The Ninth Circuit Court of Appeals ruled that the National Highway Traffic Safety Administration (NHTSA) violated the Energy Policy and Conservation Act by exempting SUVs and pickup trucks from fuel-economy standards. The Energy Policy and Conservation Act requires that the NHTSA set corporate average fuel-economy (CAFE) standards at the maximum feasible level. The court’s decision in the case requires that the NHTSA undertake a full environmental review of the gas-mileage standards.
