Boeing Corporation started the [[Sustainable Aviation Fuel Users Group in the fall of 2008 . Boeing says the Sustainable Aviation Fuel Users Group includes airlines that are serious about a commitment to improving their performance in carbon reduction and other sustainability measures and must take a pledge before being considered for the group. Alaska Airlines was among the five carriers accepted July 13, making it the first U.S.-based carrier in the group.

The group includes Air France?, Air New Zealand?, All Nippon Airways?, Cargolux?, Gulf Air?, Japan Airlines?, KLM?, SAS?, and Virgin Atlantic Airways?. Joining in July 2009 were Alaska Airlines?, British Airways?, Cathay Pacific?, TUIfly? and Virgin Blue?.

To join, an airline has to do more than acknowledge that developing sustainable jet fuel is the right way to go. It has to agree to consider only renewable fuel sources that minimize biodiversity impacts: fuels that require minimal land, water and energy to produce, and that don?t compete with food or fresh water resources. In addition, cultivation and harvest of plant stocks must provide socioeconomic value to the local communities.

For an airlines to get in they have to be accepted by the members¹. Boeing and Honeywell International's UOP LLC are associate members.
