Sustainable Aviation Fuel (SAF)
Jet fuel made from non-fossil sources, such as waste oils or synthetic processes, that can reduce lifecycle emissions compared with conventional kerosene.
EcoAppraise context
Airline claims about SAF should state the share actually used and the lifecycle reduction, not imply that flights are low carbon.
