The Flex Fuel Fairness Act of 2023 directs the EPA to allow manufacturers to claim lower carbon dioxide emissions for vehicles that run on E85 fuel, a blend of 85 percent ethanol and 15 percent gasoline. Under the bill, manufacturers could count flex fuel vehicles as producing 31 percent lower emissions than comparable gasoline-only vehicles when calculating their fleet-wide average emissions to meet federal standards, based on research showing E85 reduces greenhouse gases by that amount. The EPA must implement this change within 120 days of the bill becoming law and may increase the emissions reduction percentage if newer scientific models show an even greater benefit from E85 fuel. The bill affects automakers trying to comply with federal fuel economy and emissions regulations, potentially making it easier for them to meet environmental standards without producing as many zero-emission vehicles. No specific funding is authorized in the legislation.
