Impact Of Air Transport On Environment
Impact of Air transport on environment can not be ruled out for the aircraft engines emit noise, and the gases emitted contribute to climate change and global dimming. The fast growth of air transport in recent years has contributed to an increase in total pollution. Let us study the environmental impact of Air transport in this article.
Between 1990 and 2006, the greenhouse gas emissions from Air transport have been known to increase by 87%. There has been an ongoing discussion about possible taxation of air travel plus the enclosure of aviation in an emissions trading scheme. This is to ensure that the total peripheral costs of aviation are taken into account. Read on to know more on Air transport and environment.
Like any other activity involving combustion, using powered aircraft whether they are hot air balloons or airliners, soot and other pollutants are released the atmosphere. This also produces the greenhouse gases such as carbon dioxide. Moving on with the discussion on environment and Air transport, in addition to the CO2 released by most aircraft in flight through the burning of fuels, the air transport industry also adds to the greenhouse gas emissions from airport vehicles on the ground used by passengers and staff to access airports. Plus one cannot ignore the emissions produced by the energy used in airport buildings or the manufacturing of aircraft and also the construction of airport infrastructure.
In addition, there are some specific impacts of Air transport on environment:
• The water vapor contrails released by high-altitude jet airliners also contribute to the formation of cirrus cloud.
• Aircraft, mainly large jet airliners which fly at high altitudes near the tropopause release aerosols and leave contrails. Both of which can augment cirrus cloud formation.
• Aircraft flying at high altitudes near the tropopause can also produce chemicals which then intermingle with greenhouse gases at those altitudes, like the nitrogen compounds, which then interact with ozone, and thus increase the ozone concentrations.
• Most light piston aircraft burn avgas, consisting of tetra-ethyl lead (TEL), a highly-toxic substance which can cause soil pollution at airports. As an improvement, some lower-compression piston engines operating on unleaded mogas, and turbine engines and diesel engines, none of which requires lead are appearing on some newer light aircraft.
We hope you found the above article on the impact of Air transport on environment both informative and useful.
