Jefferies: Some Sustainable Aviation Fuels Are Greener Than Others
Report shows the amount of lifecycle CO2 emissions savings can vary greatly

A recent report from investment analyst Jefferies shows that not all sustainable aviation fuels (SAF) are the same in terms of its environmental benefits, which can vary significantly depending on which of 11 approved pathways is used to produce them.

Jefferies based its findings on a discussion it hosted with International Air Transport Association (IATA) SAF specialist Daniel Bloch on policy approaches for increasing SAF production and availability. With a wide variety of feedstocks available, some production pathways—and the feedstocks they use—offer significantly better CO2 reduction in their lifecycles, Bloch noted.
