The jet fuel that’s used by major airlines isn’t just a pollutant; it’s also the companies’ biggest expense. To cut back on carbon emissions and budget, these five airlines are turning to sustainable biogas.

United Airlines: Following a $30 million investment – the largest of its kind so far by a domestic airline – United is now using biogas that’s made from farm waste and animal fat oil. Currently, planes fly with a mix of 30 percent biofuel and 70 percent traditional jet fuel but United’s plans include blending biogas into its overall supply.

Alaska Airlines: In 2011 Alaska Airlines became the first United States commercial airline to run its regularly scheduled flights using biogas derived from cooking oil. It flew 75 flights between Seattle and Washington D.C., and Seattle and Portland, with that original stock. Now, the company is setting goals to use sustainable biogas in one or more of its airports by 2020.

Southwest Airlines: The budget carrier is purchasing low carbon renewable jet fuel rendered from forest residues and its first delivery is expected next year. By collecting and using forest clippings, the company helps cut down on the risk of wildfires in the Western states. Southwest’s agreement with its biogas provider includes 3 million gallons per year.

British Airways: Not only is British Airways committing to a purchase of $550 million worth of biogas, it’s also providing funds and capital for the development of a facility that will turn landfill waste into renewable jet fuel. Approximately 633,800 tons of post-recycled waste will be converted to 132,270 tons of clean burning liquid fuel.

FedEx: It’s not a commercial airliner, but the delivery service is making big strides in the implementation of renewable biogas. FedEx Express will purchase and use about 3 million gallons of low-carbon renewable jet fuel per year from 2017 to 2024. The biogas will be made from the same forest wood waste as Southwest Airlines’.
