All three companies are affiliate members of the Sustainable Aviation Fuel Users Group (www.safug.org), which includes 23 leading airlines responsible for approximately 25 percent of annual aviation fuel use.

The Sustainable Aviation Fuel Users Group was formed in September 2008 with support and advice from the world's leading environmental organizations such as the Natural Resources Defense Council and the Roundtable for Sustainable Biofuels (RSB). The group is focused on accelerating the development and commercialization of sustainable aviation biofuels.

All members have signed a Sustainability Pledge, and believe that a key driver to a carbon neutral industry is advancing and adopting sustainable aviation biofuels. Sustainable aviation biofuels will perform equal to, or better than, petroleum based fuels and will have a carbon neutral lifecycle - production through use.
