Sustainable Aviation Fuels Accuracy Act of 2023

This bill establishes a clear, uniform definition for sustainable aviation fuel (SAF) that must be used by the Federal Aviation Administration (FAA) for all aircraft operating in the U.S. and all FAA programs. It requires SAF to meet specific technical standards (like ASTM D7566), not be made from palm oil or petroleum, and achieve at least a 50% reduction in lifecycle greenhouse gas emissions compared to conventional jet fuel. The definition applies directly to airlines, fuel producers, and the FAA in managing aviation fuel programs and regulations. The rule ensures consistent measurement of SAF's environmental benefits across the industry.
