Alternative Jet Fuels and Deployment

A first article entitled "Aviation fuels" [TRP 4 054] already explained what jet fuel obtained from fossil resources is, its properties, specifications and means of production, and the ASTM D4054 certification procedure for alternative fuels. , as well as the alternatives envisaged for future aircraft propulsion and, finally, the list of certified synthetic fuels. .

To contribute to efforts to limit the rise in global temperature, despite the significant growth forecast for air transport (+4-5%/year before the pandemic, and probably more like +3-4%/year after it from 2023/2024 onwards), the players in this mode of transport had already set themselves three ambitious objectives some ten years ago:

• + 1.5%/year improvement in energy efficiency ;

• stabilization of the sector's net CO ₂ emissions in 2020 ;

• - 50% lower CO ₂ emissions in 2050 than in 2005.

These objectives will be achieved by acting on four pillars: aircraft and fuel technology, infrastructure, air traffic operations and Global Market-Based Measure (GBM). ) via an aviation-specific CO ₂ market, CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation). .

Today, these objectives are even more voluntary. For example, on November 10, 2021, the International Air Transport Association, IATA, which represents over 300 airlines worldwide, proposed a strategy to go even further. The aim is to achieve carbon neutrality by 2050 through...
