Scottsdale—Nov. 2, 2023—USA BioEnergy, LLC (“USA BioEnergy”) today announced a 20-year offtake agreement with Southwest Airlines Co. (“Southwest”) under which Southwest may purchase up to 680 million gallons of neat sustainable aviation fuel (“SAF”). Once blended with conventional jet fuel, the SAF could produce the equivalent of 2.59 billion gallons of net-zero1 fuel and avoid 30 million metric tons of CO2 over the agreement term. Southwest® plans to begin purchasing SAF from USA BioEnergy’s facility near Bon Wier, Texas, as early as 2028. Additionally, as part of the offtake agreement, USA BioEnergy and Southwest have established a long-term strategic relationship offering Southwest the opportunity to purchase up to another projected 180 million gallons of SAF per year from future planned production facilities.
1. Net zero is determined by a fuel with a carbon intensity of zero (0) gCO2e/MJ or lower on a lifecycle basis.

“Southwest is focused on achieving our goal to replace 10 percent of our total jet fuel consumption with SAF by 2030,” said Michael AuBuchon, Managing Director of Fuel Strategy and Management at Southwest Airlines. “This offtake agreement with USA BioEnergy marks important progress in the development of our SAF portfolio, furthering our environmental sustainability goals with the opportunity to grow our strategic relationship and potentially purchase more SAF in the future.”

“Our agreement with Southwest Airlines is a perfect fit because it aligns Southwest’s goal of reaching net zero carbon emissions by 2050 and USA BioEnergy’s goal of becoming the leading producer of carbon-negative fuel. USA BioEnergy is excited to work with Southwest on this initial project and, potentially, future sites we may add in our pipeline,” said David Prom, Chairman of the Board, Co-Founder of USA BioEnergy.

“USA BioEnergy has been working with Michael AuBuchon and his team to create this strategic SAF offtake agreement. Southwest has an industry-leading balance sheet and investment-grade credit ratings from all three leading credit rating agencies. We could not be prouder of Southwest Airlines and the entire team who worked to make this happen,” said Nick Andrews, CEO, Co-Founder of USA BioEnergy. “With our plan to produce significant quantities of SAF, USA BioEnergy looks forward to the opportunity to help Southwest get closer to its goal of net zero carbon emissions by 2050. We plan to work with Southwest for decades as we add new biorefinery locations and scale our SAF volumes. This offtake agreement is a monumental step for USA BioEnergy in our goal of becoming the world’s leader in advanced biofuels.”
