Impacts of Airplane Pollution on Climate Change and Health:
Despite their shiny chrome exterior, an airplane,
just like a power plant or an oil refinery, is dirty. Worse still, it is an
industry on the move, growing in size and pollution in leaps and bounds. The
governments of the world have the opportunity to dramatically cut airplane
pollution, and help the climate. But until United Airlines and other airlines
clean up their operations and support common sense, low-cost emissions
reduction policies, aviation pollution will just keep growing, hurting local
communities and the global climate.
Airplanes achieve such extraordinary
levels of energy consumption and carbon emissions by burning large quantities
of toxic jet fuel. This fuel produces, in addition to carbon dioxide, NOx,
sulphates, and particulate matter, all of which amplify the impact of aviation
on global warming. Airplanes emit all of these pollutants directly into the
atmosphere, compounding the pollutants’ warming impact. Even those innocuous-looking
contrails trap heat on the Earth’s surface. The combined effect of all of these
pollutants multiplies the global warming impact of aviation, making aviation
currently responsible for an estimated 5% of global climate pollution.
The burning of incredible quantities of
toxic fuel has impacts that extend beyond the climate. As soon as airplanes
leave the gate, they begin to produce phenomenal amounts of nitrogen oxides
(NOx), carbon monoxide, particulate matter, and cancer-causing toxics such as benzene
and formaldehyde. 3 This pollution travels miles downwind,
contributing to asthma, lung and heart disease, and a large number of cancers.
