The San Francisco 49ers have made history as the first NFL team to purchase sustainable aviation fuel (SAF) in partnership with United Airlines, aiming to reduce game-related flight emissions. This initiative aligns with United's commitment to achieve net-zero greenhouse gas emissions by 2050 and follows their purchase of more SAF than any other U.S. airline in 2023. SAF can cut greenhouse gas emissions by up to 85% over its lifecycle, and United's supply is certified for sustainability. The 49ers plan to use SAF for their upcoming flight to Los Angeles, marking a significant step in their ongoing sustainability efforts. Both organizations are focused on raising awareness about the potential of sustainable fuels in reducing aviation emissions. Through this collaboration, the 49ers reinforce their dedication to environmental stewardship, including prior achievements like LEED Gold certification for Levi's Stadium.
