White streaks are sometimes observed in the wake of aircraft. In some cases, these can turn into cirrus clouds which, depending on their persistence in the atmosphere, can alter the planet’s radiation balance and possibly contribute to global warming.
While certain local humidity and temperature conditions are required for the formation of these trails, the propulsion system and fuel directly impact their characteristics and their ability to evolve into cirrus clouds.

Opinion N°20: Decarbonising air transport
Air transport is global: it has enabled an incredible expansion in relations between peoples. It intends to be sustainable in the face of the climate challenge and is aiming for carbon neutrality by 2050.
Decarbonising aviation involves 4 levers: (a) a sharp reduction in aircraft fuel consumption; (b) the use of alternative fuels to kerosene; (c) carbon capture and storage to “neutralise” emissions from the remaining fossil kerosene; (d) sobriety… Read More
