Biden Administration Finalizes Less Stringent Auto-Emissions and Fuel Economy Rules for Hybrid Trucks, SUVs, 38 mpg by 2031

The Biden administration has finalized new U.S. auto-emissions regulations and fuel economy rules that are less stringent than originally proposed. Announced in March and finalized in June, the new regulations allow for a slower transition to electric vehicles, responding to industry pushback. The finalized rules, which apply through 2031, require new vehicles to achieve a real-world mileage standard of 38 miles per gallon by 2031. The plan includes flexibility for increased use of electric vehicles, a key priority for President Biden. Despite the concessions, the administration asserts that the rules will reduce gas consumption and save on fuel costs. The new rules also address hybrid trucks and SUVs, with the National Highway Traffic Safety Administration (NHTSA) involved in the process. Additionally, automakers are required to achieve an average of 65 miles per gallon across all models by 2031, with fuel economy increasing 2% per year for model years 2027-2031 for passenger cars.
