On March 11, 2016, United became the first airline in the world to fly on commercial-scale quantities of such fuels on a continuous basis, which were procured from AltAir Fuels. This fuel was produced from sustainable feedstocks such as non-edible natural oils and agricultural wastes and is expected to provide a greater than 60 percent reduction in carbon dioxide emissions on a lifecycle basis when compared to traditional jet fuel. United has agreed to purchase up to 15 million gallons of sustainable alternative fuel from AltAir Fuels for use in Los Angeles over a three-year period.
