Sustainable aviation fuel

Sustainable aviation fuel (SAF) is the name given to advanced aviation biofuel types used in jet aircraft and certified as being sustainable by a reputable independent third-party, such as the Roundtable on Sustainable Biomaterials (RSB). This certification is in addition to the safety and performance certification, issued by global standards body ASTM International, that all jet fuel is required to meet in order to be approved for use in regular passenger flights.
