Boeing, Netflix and Microsoft among founders of new business alliance on sustainable aviation fuels A new alliance to help scale sustainable aviation fuels (SAF) by increasing and unifying corporate demand has been backed by a string of big-name businesses, including Boeing, Deloitte, Microsoft and JP Morgan Chase. The first flight using blended biofuel took place in 2008. But, in 2019, less than 6% of all aviation fuel used globally was classed as sustainable. Launched on Tuesday (20 April), the Sustainable Aviation Buyers Alliance (SABA) is being operated by the Environmental Defence Fund and Rocky Mountain Institute, with support for the Climate Group, best known for schemes such as RE100 and EV100.
