The U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) issued final rules extending the National Program to further reduce greenhouse gas (GHG) emissions and improve fuel economy for model years (MYs) 2017 through 2025 light-duty vehicles. EPA is established national GHG emissions standards under the Clean Air Act, and NHTSA is established Corporate Average Fuel Economy (CAFE) standards under the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act (EISA).
