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.
Key points
Establishes a mandatory, nationwide definition of Sustainable Aviation Fuel (SAF) for all US aviation activities, increasing environmental accountability.
SAF must demonstrate a minimum 50% reduction in lifecycle greenhouse gas emissions, measured by recognized international or US models.
The definition explicitly excludes fuels derived from petroleum or palm fatty acid distillates, promoting cleaner, non-controversial sources.
