The climate impact of air transport is quite important, but difficult to evaluate precisely. In fact, in addition to carbon dioxide (CO2), a relatively easy-to-account greenhouse gas with emissions accounting for 2-3% of global emissions , aircraft are responsible for other emissions whose contribution to the greenhouse effect is not…

The environmental impact of aviation occurs because aircraft engines emit heat, noise, particulates, and gases which contribute to climate change and global dimming. 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…
