A bipartisan group of US Senators has introduced legislation that would update federal standards for the definition of sustainable aviation fuel at the Federal Aviation Administration and require agencies to adopt the GREET model, which the Senators say is the most accurate tool for measuring lifecycle emissions.
The Duckworth-Fischer-Ernst-Klobuchar Sustainable Aviation Fuels Accuracy Act of 2023 would identify the standards required to meet the definition of SAF at the FAA by:
• Requiring the Federal Government adopt the most up-to-date lifecycle emissions models,including, GREET or successor LCA models to GREET;
• Preventing the Federal Government from picking winners and losers in the SAF market; and
• Clarifying that the United States Government does not encourage the banning of agriculturalfeedstocks from being utilized as a viable source of SAF.
