3、ORDThe aeronautics industry is facing increasing pressure to reduce its carbon footprint and mitigate its impact on the environment.Sustainable aviation fuels(SAFs)represent one major potential solution to this challenge,as they are seen as the main lever for decarbonization in the medium term due t
