Flex Fuel Fairness Act of 2023

The Flex Fuel Fairness Act of 2023 requires the Environmental Protection Agency (EPA) to adjust emission calculations for flexible fuel vehicles (FFVs) that run on E85 ethanol fuel. Specifically, within 120 days of enactment, the EPA must revise regulations to allow manufacturers to use a 31% lower CO2 emission value for FFVs compared to standard gasoline vehicles, based on the Argonne National Laboratory's GREET model findings. This change directly affects vehicle manufacturers by providing a reduced emissions credit for FFVs when meeting federal fleet average CO2 standards. The bill also permits future adjustments to this percentage if updated GREET model data supports a larger reduction. The policy change aims to align regulatory calculations with the demonstrated emissions benefits of E85 fuel.
