may improve fuel efficiency during ground handling. This addition would allow taxiing without use of the main engines.[33][34][35] [49][50][51]

Another proposed change is the integrating of an Electromagnetic Aircraft Launch System to the airstrips of airports. Some companies such as Airbus are currently researching this possibility. The adding of EMALS would allow the civilian aircraft to use considerably less fuel (as a lot of fuel is spend during take off, and in comparison, less during flight – when calculated per km flown). The idea is to have the aircraft take off at regular aircraft speed, and only use the catapult for take-off, not for landing.[52][53]

Other opportunities arise from the optimisation of airline timetables, route networks and flight frequencies to increase load factors (minimise the number of empty seats flown),[54] together with the optimisation of airspace. However, these are each one-time gains, and as these opportunities are successively fulfilled, diminishing returns can be expected from the remaining opportunities.

Another possible reduction of the climate-change impact is the limitation of cruise altitude of aircraft. This would lead to a significant reduction in high-altitude contrails for a marginal trade-off of increased flight time and an estimated 4% increase in CO2 emissions. Drawbacks of this solution include very limited airspace capacity to do this, especially in Europe and North America and increased fuel burn because jet aircraft are less efficient at lower cruise altitudes.[55]

While they are not suitable for long-haul or transoceanic flights, turboprop aircraft used for commuter flights bring two significant benefits: they often burn considerably less fuel per passenger mile, and they typically fly at lower altitudes, well inside the tropopause, where there are no concerns about ozone or contrail production.
Some scientists and companies such as GE Aviation and Virgin Fuels are researching biofuel technology for use in jet aircraft.[56] Some aircraft engines, like the Wilksch WAM120 can (being a 2-stroke Diesel engine) run on straight vegetable oil. Also, a number of Lycoming engines run well on ethanol.

In addition, there are also several tests done combining regular petrofuels with a biofuel. For example, as part of this test Virgin Atlantic Airways flew a Boeing 747 from London Heathrow Airport to Amsterdam Schiphol Airport on 24 February 2008, with one engine burning a combination of coconut oil and babassu oil.[56] Greenpeace’s chief scientist Doug Parr said that the flight was “high-altitude greenwash” and that producing organic oils to make biofuel could lead to deforestation and a large increase in greenhouse gas emissions.[56] Also, the majority of the world’s aircraft are not large jetliners but smaller piston aircraft, and with major modifications many are capable of using ethanol as a fuel.[57] Another consideration is the vast amount of land that would be necessary to provide the biomass feedstock needed to support the needs of aviation, both civil and military.[58]

In December 2008, an Air New Zealand jet completed the world’s first commercial aviation test flight partially using jatropha-based fuel. Jatropha, used for biodiesel, can thrive on marginal agricultural land where many trees and crops won’t grow, or would produce only slow growth yields.[59][60] Air New Zealand set several general sustainability criteria for its Jatropha, saying that such biofuels must not compete with food resources, that they must be as good as traditional jet fuels, and that they should be cost competitive with existing fuels.[61]

In January 2009, Continental Airlines used a sustainable biofuel to power a commercial aircraft for the first time in North America. This marks the first sustainable biofuel demonstration flight by a commercial carrier using a twin-engined aircraft, a Boeing 737-800, powered by CFM International CFM56-7B engines. The biofuel blend included components derived from algae and jatropha plants.[62]

One fuel biofuel alternative to avgas that is under development is Swift Fuel. Swift fuel was approved as a test fuel by ASTM International in December 2009, allowing the company to continue their research and to pursue certification testing. Mary Rusek, president and co-owner of Swift Enterprises predicted at that time that “100SF will be comparably priced, environmentally friendlier and more fuel-efficient than other general aviation fuels on the market”.[63][64]

As of June 2011, revised international aviation fuel standards officially allow commercial airlines to blend conventional jet fuel with up to 50 percent biofuels. The renewable fuels “can be blended with conventional commercial and military jet fuel through requirements in the newly issued edition of ASTM D7566, Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons”.[65]

In December 2011, the FAA announced it is awarding $7.7 million to eight companies to advance the development of drop-in commercial aviation biofuels, with a special focus on ATJ (alcohol to jet) fuel. As part of its CAAFI (Commercial Aviation Alternative Fuel Initiative) and CLEEN (Continuous Lower Emissions, Energy and Noise) programs, the FAA plans to assist in the development of a sustainable fuel (from alcohols, sugars, biomass, and organic matter such as pyrolysis oils) that can be “dropped in” to aircraft without changing current infrastructure. The grant will also be used to research how the fuels affect engine durability and quality control standards.[66]

Finally, liquified natural gas is another fuel that is used in some airplanes. Besides the lower GHG emissions (depending from where the natural gas was obtained from), another major benefit to airplane operators is the price, which is far lower than the price for jet fuel.
The German video short The Bill[67] explores how travel and its impacts are commonly viewed in everyday developed-world life, and the social pressures that are at play. British writer George Marshall has investigated common rationalizations that act as barriers to making personal choices to travel less, or to justify recent trips. In an informal research project, “one you are welcome to join”, he says, he deliberately steered conversations with people who are attuned to climate change problems to questions about recent long-distance flights and why the travel was justified. Reflecting on actions contrary to their beliefs, he noted, “(i)ntriguing as their dissonance may be, what is especially revealing is that every one of these people has a career that is predicated on the assumption that information is sufficient to generate change – an assumption that a moment’s introspection would show them was deeply flawed.”[68]

Business and professional choices Edit
With most international conferences having hundreds if not thousands of participants, and the bulk of these usually traveling by plane, conference travel is an area where significant reductions in air-travel-related GHG emissions could be made. … This does not mean non-attendance. (Reay 2004)
For example, by 2003 Access Grid technology has already been successfully used to host several international conferences,[69] and technology has likely progressed substantially since then. The Tyndall Centre for Climate Change Research has been systematically studying means to change common institutional and professional practices that have led to large carbon footprints of travel by research scientists, and issued a report. (Le Quéré et al. 2015).[70][71][72]

Ending incentives to fly—frequent flyer programs Edit
Over 130 airlines have “frequent flyer programs” based at least in part on miles, kilometers, points or segments for flights taken. Globally, such programs included about 163 million people as reported in 2006.[73] These programs benefit airlines by habituating people to air travel and, through the mechanics of partnerships with credit card companies and other businesses, in which high profit margin revenue streams can amount to selling free seats for a high price.

Some features we got on transportation

Relocation of travelers and cargo are the most common uses of transport. However, other uses exist, such as the strategic and tactical relocation of armed forces during warfare, or the civilian mobility construction or emergency equipment.
Passenger transport, or travel, is divided into public and private transport. Public transport is scheduled services on fixed routes, while private is vehicles that provide ad hoc services at the riders desire. The latter offers better flexibility, but has lower capacity, and a higher environmental impact. Travel may be as part of daily commuting, for business, leisure or migration.

Short-haul transport is dominated by the automobile and mass transit. The latter consists of buses in rural and small cities, supplemented with commuter rail, trams and rapid transit in larger cities. Long-haul transport involves the use of the automobile, trains, coaches and aircraft, the last of which have become predominantly used for the longest, including intercontinental, travel. Intermodal passenger transport is where a journey is performed through the use of several modes of transport; since all human transport normally starts and ends with walking, all passenger transport can be considered intermodal. Public transport may also involve the intermediate change of vehicle, within or across modes, at a transport hub, such as a bus or railway station.

Taxis and buses can be found on both ends of the public transport spectrum. Buses are the cheaper mode of transport but are not necessarily flexible, and taxis are very flexible but more expensive. In the middle is demand-responsive transport, offering flexibility whilst remaining affordable.

International travel may be restricted for some individuals due to legislation and visa requirements.

Freight Edit
Main article: Shipping
Freight transport, or shipping, is a key in the value chain in manufacturing.[17] With increased specialization and globalization, production is being located further away from consumption, rapidly increasing the demand for transport.[18] Transportation creates place utility by moving the goods from the place of production to the place of consumption. While all modes of transport are used for cargo transport, there is high differentiation between the nature of the cargo transport, in which mode is chosen.[19] Logistics refers to the entire process of transferring products from producer to consumer, including storage, transport, transshipment, warehousing, material-handling and packaging, with associated exchange of information.[20] Incoterm deals with the handling of payment and responsibility of risk during transport.[21]
Containerization, with the standardization of ISO containers on all vehicles and at all ports, has revolutionized international and domestic trade, offering huge reduction in transshipment costs. Traditionally, all cargo had to be manually loaded and unloaded into the haul of any ship or car; containerization allows for automated handling and transfer between modes, and the standardized sizes allow for gains in economy of scale in vehicle operation. This has been one of the key driving factors in international trade and globalization since the 1950s.[22]

Bulk transport is common with cargo that can be handled roughly without deterioration; typical examples are ore, coal, cereals and petroleum. Because of the uniformity of the product, mechanical handling can allow enormous quantities to be handled quickly and efficiently. The low value of the cargo combined with high volume also means that economies of scale become essential in transport, and gigantic ships and whole trains are commonly used to transport bulk. Liquid products with sufficient volume may also be transported by pipeline.

Air freight has become more common for products of high value; while less than one percent of world transport by volume is by airline, it amounts to forty percent of the value. Time has become especially important in regards to principles such as postponement and just-in-time within the value chain, resulting in a high willingness to pay for quick delivery of key components or items of high value-to-weight ratio.[23] In addition to mail, common items sent by air include electronics and fashion clothing.
Humans’ first means of transport involved walking, running and swimming. The domestication of animals introduced a new way to lay the burden of transport on more powerful creatures, allowing the hauling of heavier loads, or humans riding animals for greater speed and duration. Inventions such as the wheel and the sled helped make animal transport more efficient through the introduction of vehicles. Water transport, including rowed and sailed vessels, dates back to time immemorial, and was the only efficient way to transport large quantities or over large distances prior to the Industrial Revolution.

The first forms of road transport involved animals, such as horses (domesticated in the 4th or 3rd millennium BCE), oxen (from about 8000 BCE)[24] or humans carrying goods over dirt tracks that often followed game trails. Many early civilizations, including Mesopotamia and the Indus Valley Civilization, constructed paved roads. In classical antiquity, the Persian and Roman empires built stone-paved roads to allow armies to travel quickly. Deep roadbeds of crushed stone underneath kept such roads dry. The medieval Caliphate later built tar-paved roads. The first watercraft were canoes cut out from tree trunks. Early water transport was accomplished with ships that were either rowed or used the wind for propulsion, or a combination of the two. The importance of water has led to most cities that grew up as sites for trading being located on rivers or on the sea-shore, often at the intersection of two bodies of water. Until the Industrial Revolution, transport remained slow and costly, and production and consumption gravitated as close to each other as feasible.
The Industrial Revolution in the 19th century saw a number of inventions fundamentally change transport. With telegraphy, communication became instant and independent of the transport of physical objects. The invention of the steam engine, closely followed by its application in rail transport, made land transport independent of human or animal muscles. Both speed and capacity increased rapidly, allowing specialization through manufacturing being located independently of natural resources. The 19th century also saw the development of the steam ship, which sped up global transport.

With the development of the combustion engine and the automobile around 1900, road transport became more competitive again, and mechanical private transport originated. The first “modern” highways were constructed during the 19th century[citation needed] with macadam. Later, tarmac and concrete became the dominant paving materials. In 1903 the Wright brothers demonstrated the first successful controllable airplane, and after World War I (1914-1918)aircraft became a fast way to transport people and express goods over long distances.[25]

After World War II (1939-1945) the automobile and airlines took higher shares of transport, reducing rail and water to freight and short-haul passenger services.[26] Scientific spaceflight began in the 1950s, with rapid growth until the 1970s, when interest dwindled. In the 1950s the introduction of containerization gave massive efficiency gains in freight transport, fostering globalization.[22] International air travel became much more accessible in the 1960s with the commercialization of the jet engine. Along with the growth in automobiles and motorways, rail and water transport declined in relative importance. After the introduction of the Shinkansen in Japan in 1964, high-speed rail in Asia and Europe started attracting passengers on long-haul routes away from airlines.[26]

Early in U.S. history,[when?] private joint-stock corporations owned most aqueducts, bridges, canals, railroads, roads, and tunnels. Most such transportation infrastructure came under government control in the late 19th and early 20th centuries, culminating in the nationalization of inter-city passenger rail-service with the establishment of Amtrak. Recently,[when?] however, a movement to privatize roads and other infrastructure has gained some[quantify] ground and adherents.
Transport is a key necessity for specialization—allowing production and consumption of products to occur at different locations. Transport has throughout history been a spur to expansion; better transport allows more trade and a greater spread of people. Economic growth has always been dependent on increasing the capacity and rationality of transport.[28] But the infrastructure and operation of transport has a great impact on the land and is the largest drainer of energy, making transport sustainability a major issue.

Due to the way modern cities and communities are planned and operated, a physical distinction between home and work is usually created, forcing people to transport themselves to places of work, study, or leisure, as well as to temporarily relocate for other daily activities. Passenger transport is also the essence of tourism, a major part of recreational transport. Commerce requires the transport of people to conduct business, either to allow face-to-face communication for important decisions or to move specialists from their regular place of work to sites where they are needed.

Planning Edit
Main article: Transport planning
Transport planning allows for high utilization and less impact regarding new infrastructure. Using models of transport forecasting, planners are able to predict future transport patterns. On the operative level, logistics allows owners of cargo to plan transport as part of the supply chain. Transport as a field is also studied through transport economics, a component for the creation of regulation policy by authorities. Transport engineering, a sub-discipline of civil engineering, must take into account trip generation, trip distribution, mode choice and route assignment, while the operative level is handled through traffic engineering.
Because of the negative impacts incurred, transport often becomes the subject of controversy related to choice of mode, as well as increased capacity. Automotive transport can be seen as a tragedy of the commons, where the flexibility and comfort for the individual deteriorate the natural and urban environment for all. Density of development depends on mode of transport, with public transport allowing for better spatial utilization. Good land use keeps common activities close to people’s homes and places higher-density development closer to transport lines and hubs, to minimize the need for transport. There are economies of agglomeration. Beyond transportation some land uses are more efficient when clustered. Transportation facilities consume land, and in cities, pavement (devoted to streets and parking) can easily exceed 20 percent of the total land use. An efficient transport system can reduce land waste.

Too much infrastructure and too much smoothing for maximum vehicle throughput means that in many cities there is too much traffic and many—if not all—of the negative impacts that come with it. It is only in recent years that traditional practices have started to be questioned in many places, and as a result of new types of analysis which bring in a much broader range of skills than those traditionally relied on—spanning such areas as environmental impact analysis, public health, sociologists as well as economists—the viability of the old mobility solutions is increasingly being questioned.
Transport is a major use of energy and burns most of the world’s petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide,[29] for which transport is the fastest-growing emission sector.[30] By subsector, road transport is the largest contributor to global warming.[31] Environmental regulations in developed countries have reduced individual vehicles’ emissions; however, this has been offset by increases in the numbers of vehicles and in the use of each vehicle.[29] Some pathways to reduce the carbon emissions of road vehicles considerably have been studied.[32][33] Energy use and emissions vary largely between modes, causing environmentalists to call for a transition from air and road to rail and human-powered transport, as well as increased transport electrification and energy efficiency.

Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands. By reducing transportation emissions globally, it is predicted that there will be significant positive effects on Earth’s air quality, acid rain, smog and climate change.

What you don’t know about transportation !!!!!

Transport or transportation is the movement of people, animals and goods from one location to another. Modes of transport include air, rail, road, water, cable, pipeline and space. The field can be divided into infrastructure, vehicles and operations. Transport is important because it enables trade between people, which is essential for the development of civilizations.

Transport infrastructure consists of the fixed installations including roads, railways, airways, waterways, canals and pipelines and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations) and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance.

Vehicles traveling on these networks may include automobiles, bicycles, buses, trains, trucks, people, helicopters, watercraft, spacecraft and aircraft.

Operations deal with the way the vehicles are operated, and the procedures set for this purpose including financing, legalities and policies. In the transport industry, operations and ownership of infrastructure can be either public or private, depending on the country and mode.

Passenger transport may be public, where operators provide scheduled services, or private. Freight transport has become focused on containerization, although bulk transport is used for large volumes of durable items. Transport plays an important part in economic growth and globalization, but most types cause air pollution and use large amounts of land. While it is heavily subsidized by governments, good planning of transport is essential to make traffic flow and restrain urban sprawl.
A mode of transport is a solution that makes use of a particular type of vehicle, infrastructure and operation. The transport of a person or of cargo may involve one mode or several of the modes, with the latter case being called intermodal or multimodal transport. Each mode has its own advantages and disadvantages, and will be chosen for a trip on the basis of cost, capability, and route.
Human powered transport, a form of sustainable transportation, is the transport of people and/or goods using human muscle-power, in the form of walking, running and swimming. Modern technology has allowed machines to enhance human power. Human-powered transport remains popular for reasons of cost-saving, leisure, physical exercise, and environmentalism; it is sometimes the only type available, especially in underdeveloped or inaccessible regions.

Although humans are able to walk without infrastructure, the transport can be enhanced through the use of roads, especially when using the human power with vehicles, such as bicycles and inline skates. Human-powered vehicles have also been developed for difficult environments, such as snow and water, by watercraft rowing and skiing; even the air can be entered with human-powered aircraft.

Animal-powered Edit
Main article: Animal-powered transport
Animal-powered transport is the use of working animals for the movement of people and commodities. Humans may ride some of the animals directly, use them as pack animals for carrying goods, or harness them, alone or in teams, to pull sleds or wheeled vehicles.
A fixed-wing aircraft, commonly called airplane, is a heavier-than-air craft where movement of the air in relation to the wings is used to generate lift. The term is used to distinguish this from rotary-wing aircraft, where the movement of the lift surfaces relative to the air generates lift. A gyroplane is both fixed-wing and rotary-wing. Fixed-wing aircraft range from small trainers and recreational aircraft to large airliners and military cargo aircraft.

Two things necessary for aircraft are air flow over the wings for lift and an area for landing. The majority of aircraft also need an airport with the infrastructure to receive maintenance, restocking, refueling and for the loading and unloading of crew, cargo and passengers. While the vast majority of aircraft land and take off on land, some are capable of take off and landing on ice, snow and calm water.

The aircraft is the second fastest method of transport, after the rocket. Commercial jets can reach up to 955 kilometres per hour (593 mph), single-engine aircraft 555 kilometres per hour (345 mph). Aviation is able to quickly transport people and limited amounts of cargo over longer distances, but incur high costs and energy use; for short distances or in inaccessible places helicopters can be used.[1] As of April 28, 2009 The Guardian article notes that, “the WHO estimates that up to 500,000 people are on planes at any time.”
Rail transport is where a train runs along a set of two parallel steel rails, known as a railway or railroad. The rails are anchored perpendicular to ties (or sleepers) of timber, concrete or steel, to maintain a consistent distance apart, or gauge. The rails and perpendicular beams are placed on a foundation made of concrete, or compressed earth and gravel in a bed of ballast. Alternative methods include monorail and maglev.

A train consists of one or more connected vehicles that operate on the rails. Propulsion is commonly provided by a locomotive, that hauls a series of unpowered cars, that can carry passengers or freight. The locomotive can be powered by steam, diesel or by electricity supplied by trackside systems. Alternatively, some or all the cars can be powered, known as a multiple unit. Also, a train can be powered by horses, cables, gravity, pneumatics and gas turbines. Railed vehicles move with much less friction than rubber tires on paved roads, making trains more energy efficient, though not as efficient as ships.

Intercity trains are long-haul services connecting cities;[3] modern high-speed rail is capable of speeds up to 350 km/h (220 mph), but this requires specially built track. Regional and commuter trains feed cities from suburbs and surrounding areas, while intra-urban transport is performed by high-capacity tramways and rapid transits, often making up the backbone of a city’s public transport. Freight trains traditionally used box cars, requiring manual loading and unloading of the cargo. Since the 1960s, container trains have become the dominant solution for general freight, while large quantities of bulk are transported by dedicated trains.
A road is an identifiable route, way or path between two or more places.[4] Roads are typically smoothed, paved, or otherwise prepared to allow easy travel;[5] though they need not be, and historically many roads were simply recognizable routes without any formal construction or maintenance.[6] In urban areas, roads may pass through a city or village and be named as streets, serving a dual function as urban space easement and route.[7]

The most common road vehicle is the automobile; a wheeled passenger vehicle that carries its own motor. Other users of roads include buses, trucks, motorcycles, bicycles and pedestrians. As of 2010, there were 1.015 billion automobiles worldwide. Road transport offers a complete freedom to road users to transfer the vehicle from one lane to the other and from one road to another according to the need and convenience. This flexibility of changes in location, direction, speed, and timings of travel is not available to other modes of transport. It is possible to provide door to door service only by road transport.

Automobiles provide high flexibility with low capacity, but require high energy and area use, and are the main source of noise and air pollution in cities; buses allow for more efficient travel at the cost of reduced flexibility.[8] Road transport by truck is often the initial and final stage of freight transport.
Water transport is movement by means of a watercraft—such as a barge, boat, ship or sailboat—over a body of water, such as a sea, ocean, lake, canal or river. The need for buoyancy is common to watercraft, making the hull a dominant aspect of its construction, maintenance and appearance.

In the 19th century the first steam ships were developed, using a steam engine to drive a paddle wheel or propeller to move the ship. The steam was produced in a boiler using wood or coal and fed through a steam external combustion engine. Now most ships have an internal combustion engine using a slightly refined type of petroleum called bunker fuel. Some ships, such as submarines, use nuclear power to produce the steam. Recreational or educational craft still use wind power, while some smaller craft use internal combustion engines to drive one or more propellers, or in the case of jet boats, an inboard water jet. In shallow draft areas, hovercraft are propelled by large pusher-prop fans. (See Marine propulsion.)

Although slow, modern sea transport is a highly efficient method of transporting large quantities of goods. Commercial vessels, nearly 35,000 in number, carried 7.4 billion tons of cargo in 2007.[9] Transport by water is significantly less costly than air transport for transcontinental shipping;[10] short sea shipping and ferries remain viable in coastal areas.
Pipeline transport sends goods through a pipe; most commonly liquid and gases are sent, but pneumatic tubes can also send solid capsules using compressed air. For liquids/gases, any chemically stable liquid or gas can be sent through a pipeline. Short-distance systems exist for sewage, slurry, water and beer, while long-distance networks are used for petroleum and natural gas.

Cable transport is a broad mode where vehicles are pulled by cables instead of an internal power source. It is most commonly used at steep gradient. Typical solutions include aerial tramway, elevators, escalator and ski lifts; some of these are also categorized as conveyor transport.

Spaceflight is transport out of Earth’s atmosphere into outer space by means of a spacecraft. While large amounts of research have gone into technology, it is rarely used except to put satellites into orbit, and conduct scientific experiments. However, man has landed on the moon, and probes have been sent to all the planets of the Solar System.

Suborbital spaceflight is the fastest of the existing and planned transport systems from a place on Earth to a distant other place on Earth. Faster transport could be achieved through part of a low Earth orbit, or following that trajectory even faster using the propulsion of the rocket to steer it.
Infrastructure is the fixed installations that allow a vehicle to operate. It consists of a way, a terminal and facilities for parking and maintenance. For rail, pipeline, road and cable transport, the entire way the vehicle travels must be built up. Air and water craft are able to avoid this, since the airway and seaway do not need to be built up. However, they require fixed infrastructure at terminals.

Terminals such as airports, ports and stations, are locations where passengers and freight can be transferred from one vehicle or mode to another. For passenger transport, terminals are integrating different modes to allow riders to interchange to take advantage of each mode’s advantages. For instance, airport rail links connect airports to the city centers and suburbs. The terminals for automobiles are parking lots, while buses and coaches can operate from simple stops.[13] For freight, terminals act as transshipment points, though some cargo is transported directly from the point of production to the point of use.

The financing of infrastructure can either be public or private. Transport is often a natural monopoly and a necessity for the public; roads, and in some countries railways and airports are funded through taxation. New infrastructure projects can have high cost, and are often financed through debt. Many infrastructure owners therefore impose usage fees, such as landing fees at airports, or toll plazas on roads. Independent of this, authorities may impose taxes on the purchase or use of vehicles. Because of poor forecasting and overestimation of passenger numbers by planners, there is frequently a benefits shortfall for transport infrastructure projects.[14]

Vehicles Edit
Main article: Vehicle

A Fiat Uno in 2008
A vehicle is a non-living device that is used to move people and goods. Unlike the infrastructure, the vehicle moves along with the cargo and riders. Unless being pulled/pushed by a cable or muscle-power, the vehicle must provide its own propulsion; this is most commonly done through a steam engine, combustion engine, electric motor, a jet engine or a rocket, though other means of propulsion also exist. Vehicles also need a system of converting the energy into movement; this is most commonly done through wheels, propellers and pressure.
Vehicles are most commonly staffed by a driver. However, some systems, such as people movers and some rapid transits, are fully automated. For passenger transport, the vehicle must have a compartment, seat, or platform for the passengers. Simple vehicles, such as automobiles, bicycles or simple aircraft, may have one of the passengers as a driver.

Operation Edit

Incheon International Airport, South Korea
Private transport is only subject to the owner of the vehicle, who operates the vehicle themselves. For public transport and freight transport, operations are done through private enterprise or by governments. The infrastructure and vehicles may be owned and operated by the same company, or they may be operated by different entities. Traditionally, many countries have had a national airline and national railway. Since the 1980s, many of these have been privatized. International shipping remains a highly competitive industry with little regulation,[15] but ports can be public owned.

Human trafficking:: types, measures and efforts, structural factors, consequence and criticism.
May 24, 2017

Trafficking of children involves the recruitment, transportation, transfer, harboring, or receipt of children for the purpose of exploitation. The commercial sexual exploitation of children can take many forms, including forcing a child into prostitution[68][69] or other forms of sexual activity or child pornography. Child exploitation may also involve forced labour or services, slavery or practices similar to slavery, servitude, the removal of organs,[70] illicit international adoption, trafficking for early marriage, recruitment as child soldiers, for use in begging or as athletes (such as child camel jockeys[71] or football players[72]).

IOM statistics indicate that a significant minority (35%) of trafficked persons it assisted in 2011 were less than 18 years of age, which is roughly consistent with estimates from previous years. It was reported in 2010 that Thailand and Brazil were considered to have the worst child sex trafficking records.[73]

Traffickers in children may take advantage of the parents’ extreme poverty. Parents may sell children to traffickers in order to pay off debts or gain income, or they may be deceived concerning the prospects of training and a better life for their children. They may sell their children into labor, sex trafficking, or illegal adoptions.

The adoption process, legal and illegal, when abused can sometimes result in cases of trafficking of babies and pregnant women from developing countries to the West.[74] In David M. Smolin’s papers on child trafficking and adoption scandals between India and the United States,[75][76] he presents the systemic vulnerabilities in the inter-country adoption system that makes adoption scandals predictable.

The United Nations Convention on the Rights of the Child at Article 34, states, “States Parties undertake to protect the child from all forms of sexual exploitation and sexual abuse”.[77] In the European Union, commercial sexual exploitation of children is subject to a directive – Directive 2011/92/EU of the European Parliament and of the Council of 13 December 2011 on combating the sexual abuse and sexual exploitation of children and child pornography.[78]

The Hague Convention on Protection of Children and Co-operation in Respect of Intercountry Adoption (or Hague Adoption Convention) is an international convention dealing with international adoption, that aims at preventing child laundering, child trafficking, and other abuses related to international adoption.[79]

The Optional Protocol on the Involvement of Children in Armed Conflict seeks to prevent forceful recruitment (e.g. by guerrilla forces) of children for use in armed conflicts.
Sex trafficking affects 4.5 million people worldwide.[81] Most victims find themselves in coercive or abusive situations from which escape is both difficult and dangerous.[82]

Trafficking for sexual exploitation was formerly thought of as the organized movement of people, usually women, between countries and within countries for sex work with the use of physical coercion, deception and bondage through forced debt. However, the Trafficking Victims Protection Act of 2000 (US),[83] does not require movement for the offence. The issue becomes contentious when the element of coercion is removed from the definition to incorporate facilitation of consensual involvement in prostitution. For example, in the United Kingdom, the Sexual Offences Act 2003 incorporated trafficking for sexual exploitation but did not require those committing the offence to use coercion, deception or force, so that it also includes any person who enters the UK to carry out sex work with consent as having been “trafficked.”[84] In addition, any minor involved in a commercial sex act in the US while under the age of 18 qualifies as a trafficking victim, even if no force, fraud or coercion is involved, under the definition of “Severe Forms of Trafficking in Persons” in the US Trafficking Victims Protection Act of 2000.[83]

Sexual trafficking includes coercing a migrant into a sexual act as a condition of allowing or arranging the migration. Sexual trafficking uses physical or sexual coercion, deception, abuse of power and bondage incurred through forced debt. Trafficked women and children, for instance, are often promised work in the domestic or service industry, but instead are sometimes taken to brothels where they are required to undertake sex work, while their passports and other identification papers confiscated. They may be beaten or locked up and promised their freedom only after earning – through prostitution – their purchase price, as well as their travel and visa costs.[85][86]

Forced marriage Edit
Main article: Forced marriage
A forced marriage is a marriage where one or both participants are married without their freely given consent.[87] Servile marriage is defined as a marriage involving a person being sold, transferred or inherited into that marriage.[88] According to ECPAT, “Child trafficking for forced marriage is simply another manifestation of trafficking and is not restricted to particular nationalities or countries”.[3]

A forced marriage qualifies as a form of human trafficking in certain situations. If a woman is sent abroad, forced into the marriage and then repeatedly compelled to engage in sexual conduct with her new husband, then her experience is that of sex trafficking. If the bride is treated as a domestic servant by her new husband and/or his family, then this is a form of labor trafficking.
Labour trafficking is the movement of persons for the purpose of forced labor and services.[90] It may involve bonded labor, involuntary servitude, domestic servitude, and child labor.[90] Labor trafficking happens most often within the domain of domestic work, agriculture, construction, manufacturing and entertainment; and migrant workers and indigenous people are especially at risk of becoming victims.[81]

Trafficking for organ trade Edit
Trafficking in organs is a form of human trafficking. It can take different forms. In some cases, the victim is compelled into giving up an organ. In other cases, the victim agrees to sell an organ in exchange of money/goods, but is not paid (or paid less). Finally, the victim may have the organ removed without the victim’s knowledge (usually when the victim is treated for another medical problem/illness – real or orchestrated problem/illness). Migrant workers, homeless persons, and illiterate persons are particularly vulnerable to this form of exploitation. Trafficking of organs is an organized crime, involving several offenders:[91]

the recruiter
the transporter
the medical staff
the middlemen/contractors
the buyers
Trafficking for organ trade often seeks kidneys. Trafficking in organs is a lucrative trade because in many countries the waiting lists for patients who need transplants are very long.
There are many different estimates of how large the human trafficking and sex trafficking industries are. According to scholar Kevin Bales, author of Disposable People (2004), estimates that as many as 27 million people are in “modern-day slavery” across the globe.[93][94] In 2008, the U.S. Department of State estimates that 2 million children are exploited by the global commercial sex trade.[95] In the same year, a study classified 12.3 million individuals worldwide as “forced laborers, bonded laborers or sex-trafficking victims.” Approximately 1.39 million of these individuals worked as commercial sex slaves, with women and girls comprising 98%, of the 1.36 million.[96]

The enactment of the Victims of Trafficking and Violence Protection Act (TVPA) in 2000 by the United States Congress and its subsequent re-authorizations established the Department of State’s Office to Monitor and Combat Trafficking in Persons, which engages with foreign governments to fight human trafficking and publishes a Trafficking in Persons Report annually. The Trafficking in Persons Report evaluates each country’s progress in anti-trafficking and places each country onto one of three tiers based on their governments’ efforts to comply with the minimum standards for the elimination of trafficking as prescribed by the TVPA.[97] However, questions have been raised by critical anti-trafficking scholars about the basis of this tier system, its heavy focus on compliance with state department protocols, and its failure to consider “risk” and the likely prevalence of trafficking when rating the efforts of diverse countries.[98]

In particular, there were three main components of the TVPA, commonly called the three P’s:

PROTECTION: The TVPA increased the US Government’s efforts to protect trafficked foreign national victims including, but not limited to: Victims of trafficking, many of whom were previously ineligible for government assistance, were provided assistance; and a non-immigrant status for victims of trafficking if they cooperated in the investigation and prosecution of traffickers (T-Visas, as well as providing other mechanisms to ensure the continued presence of victims to assist in such investigations and prosecutions).

PROSECUTION: The TVPA authorized the US Government to strengthen efforts to prosecute traffickers including, but not limited to: Creating a series of new crimes on trafficking, forced labor, and document servitude that supplemented existing limited crimes related to slavery and involuntary servitude; and recognizing that modern-day slavery takes place in the context of fraud and coercion, as well as force, and is based on new clear definitions for both trafficking into sexual exploitation and labor exploitation: Sex trafficking was defined as, “a commercial sex act that is induced by force, fraud, or coercion, or in which the person induced to perform such an act has not attained 18 years of age”. Labor trafficking was defined as, “the recruitment, harboring, transportation, provision, or obtaining of a person for labor or services, through the use of force, fraud, or coercion for the purpose of subjection to involuntary servitude, peonage, debt bondage, or slavery”.

PREVENTION: The TVPA allowed for increased prevention measures including: Authorizing the US Government to assist foreign countries with their efforts to combat trafficking, as well as address trafficking within the United States, including through research and awareness-raising; and providing foreign countries with assistance in drafting laws to prosecute trafficking, creating programs for trafficking victims, and assistance with implementing effective means of investigation.
Secretary of State Hillary Rodham Clinton later identified a fourth P, “partnership”, in 2009 to serve as a, “pathway to progress in the effort against modern-day slavery.”
A complex set of factors fuel sex trafficking, including poverty, unemployment, social norms that discriminate against women, commercial demand for sex, institutional challenges, and globalization.

Poverty and globalization Edit
Poverty and lack of educational and economic opportunities in one’s hometown may lead women to voluntarily migrate and then be involuntarily trafficked into sex work.[101][102] As globalization opened up national borders to greater exchange of goods and capital, labor migration also increased. Less wealthy countries have fewer options for livable wages. The economic impact of globalization pushes people to make conscious decisions to migrate and be vulnerable to trafficking. Gender inequalities that hinder women from participating in the formal sector also push women into informal sectors.[103]

Long waiting lists for organs in the United States and Europe created a thriving international black market. Traffickers harvest organs, particularly kidneys, to sell for large profit and often without properly caring for or compensating the victims. Victims often come from poor, rural communities and see few other options than to sell organs illegally.[104] Wealthy countries’ inability to meet organ demand within their own borders perpetuates trafficking. By reforming their internal donation system, Iran achieved a surplus of legal donors and provides an instructive model for eliminating both organ trafficking and -shortage.[105]

Globalization and the rise of Internet technology has also facilitated sex trafficking. Online classified sites and social networks such as Craigslist have been under intense scrutiny for being used by johns and traffickers in facilitating sex trafficking and sex work in general. Traffickers use explicit sites and underground sites (e.g. Craigslist, Backpage, MySpace) to market, recruit, sell, and exploit females. Facebook, Twitter, and other social networking sites are suspected for similar uses. For example, Randal G. Jennings was convicted of sex trafficking five underage girls by forcing them to advertise on Craigslist and driving them to meet the customers.[citation needed] According to the National Center for Missing and Exploited Children, online classified ads reduce the risks of finding prospective customers.[106] Studies have identified the Internet as the single biggest facilitator of commercial sex trade, although it is difficult to ascertain which women advertised are sex trafficking victims.[107] Traffickers and pimps use the Internet to recruit minors, since Internet and social networking sites usage have significantly increased especially among children.[108]

Organized criminals can generate up to several thousand dollars per day from one trafficked girl, and the Internet has further increased profitability of sex trafficking and child trafficking. With faster access to a wider clientele, more sexual encounters can be scheduled.[109] Victims and clients, according to a New York City report on sex trafficking in minors, increasingly use the Internet to meet customers. Because of protests, Craigslist has since closed its adult services section. According to authorities, Backpage is now the main source for advertising trafficking victims.[110] Investigators also frequently browse online classified ads to identify potential underage girls who are trafficked.
While globalization fostered new technologies that may exacerbate sex trafficking, technology can also be used to assist law enforcement and anti-trafficking efforts. A study was done on online classified ads surrounding the Super Bowl. A number of reports have noticed increase in sex trafficking during previous years of the Super Bowl.[111] For the 2011 Super Bowl held in Dallas, Texas, the Backpage for Dallas area experienced a 136% increase on the number of posts in the Adult section on Super Bowl Sunday, where as Sundays typically have the lowest amount of posts. Researchers analyzed the most salient terms in these online ads, which suggested that many escorts were traveling across state lines to Dallas specifically for the Super Bowl, and found that the self-reported ages were higher than usual. Twitter was another social networking platform studied for detecting sex trafficking. Digital tools can be used to narrow the pool of sex trafficking cases, albeit imperfectly and with uncertainty.[112]

However, there has been no evidence found actually linking the Super Bowl – or any other sporting event – to increased trafficking or prostitution.[113][114]

Political and institutional challenges Edit
Corrupt and inadequately trained police officers can be complicit in sex trafficking and/or commit violence against sex workers, including sex trafficked victims.[115]

Anti-trafficking agendas from different groups can also be in conflict. In the movement for sex workers rights, sex workers establish unions and organizations, which seek to eliminate trafficking themselves. However, law enforcement also seek to eliminate trafficking and to prosecute trafficking, and their work may infringe on sex workers’ rights and agency. For example, the sex workers union DMSC (Durbar Mahila Samanwaya Committee) in Kolkata, India, has “self-regulatory boards” (SRBs) that patrol the red light districts and assist girls who are underage or trafficked. The union opposes police intervention and interferes with police efforts to bring minor girls out of brothels, on the grounds that police action might have an adverse impact on non-trafficked sex workers, especially because police officers in many places are corrupt and violent in their operations.[115] Critics argue that since sex trafficking is an economic and violent crime, it calls for law enforcement to intervene and prevent violence against victims.

Criminalization of sex work also may foster the underground market for sex work and enable sex trafficking.[101]

Difficult political situations such as civil war and social conflict are push factors for migration and trafficking. A study reported that larger countries, the richest and the poorest countries, and countries with restricted press freedom are likely to engage in more sex trafficking. Specifically, being in a transitional economy made a country nineteen times more likely to be ranked in the highest trafficking category, and gender inequalities in a country’s labor market also correlated with higher trafficking rates.[116]

An annual US State Department report in June 2013 cited Russia and China as among the worst offenders in combatting forced labour and sex trafficking, raising the possibility of US sanctions being leveraged against these countries.[117] In 1997 alone as many as 175,000 young women from Russia, as well as the former Soviet Union, were sold as commodities in the sex markets of the developed countries in Europe and the Americas.
Abolitionists who seek an end to sex trafficking explain the nature of sex trafficking as an economic supply and demand model. In this model, male demand for prostitutes leads to a market of sex work, which, in turn, fosters sex trafficking, the illegal trade and coercion of people into sex work, and pimps and traffickers become ‘distributors’ who supply people to be sexually exploited. The demand for sex trafficking can also be facilitated by some pimps’ and traffickers’ desire for women whom they can exploit as workers because they do not require wages, safe working circumstances, and agency in choosing customers.
Sex trafficking victims face threats of violence from many sources, including customers, pimps, brothel owners, madams, traffickers, and corrupt local law enforcement officials. Raids as an anti-sex trafficking measure have to potential to help, and also to harm sex trafficked victims. Because of their potentially complicated legal status and their potential language barriers, the arrest or fear of arrest creates stress and other emotional trauma for trafficking victims. Victims may also experience physical violence from law enforcement during raids.[121][122] The challenges facing victims often continue of course, after their experience of “rescue” or removal from coercive sexual exploitation. In addition to coping with their past traumatic experiences, former trafficking victims often experience social alienation in the host and home countries. Stigmatization, social exclusion, and intolerance often make it difficult for former victims to integrate into their host community, or to reintegrate into their former community. Accordingly, one of the central aims of protection assistance, is the promotion of (re)integration.[123][56] Too often however, governments and large institutional donors offer little funding to support the provision of assistance and social services to former trafficking victims. As the victims are also pushed into drug trafficking, many of them face criminal sanctions also.[124]

Psychological Edit
Short-term impact – psychological coercion Edit
The use of coercion by perpetrators and traffickers involves the use of extreme control. Perpetrators expose the victim to high amounts of psychological stress induced by threats, fear, and physical and emotional violence. Tactics of coercion are reportedly used in three phases of trafficking: recruitment, initiation, and indoctrination.[125] During the initiation phase, traffickers use foot-in-the-door techniques of persuasion to lead their victims into various trafficking industries. This manipulation creates an environment where the victim becomes completely dependent upon the authority of the trafficker.[125] Traffickers take advantage of family dysfunction, homelessness, and history of childhood abuse to psychologically manipulate women and children into the trafficking industry.[126]

One form of psychological coercion particularly common in cases of sex trafficking and forced prostitution is Stockholm syndrome. Many women entering into the sex trafficking industry are minors whom have already experienced prior sexual abuse.[127] Traffickers take advantage of young girls by luring them into the business through force and coercion, but more often through false promises of love, security, and protection. This form of coercion works to recruit and initiate the victim into the life of a sex worker, while also reinforcing a “trauma bond”, also known as Stockholm syndrome. Stockholm syndrome is a psychological response where the victim becomes attached to her perpetrator.[127][128]

The goal of a trafficker is to turn a human being into a slave. To do this, perpetrators employ tactics that can lead to the psychological consequence of learned helplessness for the victims, where they sense that they no longer have any autonomy or control over their lives.[126] Traffickers may hold their victims captive, expose them to large amounts of alcohol or use drugs, keep them in isolation, or withhold food or sleep.[126] During this time the victim often begins to feel the onset of depression, guilt and self-blame, anger and rage, and sleep disturbances, PTSD, numbing, and extreme stress. Under these pressures, the victim can fall into the hopeless mental state of learned helplessness.
For victims of specifically trafficked for the purpose of forced prostitution and sexual slavery, initiation into the trade is almost always characterized by violence.[126] Traffickers hunt down their victims and employ practices of sexual abuse, torture, brainwashing, repeated rape and physical assault until the victim submits to his or her fate as a sexual slave. Victims experience verbal threats, social isolation, and intimidation before they accept their role as a prostitute.[131]

For those enslaved in situations of forced labor, learned helplessness can also manifest itself through the trauma of living as a slave. Reports indicate that captivity for the person and financial gain of their owners adds additional psychological trauma. Victims are often cut off from all forms of social connection, as isolation allows the perpetrator to destroy the victim’s sense of self and increase his or her dependence on the perpetrator.[125]

Long-term impact Edit
Human trafficking victims may experience complex trauma as a result of repeated cases of intimate relationship trauma over long periods of time including, but not limited to, sexual abuse, domestic violence, forced prostitution, or gang rape. Complex trauma involves multifaceted conditions of depression, anxiety, self-hatred, dissociation, substance abuse, self-destructive behaviors, medical and somatic concerns, despair, and revictimization. Psychology researchers report that, although similar to posttraumatic stress disorder (PTSD), Complex trauma is more expansive in diagnosis because of the effects of prolonged trauma.[132]

Victims of sex trafficking often get “branded”[133] by their traffickers or pimps. These tattoos usually consist of bar codes or the trafficker’s name or rules. Even if a victim escapes their trafficker’s control or gets rescued, these tattoos are painful reminders of their past and results in emotional distress. To get these tattoos removed or covered-up can cost hundreds of dollars. [134]

Psychological reviews have shown that the chronic stress experienced by many victims of human trafficking can compromise the immune system.[126] Several studies found that chronic stressors (like trauma or loss) suppressed cellular and humoral immunity.[129] Victims may develop STDs and HIV/AIDS.[135] Perpetrators frequently use substance abuse as a means to control their victims, which leads to compromised health, self-destructive behavior, and long-term physical harm.[136] Furthermore, victims have reported treatment similar to torture, where their bodies are broken and beaten into submission.[136][137]

Children are especially vulnerable to these developmental and psychological consequences of trafficking due to their age. In order to gain complete control of the child, traffickers often destroy physical and mental health of the children through persistent physical and emotional abuse.[138] Victims experience severe trauma on a daily basis that devastates the healthy development of self-concept, self-worth, biological integrity, and cognitive functioning.[139] Children who grow up in constant environments of exploitation frequently exhibit antisocial behavior, over-sexualized behavior, self-harm, aggression, distrust of adults, dissociative disorders, substance abuse, complex trauma, and attention deficit disorders.[128][138][139][140] Stockholm syndrome is also a common problem for girls while they are trafficked, which can hinder them from both trying to escape, and moving forward in psychological recovery programs.
Although 98% of the sex trade is composed of women and girls[137] there is an effort to gather empirical evidence about the psychological impact of abuse common in sex trafficking upon young boys.[139][141] Boys often will experience forms of post-traumatic stress disorder, but also additional stressors of social stigma of homosexuality associated with sexual abuse for boys, and externalization of blame, increased anger, and desire for revenge.
Sex trafficking increases the risk of contracting HIV/AIDS.[143] The HIV/AIDS pandemic can be both a cause and a consequence of sex trafficking. On one hand, child-prostitutes are sought by customers because they are perceived as being less likely to be HIV positive, and this demand leads to child sex trafficking. On the other hand, trafficking leads to the proliferation of HIV, because victims, being vulnerable and often young/inexperienced, cannot protect themselves properly, and get infected.[144]

Economic impacts Edit
According to estimates from the International Labour Organization (ILO), every year the human trafficking industry generates 32 billion USD, half of which ($15.5 billion) is made in industrialized countries, and a third of which ($9.7 billion) is made in Asia.[145] A 2011 paper published in Human Rights Review, “Sex Trafficking: Trends, Challenges and Limitations of International Law”, notes that, since 2000, the number of sex-trafficking victims has risen while costs associated with trafficking have declined: “Coupled with the fact that trafficked sex slaves are the single most profitable type of slave, costing on average $1,895 each but generating $29,210 annually, [there are] stark predictions about the likely growth in commercial sex slavery in the future.”[96] Sex trafficking victims rarely get a share of the money that they make through coerced sex work, which further keeps them oppressed.

Both the human trafficking discourse and the actions undertaken by the anti-human traffickers have been criticized by some scholars[148][149] and journalists.[150] The criticism touches upon three main themes: 1) statistics and data on human trafficking; 2) the concept itself; 3) the anti-trafficking measures.

Problems with statistics and data Edit
Numerous NGOs and governmental agencies produce estimates and specific statistics on the numbers of potential and actual victims of trafficking.[151] According to the critics, these figures rarely have identifiable sources or transparent methodologies behind them and in most (if not all) instances, they are mere guesses.[152][153] Scholars argue that this is a result of the fact that it is impossible to produce any meaningful statistics on a reportedly illegal and covert phenomenon happening in the shadow economy.[148][154][155] Others argue that many of these statistics are inflated to aid advocacy of anti-trafficking NGOs and the anti-trafficking policies of governments. Because of the definition of trafficking as a process (not a singly defined act) and the fact that it is a dynamic phenomenon with constantly shifting patterns relating to economic circumstances, much of the statistical evaluation is flawed.[156]

A 2012 article in the International Communication Gazette examined the effect of two communication theories (agenda-building and agenda-setting) on media coverage on human trafficking in the United States and Britain. The article analyzed four newspapers including the Guardian and the Washington Post and categorized the content into various categories. Overall, the article found that sex trafficking was the most reported form of human trafficking by the newspapers that were analyzed (p. 154). Many of the other stories on trafficking were non-specific.[157]

Problems with the concept Edit
According to some scholars, the very concept of human trafficking is murky and misleading.[148] It has been argued that while human trafficking is commonly seen as a monolithic crime, in reality it is an act of illegal migration that involves various different actions: some of them may be criminal or abusive, but others often involve consent and are legal.[148] Laura Agustin argues that not everything that might seem abusive or coercive is considered as such by the migrant. For instance, she states that: ‘would-be travellers commonly seek help from intermediaries who sell information, services and documents. When travellers cannot afford to buy these outright, they go into debt’.[154] One scholar says that while these debts might indeed be on very harsh conditions, they are usually incurred on a voluntary basis.[148]

The critics of the current approaches to trafficking say that a lot of the violence and exploitation faced by illegal migrants derives precisely from the fact that their migration and their work are illegal and not primarily because of trafficking.[158] Tara McCormack, a lecturer in international relations at Brunel University, has opined in Spiked magazine that the whole trafficking discourse can actually be detrimental to the interests of migrants as it denies them agency and as it depoliticizes debates on migration.[159]

The international Save the Children organization also stated: “… The issue, however, gets mired in controversy and confusion when prostitution too is considered as a violation of the basic human rights of both adult women and minors, and equal to sexual exploitation per se. … trafficking and prostitution become conflated with each other. …. On account of the historical conflation of trafficking and prostitution both legally and in popular understanding, an overwhelming degree of effort and interventions of anti-trafficking groups are concentrated on trafficking into prostitution.”[

Human trafficking is the trade of humans, most commonly for the purpose of forced labour, sexual slavery, or commercial sexual exploitation for the trafficker or others.[1][2] This may encompass providing a spouse in the context of forced marriage,[3][4][5] or the extraction of organs or tissues,[6][7] including for surrogacy and ova removal.[8] Human trafficking can occur within a country or trans-nationally. Human trafficking is a crime against the person because of the violation of the victim’s rights of movement through coercion and because of their commercial exploitation. Human trafficking is the trade in people, especially women and children, and does not necessarily involve the movement of the person from one place to another.

According to the International Labour Organization (ILO), forced labor alone (one component of human trafficking) generates an estimated $150 billion in profits per annum as of 2014.[9] In 2012, the I.L.O. estimated that 21 million victims are trapped in modern-day slavery. Of these, 14.2 million (68%) were exploited for labor, 4.5 million (22%) were sexually exploited, and 2.2 million (10%) were exploited in state-imposed forced labor.[10]

Human trafficking is thought to be one of the fastest-growing activities of trans-national criminal organizations.[11]

Human trafficking is condemned as a violation of human rights by international conventions. In addition, human trafficking is subject to a directive in the European Union.
Although human trafficking can occur at local levels, it has transnational implications, as recognized by the United Nations in the Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children (also referred to as the Trafficking Protocol or the Palermo Protocol), an international agreement under the UN Convention against Transnational Organized Crime (CTOC) which entered into force on 25 December 2003. The protocol is one of three which supplement the CTOC.[13] The Trafficking Protocol is the first global, legally binding instrument on trafficking in over half a century, and the only one with an agreed-upon definition of trafficking in persons. One of its purposes is to facilitate international cooperation in investigating and prosecuting such trafficking. Another is to protect and assist human trafficking’s victims with full respect for their rights as established in the Universal Declaration of Human Rights. The Trafficking Protocol, which now has 169 parties,[14] defines human trafficking as:

(a) […] the recruitment, transportation, transfer, harbouring or receipt of persons, by means of threat or use of force or other forms of coercion, of abduction, of fraud, of deception, of the abuse of power or of a position of vulnerability or of the giving or receiving of payments or benefits to achieve the consent of a person having control over another person, for the purpose of exploitation. Exploitation shall include, at a minimum, the exploitation of the prostitution of others or other forms of sexual exploitation, forced labour or services, slavery or practices similar to slavery, servitude or the removal, manipulation or implantation of organs;

(b) The consent of a victim of trafficking in persons to the intended exploitation set forth in sub-paragraph (a) of this article shall be irrelevant where any of the means set forth in subparagraph (a) have been used;
(c) The recruitment, transportation, transfer, harbouring or receipt of a child for the purpose of exploitation shall be considered “trafficking in persons” even if this does not involve any of the means set forth in sub-paragraph (a) of this article;
(d) “Child” shall mean any person under eighteen years of age.[15]

Revenue Edit
In 2014, the International Labour Organization estimated $150 billion in annual profit is generated from forced labor alone.[16]

The average cost of a human trafficking victim today is USD $90 whereas the average slave in 1800 America cost the equivalent to USD $40,000.
Human trafficking differs from people smuggling, which involves a person voluntarily requesting or hiring another individual to covertly transport them across an international border, usually because the smuggled person would be denied entry into a country by legal channels. Though illegal, there may be no deception or coercion involved. After entry into the country and arrival at their ultimate destination, the smuggled person is usually free to find their own way. According to the International Centre for Migration Policy Development (ICMPD), people smuggling is a violation of national immigration laws of the destination country, and does not require violations of the rights of the smuggled person. Human trafficking, on the other hand, is a crime against a person because of the violation of the victim’s rights through coercion and exploitation.[18] Unlike most cases of people smuggling, victims of human trafficking are not permitted to leave upon arrival at their destination.

While smuggling requires travel, trafficking does not. Trafficked people are held against their will through acts of coercion, and forced to work for or provide services to the trafficker or others. The work or services may include anything from bonded or forced labor to commercial sexual exploitation.[1][2] The arrangement may be structured as a work contract, but with no or low payment, or on terms which are highly exploitative. Sometimes the arrangement is structured as debt bondage, with the victim not being permitted or able to pay off the debt.

Bonded labor, or debt bondage, is probably the least known form of labor trafficking today, and yet it is the most widely used method of enslaving people. Victims become “bonded” when their labor, the labor they themselves hired and the tangible goods they bought are demanded as a means of repayment for a loan or service in which its terms and conditions have not been defined or in which the value of the victims’ services is not applied toward the liquidation of the debt. Generally, the value of their work is greater than the original sum of money “borrowed.”[19]

Forced labor is a situation in which victims are forced to work against their own will under the threat of violence or some other form of punishment; their freedom is restricted and a degree of ownership is exerted. Men are at risk of being trafficked for unskilled work, which globally generates 31 billion USD according to the International Labour Organization.[20] Forms of forced labor can include domestic servitude, agricultural labor, sweatshop factory labor, janitorial, food service and other service industry labor, and begging.[19] Some of the products that can be produced by forced labor are: clothing, cocoa, bricks, coffee, cotton, and gold.[21]

The International Organization for Migration (IOM), the single largest global provider of services to victims of trafficking, reports receiving an increasing number of cases in which victims were subjected to forced labor. A 2012 study observes that “… 2010 was particularly notable as the first year in which IOM assisted more victims of labor trafficking than those who had been trafficked for purposes of sexual exploitation.”[22]

Child labour is a form of work that may be hazardous to the physical, mental, spiritual, moral, or social development of children and can interfere with their education. According to the International Labour Organization, the global number of children involved in child labor has fallen during the past decade – it has declined by one third, from 246 million in 2000 to 168 million children in 2012.[23] Sub-Saharan Africa is the region with the highest incidence of child labour, while the largest numbers of child-workers are found in Asia and the Pacific.
The UN Office on Drugs and Crime (UNODC) has further assisted many non-governmental organizations in their fight against human trafficking. The 2006 armed conflict in Lebanon, which saw 300,000 domestic workers from Sri Lanka, Ethiopia and the Philippines jobless and targets of traffickers, led to an emergency information campaign with NGO Caritas Migrant to raise human-trafficking awareness. Additionally, an April 2006 report, Trafficking in Persons: Global Patterns, helped to identify 127 countries of origin, 98 transit countries and 137 destination countries for human trafficking. To date, it is the second most frequently downloaded UNODC report. Continuing into 2007, UNODC supported initiatives like the Community Vigilance project along the border between India and Nepal, as well as provided subsidy for NGO trafficking prevention campaigns in Bosnia and Herzegovina and Croatia.[25] Public service announcements have also proved useful for organizations combating human trafficking. In addition to many other endeavors, UNODC works to broadcast these announcements on local television and radio stations across the world. By providing regular access to information regarding human-trafficking, individuals are educated how to protect themselves and their families from being exploited.

The United Nations Global Initiative to Fight Human Trafficking (UN.GIFT) was conceived to promote the global fight on human trafficking, on the basis of international agreements reached at the UN. UN.GIFT was launched in March 2007 by UNODC with a grant made on behalf of the United Arab Emirates. It is managed in cooperation with the International Labour Organization (ILO); the International Organization for Migration (IOM); the UN Children’s Fund (UNICEF); the Office of the High Commissioner for Human Rights (OHCHR); and the Organization for Security and Co-operation in Europe (OSCE).

Within UN.GIFT, UNODC launched a research exercise to gather primary data on national responses to trafficking in persons worldwide. This exercise resulted in the publication of the Global Report on Trafficking in Persons in February 2009. The report gathers official information for 155 countries and territories in the areas of legal and institutional framework, criminal justice response and victim assistance services.[23] UN.GIFT works with all stakeholders — governments, business, academia, civil society and the media — to support each other’s work, create new partnerships, and develop effective tools to fight human trafficking.

The Global Initiative is based on a simple principle: human trafficking is a crime of such magnitude and atrocity that it cannot be dealt with successfully by any government alone. This global problem requires a global, multi-stakeholder strategy that builds on national efforts throughout the world. To pave the way for this strategy, stakeholders must coordinate efforts already underway, increase knowledge and awareness, provide technical assistance, promote effective rights-based responses, build capacity of state and non-state stakeholders, foster partnerships for joint action, and above all, ensure that everybody takes responsibility for this fight. By encouraging and facilitating cooperation and coordination, UN.GIFT aims to create synergies among the anti-trafficking activities of UN agencies, international organizations and other stakeholders to develop the most efficient and cost-effective tools and good practices.[26]

UN.GIFT aims to mobilize state and non-state actors to eradicate human trafficking by reducing both the vulnerability of potential victims and the demand for exploitation in all its forms, ensuring adequate protection and support to those who fall victim, and supporting the efficient prosecution of the criminals involved, while respecting the fundamental human rights of all persons. In carrying out its mission, UN.GIFT will increase the knowledge and awareness on human trafficking, promote effective rights-based responses, build capacity of state and non-state actors, and foster partnerships for joint action against human trafficking. For more information view the UN.GIFT Progress Report 2009.[26][27] UNODC efforts to motivate action launched the Blue Heart Campaign Against Human Trafficking on 6 March 2009,[28] which Mexico launched its own national version of in April 2010.[29][30] The campaign encourages people to show solidarity with human trafficking victims by wearing the blue heart, similar to how wearing the red ribbon promotes transnational HIV/AIDS awareness.[31] On 4 November 2010, U.N. Secretary-General Ban Ki-moon launched the United Nations Voluntary Trust Fund for Victims of Trafficking in Persons to provide humanitarian, legal and financial aid to victims of human trafficking with the aim of increasing the number of those rescued and supported, and broadening the extent of assistance they receive.[32]

In December 2012, UNODC published the new edition of the Global Report on Trafficking in Persons.[33] The Global Report on Trafficking in Persons 2012 has revealed that 27 per cent of all victims of human trafficking officially detected globally between 2007 and 2010 are children, up 7 per cent from the period 2003 to 2006.

The Global Report recorded victims of 136 different nationalities detected in 118 countries between 2007 and 2010, during which period, 460 different flows were identified. Around half of all trafficking took place within the same region with 27 per cent occurring within national borders. One exception is the Middle East, where most detected victims are East and South Asians. Trafficking victims from East Asia have been detected in more than 60 countries, making them the most geographically dispersed group around the world. There are significant regional differences in the detected forms of exploitation. Countries in Africa and in Asia generally intercept more cases of trafficking for forced labour, while sexual exploitation is somewhat more frequently found in Europe and in the Americas. Additionally, trafficking for organ removal was detected in 16 countries around the world.The Report raises concerns about low conviction rates – 16 per cent of reporting countries did not record a single conviction for trafficking in persons between 2007 and 2010. As of November 2015, 169 countries have ratified the United Nations Trafficking in Persons Protocol, of which UNODC is the guardian.[14] Significant progress has been made in terms of legislation: as of 2012, 83 per cent of countries had a law criminalizing trafficking in persons in accordance with the Protocol.
In 2002, Derek Ellerman and Katherine Chon founded a non-government organization called Polaris Project to combat human trafficking. In 2007, Polaris instituted the National Human Trafficking Resource Center (NHTRC) where[35] callers can report tips and receive information on human trafficking.[36] Polaris’ website and hotline informs the public about where cases of suspected human trafficking have occurred within the United States. The website records calls on a map.[37]

In 2007, the U.S. Senate designated 11 January as a National Day of Human Trafficking Awareness in an effort to raise consciousness about this global, national and local issue.[38] In 2010, 2011, 2012 and 2013, President Barack Obama proclaimed January as National Slavery and Human Trafficking Prevention Month.[39] Along with these initiatives libraries across the United States are beginning to contribute to human trafficking awareness. Slowly, libraries are turning into educational centers for those who are not aware of this issue. They are collaborating with other organizations to train staff members to spot human trafficking victims and find ways to help them.[40]

In 2014, DARPA funded the Memex program with the explicit goal of combating human trafficking via domain-specific search.[41] The advanced search capacity, including its ability to reach into the dark web has already allowed for prosecution of human trafficking cases.[42]

Because of its size and the access to its large airport, Atlanta, Georgia is known as the core of trafficking in the United States. A 2014 study by Urban Institute showed that some traffickers, or “pimps”, in Atlanta grossed over $32,000 in one week.[43]

Council of Europe Edit
On 3 May 2005, the Committee of Ministers adopted the Council of Europe Convention on Action against Trafficking in Human Beings (CETS No. 197).[44] The Convention was opened for signature in Warsaw on 16 May 2005 on the occasion of the 3rd Summit of Heads of State and Government of the Council of Europe. On 24 October 2007, the Convention received its tenth ratification thereby triggering the process whereby it entered into force on 1 February 2008. As of May 2016, the Convention has been ratified by 46 states, with another one having signed but not yet ratified.[45]

While other international instruments already exist in this field, the Council of Europe Convention, the first European treaty in this field, is a comprehensive treaty focusing mainly on the protection of victims of trafficking and the safeguard of their rights. It also aims to prevent trafficking and to prosecute traffickers. In addition, the Convention provides for the setting up of an effective and independent monitoring mechanism capable of controlling the implementation of the obligations contained in the Convention.

The Convention is not restricted to Council of Europe member states; non-member states and the European Union also have the possibility of becoming Party to the Convention. In 2013 Belarus became the first non-Council of Europe member state to accede to the Convention.[46][47]

The Convention established a Group of Experts on Action against Trafficking in Human Beings (GRETA) which monitors the implementation of the Convention through country reports. As of 1 March 2013, GRETA has published 17 country reports.[48]

Complementary protection against sex trafficking of children is ensured through the Council of Europe Convention on the Protection of Children against Sexual Exploitation and Sexual Abuse (signed in Lanzarote, 25 October 2007). The Convention entered into force on 1 July 2010.[49] As of May 2016, the Convention has been ratified by 41 states, with another 6 states having signed but not yet ratified.[50]

In addition, the European Court of Human Rights of the Council of Europe in Strasbourg has passed judgments concerning trafficking in human beings which violated obligations under the European Convention on Human Rights: Siliadin v. France,[51] judgment of 26 July 2005, and Rantsev v. Cyprus and Russia,[52] judgment of 7 January 2010.

Organization for Security and Cooperation in Europe Edit
Main article: Organization for Security and Co-operation in Europe
In 2003, the OSCE established an anti-trafficking mechanism aimed at raising public awareness of the problem and building the political will within participating states to tackle it effectively.

The OSCE actions against human trafficking are coordinated by the Office of the Special Representative for Combating the Traffic of Human Beings.[53] In January 2010, Maria Grazia Giammarinaro became the OSCE Special Representative and Co-ordinator for Combating Trafficking in Human Beings. Dr. Giammarinaro (Italy) has been a judge at the Criminal Court of Rome since 1991. She served from 2006 until 2009 in the European Commission’s Directorate-General for Justice, Freedom and Security in Brussels, where she was responsible for work to combat human trafficking and sexual exploitation of children, as well as for penal aspects of illegal immigration within the unit dealing with the fight against organized crime. During this time, she co-ordinated the Group of Experts on Trafficking in Human Beings of the European Commission. From 2001 to 2006 she was a judge for preliminary investigation in the Criminal Court of Rome. Prior to that, from 1996 she was Head of the Legislative Office and Adviser to the Minister for Equal Opportunities. From 2006 to December 2009 the office was headed by Eva Biaudet, a former Member of Parliament and Minister of Health and Social Services in her native Finland.[citation needed]

The activities of the Office of the Special Representative range from training law enforcement agencies to tackle human trafficking to promoting policies aimed at rooting out corruption and organised crime. The Special Representative also visits countries and can, on their request, support the formation and implementation of their anti-trafficking policies. In other cases the Special Representative provides advice regarding implementation of the decisions on human trafficking, and assists governments, ministers and officials to achieve their stated goals of tackling human trafficking.[citation needed]
In India, the trafficking in persons for commercial sexual exploitation, forced labor, forced marriages and domestic servitude is considered an organized crime. The Government of India applies the Criminal Law (Amendment) Act 2013, active from 3 February 2013, as well as Section 370 and 370A IPC, which defines human trafficking and “provides stringent punishment for human trafficking; trafficking of children for exploitation in any form including physical exploitation; or any form of sexual exploitation, slavery, servitude or the forced removal of organs.” Additionally, a Regional Task Force implements the SAARC Convention on the prevention of Trafficking in Women and Children.[54]

Shri R.P.N.Singh, India’s Minister of State for Home Affairs, launched a government web portal, the Anti Human Trafficking Portal, on 20 February 2014. The official statement explained that the objective of the on-line resource is for the “sharing of information across all stakeholders, States/UTs[Union Territories] and civil society organizations for effective implementation of Anti Human Trafficking measures.”[54] The key aims of the portal are:

Aid in the tracking of cases with inter-state ramifications.
Provide comprehensive information on legislation, statistics, court judgements, United Nations Conventions, details of trafficked people and traffickers and rescue success stories.
Provide connection to “Trackchild”, the National Portal on Missing Children that is operational in many states.[54]
Also on 20 February, the Indian government announced the implementation of a Comprehensive Scheme that involves the establishment of Integrated Anti Human Trafficking Units (AHTUs) in 335 vulnerable police districts throughout India, as well as capacity building that includes training for police, prosecutors and judiciary. As of the announcement, 225 Integrated AHTUs had been made operational, while 100 more AHTUs were proposed for the forthcoming financial year.[54]

The Anti-trafficking Policy Index Edit
The ‘3P Anti-trafficking Policy Index’ measures the effectiveness of government policies to fight human trafficking based on an evaluation of policy requirements prescribed by the United Nations Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children (2000).[55]

The policy level is evaluated using a five-point scale, where a score of five indicates the best policy practice, while score 1 is the worst. This scale is used to analyze the main three anti-trafficking policy areas: (i) prosecuting (criminalizing) traffickers, (ii) protecting victims, and (iii) preventing the crime of human trafficking. Each sub-index of prosecution, protection and prevention is aggregated to the overall index with an unweighted sum, with the overall index ranging from a score of 3 (worst) to 15 (best). It is available for up to 177 countries over the 2000-2009 period (on an annual basis).

The outcome of the Index shows that anti-trafficking policy has overall improved over the 2000-2009 period. Improvement is most prevalent in the prosecution and prevention areas worldwide. An exception is protection policy,[56] which shows a modest deterioration in recent years.

In 2009 (the most recent year of the evaluation), seven countries demonstrate the highest possible performance in policies for all three dimensions (overall score 15). These countries are Germany, Australia, the Netherlands, Italy, Belgium, Sweden and the US. The second best performing group (overall score 14) consists of France, Norway, South Korea, Croatia, Canada, Austria, Slovenia and Nigeria. The worst performing country in 2009 was North Korea, receiving the lowest score in all dimensions (overall score 3), followed by Somalia. For more information view the Human Trafficking Research and Measurement website.
In 2014, for the first time in history major leaders of many religions, Buddhist, Anglican, Catholic, and Orthodox Christian, Hindu, Jewish, and Muslim, met to sign a shared commitment against modern-day slavery; the declaration they signed calls for the elimination of slavery and human trafficking by the year 2020.[58] The signatories were: Pope Francis, Mātā Amṛtānandamayī (also known as Amma), Bhikkhuni Thich Nu Chân Không (representing Zen Master Thích Nhất Hạnh), Datuk K Sri Dhammaratana, Chief High Priest of Malaysia, Rabbi Abraham Skorka, Rabbi David Rosen, Abbas Abdalla Abbas Soliman, Undersecretary of State of Al Azhar Alsharif (representing Mohamed Ahmed El-Tayeb, Grand Imam of Al-Azhar), Grand Ayatollah Mohammad Taqi al-Modarresi, Sheikh Naziyah Razzaq Jaafar, Special advisor of Grand Ayatollah (representing Grand Ayatollah Sheikh Basheer Hussain al Najafi), Sheikh Omar Abboud, Justin Welby, Archbishop of Canterbury, and Metropolitan Emmanuel of France (representing Ecumenical Patriarch Bartholomew.)[58]

Anti-trafficking initiatives Edit
One of the organizations taking the most active part in the anti-trafficking is the United Nations. In early 2016 the Permanent Mission of the Republic of Kazakhstan to the United Nations held an interactive discussion entitled “Responding to Current Challenges in Trafficking in Human Beings”.[59]

One of the current efforts being done to combat human trafficking is an app called TraffickCam[60]. This app was created by the Exchange Initiative[61] and researchers at Washington University. TraffckCam was launched on June 20, 2016 and enables anyone to take photos of their hotel rooms, which then gets uploaded to a large database of hotel images. Since human trafficking victims are often found in hotel rooms for online advertisements, law enforcement and investigators can use these photos to help find and prosecute traffickers.[62]

Anti-trafficking awareness and fundraising campaigns constitute a significant portion of anti-trafficking initiatives.[63] The 24 Hour Race is one such initiative that focuses on increasing awareness among high school students in Asia.[64] The Blue Campaign is another anti-trafficking initiative that works with the U.S. Department of Homeland Security to combat human trafficking and bring freedom to exploited victims.[65]

The Blue Campaign collaborates with law enforcement, government, non-governmental, and private organizations to end human trafficking and protect victims.


Vulnerable Groups Edit
Trafficking in Persons Report released in June of 2016 states that “refugees and migrants; lesbian, gay, bisexual, transgender, and intersex (LGBTI) individuals; religious minorities; people with disabilities; and those who are stateless” are the most at-risk for human trafficking. Governments best protect victims from being exploited when the needs of vulnerable populations are understood.

United Nations Commission on the Status of Women

The Commission on the Status of Women (CSW or UNCSW) is a functional commission of the United Nations Economic and Social Council (ECOSOC), one of the main UN organs within the United Nations. CSW has been described as the UN organ promoting gender equality and the empowerment of women.[1] Every year, representatives of Member States gather at United Nations Headquarters in New York to evaluate progress on gender equality, identify challenges, set global standards and formulate concrete policies to promote gender equality and advancement of women worldwide. In April 2017, ECOSOC elected 13 new members to CSW for a four-year term 2018–2022.[2] One of the new members is Saudi Arabia, which has been criticised for its treatment of women.

UN agencies actively followed their mandates to bring women into development approaches and programs and conferences. Women participate at the prepcoms, design strategy, hold caucus meetings, network about the various agenda items being negotiated in various committees, and work as informed lobbyists at conferences themselves. The CSW is one of the commissions of the UN that do not limit participation to states only. For example, NGOs are also allowed to participate in sessions of the CSW, attending caucuses and panels and organizing their own parallel events through the NGO Committee on the Status of Women, NY (NGO CSW/NY).[3] This is particularly important for contested territories such as Taiwan, which is not a member of the UN. In the past few years, NGOs from Taiwan (such as the National Alliance of Taiwan Women’s Associations) have been able to participate in the CSW sessions.

CSW consists of one representative from each of the 45 Member States elected by ECOSOC on the basis of equitable geographical distribution: 13 members from Africa; 11 from Asia; 9 from Latin America and Caribbean; 8 from Western Europe and other States and 4 from Eastern Europe. Members are elected for four-year terms. Among its activities, the CSW has drafted several conventions and declarations, including the Declaration on the Elimination of Discrimination against Women in 1967 and women-focused agencies such as UNIFEM and INSTRAW. The Commission’s priority theme for its 57th session, March 2013 was the elimination and prevention of all forms of violence against women and girls. Ahead of that an Expert Group Meeting (EGM): prevention of violence against women and girls was held in Bangkok, Thailand, from 17 to 20 September 2012.
The Bureau of CSW plays an important role in the preparation for, and in ensuring that the annual sessions of CSW are successful. Bureau members serve for two years.
The UNCSW was established in 1946 as a mechanism to promote, report on and monitor issues relating to the political, economic, civil, social and educational rights of women. It was a unique official structure for drawing attention to women’s concerns and leadership within the UN. UNCSW first met at Lake Success, New York, in February 1947. All 15 government representatives were women, which distinguished UNCSW from other UN movements, and UNCSW has continued to maintain a majority of women delegates. During its first session, the Commission declared as one of its guiding principles:

to raise the status of women, irrespective of nationality, race, language or religion, to equality with men in all fields of human enterprise, and to eliminate all discrimination against women in the provisions of statutory law, in legal maxims or rules, or in interpretation of customary law.

One of UNCSW’s first tasks was to contribute to the drafting of the Universal Declaration of Human Rights. Commission members inserted gender-sensitive language — arguing against references to “men” as a synonym for humanity and phrases like “men are brothers.” They received resistance from members of the Commission on Human Rights, but succeeded in introducing new, inclusive language.

Reproductive rights and the Commission Edit
Early Work and CEDAW Edit
The Commission began working after its founding in 1946 to directly introduce women’s rights to the international arena.[6] This was achieved through a variety of means, most commonly through attempts to collect data that showed discrimination occurring against women.[6] In conjunction with the emerging global women’s movement, the UN and the CSW named 1976 through 1985 the United Nations Decade for Women. During this time, reproductive rights were included in the central action of the Commission, the Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW) which entered into force in 1981.[6] This convention stipulated that with regards to reproductive rights, reproduction “should not be a basis for discrimination”.[7] It also acknowledges the social implications of motherhood, and states that childcare and maternity protection are integral rights and should be extended to all realms of the lives of women.[7] CEDAW is the only international human rights treaty that overtly references family planning. It states that it is a human right for women “to decide freely and responsibly on the number and spacing of their children and to hove access to the information, education and means to enable them to exercise these rights”, and any state party to the treaty is required to provide education on family planning and reproductive rights, including various forms of contraception.[7][8] Forced abortion or sterilization constitute violations to the treaty.[8] The United States has failed to ratify CEDAW.[9] In addition to CEDAW, the CSW has undertaken several other efforts to address reproductive rights.Throughout this time, the Commission hosted four global conferences on women to address issues including reproductive rights.[10] The locations were Mexico City in 1975, Copenhagen in 1980, and Nairobi in 1985.[10]

Fourth World Conference on Women and Beijing Platform for Action Edit
In 1995, the Commission held the Fourth World Conference for Action, better known as the 1995 Beijing Declaration and Platform for Action.[11] This followed three other conferences addressing the needs and rights of women around the world.[12] The Beijing Platform has been hailed by the Center for Reproductive Rights as “the most comprehensive articulation of international commitments related to women’s human rights.” [13] It places a special emphasis on reproductive rights through its legislation regarding family planning, which states that it is the right of all women “to be informed and to have access to safe, effective, affordable and acceptable methods of family planning of their choice, as well as other methods of their choice for regulation of fertility which are not against the law.”[14] Specifically, the Platform urges state governments to reevaluate punitive measures placed on abortion, provide family planning and a range of contraceptives as alternatives to abortion as well as quality abortion after care.[14] The Platform also presents a safe, healthy pregnancy as a human right which is to be attained through quality resources and healthcare available to all women regardless of economic status.[14] Some scholars have argued that the Platform served to complicate issues of adolescent sexual care and complications resulting from HIV and AIDS.[12]

Reproductive Rights in the Twenty First Century Edit
Since the new millennium, the CSW has also taken action to integrate reproductive rights into the international arena through the creation of the Millennium Development Goals (MDGs), specifically goal 5, which is achieving universal access to reproductive health. In 2005, the UN added a provision to MDG 5 which aimed to “achieve, by 2015, universal access to reproductive health,” determined by the prevalence of contraceptives, adolescent birth rates, the use of prenatal care, and the failure to access family planning methods.[15] The agreements published from the 57th session in 2013 of the CSW also mentions the importance of reproductive rights as human rights and access to safe reproductive care as a means to resolve violence against women. The Declaration also understands this care as a means of prevention of future violence, acknowledges systematic factors and how they influence care and reproductive rights.[16] More recently, the CSW reaffirmed their prioritization of their sexual education, reproductive rights, and reproductive justice for all women including the use of modern family planning options (including a range of contraceptive options) through publishing their 2014 Declaration of Agreements.

What do you understand by animal coloration ????
May 24, 2017

Some animals such as many moths, mantises and grasshoppers, have a repertory of threatening or startling behaviour, such as suddenly displaying conspicuous eyespots or patches of bright and contrasting colours, so as to scare off or momentarily distract a predator. This gives the prey animal an opportunity to escape. The behaviour is deimatic (startling) rather than aposematic as these insects are palatable to predators, so the warning colours are a bluff, not an honest signal.[34][35]

Motion dazzle Edit
Some prey animals such as zebra are marked with high-contrast patterns which possibly help to confuse their predators, such as lions, during a chase. The bold stripes of a herd of running Zebra have been claimed make it difficult for predators to estimate the prey’s speed and direction accurately, or to identify individual animals, giving the prey an improved chance of escape.[36] Since dazzle patterns (such as the Zebra’s stripes) make animals harder to catch when moving, but easier to detect when stationary, there is an evolutionary trade-off between dazzle and camouflage.[36] Another theory is that the zebra’s stripes could provide some protection from flies and biting insects.[37]

Physical protection Edit
Further information: Biological pigment
Many animals have dark pigments such as melanin in their skin, eyes and fur to protect themselves against sunburn[38] (damage to living tissues caused by ultraviolet light).
Some frogs such as Bokermannohyla alvarengai, which basks in sunlight, lighten their skin colour when hot (and darkens when cold), making their skin reflect more heat and so avoid overheating.
Some animals are coloured purely incidentally because their blood contains pigments. For example, amphibians like the olm that live in caves may be largely colourless as colour has no function in that environment, but they show some red because of the haem pigment in their red blood cells, needed to carry oxygen. They also have a little orange coloured riboflavin in their skin.[42] Human albinos and people with fair skin have a similar colour for the same reason.
Animal coloration may be the result of any combination of pigments, chromatophores, structural coloration and bioluminescence.
Pigments are coloured chemicals (such as melanin) in animal tissues.[44] For example, the Arctic fox has a white coat in winter (containing little pigment), and a brown coat in summer (containing more pigment), an example of seasonal camouflage (a polyphenism). Many animals, including mammals, birds, and amphibians, are unable to synthesize most of the pigments that colour their fur or feathers, other than the brown or black melanins that give many mammals their earth tones.[45] For example, the bright yellow of an American goldfinch, the startling orange of a juvenile red-spotted newt, the deep red of a cardinal and the pink of a flamingo are all produced by carotenoid pigments synthesized by plants. In the case of the flamingo, the bird eats pink shrimps, which are themselves unable to synthesize carotenoids. The shrimps derive their body colour from microscopic red algae, which like most plants are able to create their own pigments, including both carotenoids and (green) chlorophyll. Animals that eat green plants do not become green, however, as chlorophyll does not survive digestion.
Chromatophores are special pigment-containing cells that can change their size, thus varying the colour and pattern of the animal. The voluntary control of chromatophores is known as metachrosis.[44] For example, cuttlefish and chameleons can rapidly change their appearance, both for camouflage and for signalling, as Aristotle first noted over 2000 years ago:[46]

The octopus … seeks its prey by so changing its colour as to render it like the colour of the stones adjacent to it; it does so also when alarmed.
When cephalopod molluscs like squid and cuttlefish find themselves against a light background, they contract many of their chromatophores, concentrating the pigment into a smaller area, resulting in a pattern of tiny, dense, but widely spaced dots, appearing light. When they enter a darker environment, they allow their chromatophores to expand, creating a pattern of larger dark spots, and making their bodies appear dark.[47] Amphibians such as frogs have three kinds of star-shaped chromatophore cells in separate layers of their skin. The top layer contains ‘xanthophores’ with orange, red, or yellow pigments; the middle layer contains ‘iridophores’ with a silvery light-reflecting pigment; while the bottom layer contains ‘melanophores’ with dark melanin.
While many animals are unable to synthesize carotenoid pigments to create red and yellow surfaces, the green and blue colours of bird feathers and insect carapaces are usually not produced by pigments at all, but by structural coloration.[45] Structural coloration means the production of colour by microscopically-structured surfaces fine enough to interfere with visible light, sometimes in combination with pigments: for example, peacock tail feathers are pigmented brown, but their structure makes them appear blue, turquoise and green. Structural coloration can produce the most brilliant colours, often iridescent.[44] For example, the blue/green gloss on the plumage of birds such as ducks, and the purple/blue/green/red colours of many beetles and butterflies are created by structural coloration.[48] Animals use several methods to produce structural colour, as described in the table.
Bioluminescence is the production of light, such as by the photophores of marine animals,[49] and the tails of glow-worms and fireflies. Bioluminescence, like other forms of metabolism, releases energy derived from the chemical energy of food. A pigment, luciferin is catalysed by the enzyme luciferase to react with oxygen, releasing light.[50] Comb jellies such as Euplokamis are bioluminescent, creating blue and green light, especially when stressed; when disturbed, they secrete an ink which luminesces in the same colours. Since comb jellies are not very sensitive to light, their bioluminescence is unlikely to be used to signal to other members of the same species (e.g. to attract mates or repel rivals); more likely, the light helps to distract predators or parasites.[51] Some species of squid have light-producing organs (photophores) scattered all over their undersides that create a sparkling glow. This provides counter-illumination camouflage, preventing the animal from appearing as a dark shape when seen from below.[52] Some angler fish of the deep sea, where it is too dark to hunt by sight, contain symbiotic bacteria in the ‘bait’ on their ‘fishing rods’. These emit light to attract prey.

Things you never know about animals !!!
May 24, 2017

The Ecdysozoa are protostomes, named after the common trait of growth by moulting or ecdysis.[97] The largest animal phylum belongs here, the Arthropoda, including insects, spiders, crabs, and their kin. All these organisms have a body divided into repeating segments, typically with paired appendages. Two smaller phyla, the Onychophora and Tardigrada, are close relatives of the arthropods and share these traits. The ecdysozoans also include the Nematoda or roundworms, perhaps the second largest animal phylum. Roundworms are typically microscopic, and occur in nearly every environment where there is water.[98] A number are important parasites.[99] Smaller phyla related to them are the Nematomorpha or horsehair worms, and the Kinorhyncha, Priapulida, and Loricifera. These groups have a reduced coelom, called a pseudocoelom.
The Lophotrochozoa, evolved within Protostomia, include two of the most successful animal phyla, the Mollusca and Annelida.[100][101] The former, which is the second-largest animal phylum by number of described species, includes animals such as snails, clams, and squids, and the latter comprises the segmented worms, such as earthworms and leeches. These two groups have long been considered close relatives because of the common presence of trochophore larvae, but the annelids were considered closer to the arthropods because they are both segmented.[102] Now, this is generally considered convergent evolution, owing to many morphological and genetic differences between the two phyla.[103] Lophotrochozoa also includes the Nemertea or ribbon worms, the Sipuncula, and several phyla that have a ring of ciliated tentacles around the mouth, called a lophophore.[104] These were traditionally grouped together as the lophophorates.[105] but it now appears that the lophophorate group may be paraphyletic,[106] with some closer to the nemerteans and some to the molluscs and annelids.[107][108] They include the Brachiopoda or lamp shells, which are prominent in the fossil record, the Entoprocta, the Phoronida, and possibly the Bryozoa or moss animals.[109]

The Platyzoa include the phylum Platyhelminthes, the flatworms.[110] These were originally considered some of the most primitive Bilateria, but it now appears they developed from more complex ancestors.[111] A number of parasites are included in this group, such as the flukes and tapeworms.[110] Flatworms are acoelomates, lacking a body cavity, as are their closest relatives, the microscopic Gastrotricha.[112] The other platyzoan phyla are mostly microscopic and pseudocoelomate. The most prominent are the Rotifera or rotifers, which are common in aqueous environments. They also include the Acanthocephala or spiny-headed worms, the Gnathostomulida, Micrognathozoa, and possibly the Cycliophora.[113] These groups share the presence of complex jaws, from which they are called the Gnathifera.

A relationship between the Brachiopoda and Nemertea has been suggested by molecular data.[114] A second study has also suggested this relationship.[115] This latter study also suggested that Annelida and Mollusca may be sister clades. Another study has suggested that Annelida and Mollusca are sister clades.[116] This clade has been termed the Neotrochozoa.
Animals can be divided into two broad groups: vertebrates (animals with a backbone) and invertebrates (animals without a backbone). Half of all described vertebrate species are fishes and three-quarters of all described invertebrate species are insects. The following table lists the number of described extant species for each major animal subgroup as estimated for the IUCN Red List of Threatened Species, 2014.3
Over 95% of the described animal species in the world are invertebrates.
Because of the great diversity found in animals, it is more economical for scientists to study a small number of chosen species so that connections can be drawn from their work and conclusions extrapolated about how animals function in general. Because they are easy to keep and breed, the fruit fly Drosophila melanogaster and the nematode Caenorhabditis elegans have long been the most intensively studied metazoan model organisms, and were among the first life-forms to be genetically sequenced. This was facilitated by the severely reduced state of their genomes, but as many genes, introns, and linkages lost, these ecdysozoans can teach us little about the origins of animals in general. The extent of this type of evolution within the superphylum will be revealed by the crustacean, annelid, and molluscan genome projects currently in progress. Analysis of the starlet sea anemone genome has emphasized the importance of sponges, placozoans, and choanoflagellates, also being sequenced, in explaining the arrival of 1500 ancestral genes unique to the Eumetazoa.[118]

An analysis of the homoscleromorph sponge Oscarella carmela also suggests that the last common ancestor of sponges and the eumetazoan animals was more complex than previously assumed.[119]

Other model organisms belonging to the animal kingdom include the house mouse (Mus musculus), laboratory rat (Rattus norvegicus) and zebrafish (Danio rerio).
Animal coloration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. In some species, such as the peacock, the male has strong patterns, conspicuous colours and is iridescent, while the female is far less visible.

There are several separate reasons why animals have evolved colours. Camouflage enables an animal to remain hidden from view. Animals use colour to advertise services such as cleaning to animals of other species; to signal their sexual status to other members of the same species; and in mimicry, taking advantage of the warning coloration of another species. Some animals use flashes of colour to divert attacks by startling predators. Zebras may possibly use motion dazzle, confusing a predator’s attack by moving a bold pattern rapidly. Some animals are coloured for physical protection, with pigments in the skin to protect against sunburn, while some frogs can lighten or darken their skin for temperature regulation. Finally, animals can be coloured incidentally. For example, blood is red because the haem pigment needed to carry oxygen is red. Animals coloured in these ways can have striking natural patterns.

Animals produce colour in different ways. Pigments are particles of coloured material. Chromatophores are cells containing pigment, which can change their size to make their colour more or less visible. Some animals, including many butterflies and birds, have microscopic structures in scales, bristles or feathers which give them brilliant iridescent colours. Other animals including squid and some deep-sea fish can produce light, sometimes of different colours. Animals often use two or more of these mechanisms together to produce the colours and effects they need.
