Flex Fuel Fairness Act of 2023

The Flex Fuel Fairness Act of 2023 requires the Environmental Protection Agency (EPA) to adjust emissions calculations for flexible fuel vehicles (FFVs) that run on E85 (a fuel blend containing 85% ethanol). It mandates that the EPA use a 31% lower CO2 emissions value for FFVs compared to standard gasoline vehicles, based on a study showing E85 reduces emissions by 31% per mile. This change directly helps vehicle manufacturers meet federal fleet emissions standards by making it easier to count FFVs as lower-emission vehicles. The EPA may further adjust this percentage higher if future studies support a larger reduction.
