The Sustainable Aviation Fuels (SAF) Observatory ranks 77 airlines and airline groups worldwide on their use of and commitment to SAF. It also tracks where SAF is being produced, which airports and airlines are using it and much more.
Airlines and airline groups were scored from 0 to 100 based on their expected emissions reductions through SAF and their shares of advanced and waste biofuels and e-kerosene. No airline ranks in category A and the majority rank in category D, highlighting how much progress airlines still need to make.
Not all SAFs are equally sustainable. E-kerosene, a fuel that is made from renewable electricity, is the only type of SAF that can be sustainably scaled up to meet the growing energy demand of the aviation sector. In contrast, SAF derived from biomass (biofuels) vary greatly in sustainability and scalability. Biofuels made from genuine waste residues can be sustainable but are in limited quantities, while advanced biofuels might have competing uses in other sectors and those made from food or feed crops (e.g. corn) are by far the least sustainable ones.
