Gas Turbine Pollutant Emissions (IMechE Seminar Publications)

Emissions from civil subsonic air traffic are potentially in sufficient amounts to affect climate, particularly with the projected growth in air traffic. The main concern, which in the past was centred on air quality in the vicinity of airports, is now focused on the net global warming effects of emissions of oxides of nitrogen, carbon dioxide and contrails generated at altitude. The scientific debate is ongoing and engine manufacturers are studying a range of new low-emission and fuel-efficient technologies aimed at addressing all environmental concerns in a balanced manner.
