Greenhouse Gas Emissions
In the context of aviation, Greenhouse Gas Emissions refer to the gases released into the atmosphere as a result of aircraft operations. These emissions are a significant contributor to global warming and climate change. The primary greenhouse gases emitted by aircraft are carbon dioxide (CO2) and water vapor (H2O), but aircraft also emit other gases such as methane (CH4) and nitrous oxide (N2O), which have a much higher warming potential than CO2. The emissions are produced by the combustion of aviation fuel in the aircraft's engines during flight, and to a lesser extent during taxiing, takeoff, and landing. The level of emissions varies depending on the type of aircraft, the type of engine, the altitude at which the aircraft is flying, and the length of the flight. Shorter flights tend to produce more emissions per passenger mile than longer flights because a significant proportion of emissions are produced during takeoff and landing. The aviation industry is actively seeking ways to reduce its greenhouse gas emissions, including through the development of more fuel-efficient aircraft and engines, the use of sustainable aviation fuels, and operational measures such as optimizing flight paths.
