Timothy cox fort worth texas polution of the aviation

Career Summary:

According to the aviation industry, 2% of global C02 emissions are emitted by aircraft. Timothy cox fort worth Texas - Free stock market game When, for example, made ​​a round trip Paris / New York by plane, first class, over 2.5 tons of CO2 are emitted. Aerodromes distribute more than 27% of fuel products in the world.

Aviation. A palpable pollution

The plane emits between 134 and 148 grams of CO2 per voyageur.kilomètre (against 2.6 grams for the train) and any additional kilometer flight meant extra kerosene burned in the atmosphere. But for every pound of kerosene used, it is 3 pounds of C02 are emitted.

Pollution avionsGlobalement, of serious and compelling epidemiological studies are lacking. However, many oncologists as Dominique Belpomme about Roissy, an alarm is initiated. It explains a CGT site "environmentally, Roissy is a very bad neighbor".

A study by Inserm found that children living within 200 m of a service station have a risk quadrupled to declare leukemia. There is no doubt that the airport areas are damaged. Timothy cox fort worth texas conference about maintaining the water quality The atmosphere, but also the cultures. When it rains, atmospheric dust settles.

According to the Nicolas Hulot Foundation, aviation is, of all modes of transport, as issuer of greenhouse gas emissions. Per passenger per kilometer traveled, mode of transport is three times more harmful to the climate than the car. A return trip from London to New York produces about as much gas emissions greenhouse someone to warm up for one year.

Since 1990, emissions from this sector in the EU increased by 110%, if compared to the cost of increasingly low this mode of transport.

Nitrogen oxides

Emissions of NOx (nitrogen oxides) are the most common especially during takeoff and climb.

Approximately three quarters of emissions occur during the flight to the cruise speed in the troposphere and lower stratosphere (10-12 km).

     Aviation contributes to climate change in several ways

  •      - With CO2 emissions;
  •      - For those of nitrogen oxide (NOx), which have indirect effects on the climate because they produce ozone, which is a greenhouse gas emissions;
  •      - The steam produced by planes and leading to the formation of condensation trails, which tend to warm the surface of the earth.

     Timothy cox fort worth texas combating deforestation Currently, the contribution of aviation to global emissions of greenhouse gas emissions in the EU is estimated at 3%. But this impact is 2 to 4 times greater if one takes into account all the above parameters (IPCC Special Report 1999). If nothing is done, the emissions from this sector should double or even triple by 2050, wiping out any chance of limiting global warming well below 2 ° C by the end of this century.

Planes emit carbon dioxide (CO2) and water vapor. Aircraft engines emit pollutants mainly the following components:

  •      nitrogen oxides (NOx),
  •      carbon monoxide (CO),
  •      hydrocarbons (HC) (or volatile organic compounds: VOC)
  •      sulfur dioxide (SO2)
  •      and solid particles (SOOT).

 Timothy Cox Fort Worth Texas Protecting resources of our natural environment At idle, and thus the ground, the engine releases NOx but also a lot of CO and HC. Takeoff and climb NOx and particulate matter (soot) are strong while those of CO and HC are they more limited.

The spread of toxic gas has a much stronger impact in the immediate vicinity of the tracks, especially under certain atmospheric conditions (such as when the temperature inversion or fog). This pollution, which exceeds the limits recommended by WHO, has become an environmental and public health problem recognized by all health authorities.

     According associations, 2,300 planes taking off from Orly, Roissy and Le Bourget produce the same amount of NOx that 2.3 million cars each traveling 25 km Diesel. Suffice to say that the concerns are growing about the impact of these emissions on human health.

Aviation - a global impact actually quite limited but growing fast


Pollution is officially attributed to air transport does not exceed 4% of the world transport pollution. The concern comes right from the growth in air traffic.

What can not be disputed is that aviation is one of the most growing sectors for years in terms of carbon dioxide. A doubling of the number of passengers is expected in 2008 and 2018 and to double or triple by 2025.

aircraft pollution

The year 2004 was a record year with 14% growth in air traffic. Airbus expects the number of commercial aircraft in operation will double by 2025 and increase from 12,676 end 2005 to 27 307, the FAA, the American air traffic control authority, predicted that due to the growth in traffic emissions greenhouse gas emissions will increase in the United States by 60% over the same period.

Most aviation manufacturers and airlines are trying to prepare for an obligation low C02 emissions and therefore lower fuel consumption.

     Namely Aviation

         The European Parliament adopted a text requiring aircraft flying over Europe to reduce their C02 emissions by 10% by 2011 or they will have to buy carbon credits on the European market for carbon emissions trading EU ETS.

         Richard Branson, the British CEO promised to reinvest the profits of its trains and its planes over 10 years - $ 3 billion - in the fight against global warming.

         Zurich Airport has adopted the principle of "environmental bubble", which amounts to considering an airport as a source of industrial pollution, such as an incineration plant for example. We then calculate the emissions of the site (the airport) and imposes thresholds for selected by the WHO and European Directives.

Aviation - Milestones and polution

     Carbon monoxide (CO) is a poisonous to hemoglobin.
     Nitrogen oxides NOx and SO2 sulfur gases very irritating to the respiratory tract.
     Nitrogen oxides NOx are transformed under the influence of ultra-violet rays in Ozone O3.
     Ozone is a gas that is found in both the upper atmosphere - where it shields the Earth from the sun's UV - a gas in which each molecule is composed of three oxygen atoms (O3). It is a greenhouse gas, which occurs naturally in the atmosphere, where its concentration is increased by human activities. Ozone irritates the lungs.
