Standardizing Sustainable Aviation Fuel Definition for Environmental Integrity and Emissions Reduction.

This legislation mandates the Federal Aviation Administration (FAA) to adopt a single, strict definition for "Sustainable Aviation Fuel" (SAF) applicable to all flights within, to, or from the United States. This definition requires these fuels to achieve at least a 50% reduction in lifecycle greenhouse gas emissions compared to standard jet fuel. The goal is to ensure that fuels marketed as sustainable genuinely contribute to reducing aviation's environmental impact and climate change.
