Air travel accounts for 4% of greenhouse gas (GHG) emissions from the transport sector and 1.2% of French emissions. For short-haul flights, the French Agency for Ecological Transition (ADEME) estimates that GHG emissions per passenger-km represent 0.2 kg of CO2, making air travel a highly polluting mode of transport.
In 2022, ADEME published three ecological transition scenarios for the sector, which mobilise three decarbonisation levers at different scales: improving the energy efficiency of aircraft, using sustainable fuels to reduce the carbon intensity of energy, and controlling and reducing traffic.
