Greenhouse Gas Emission Standards for Light-Duty Vehicles: Manufacturer Performance Report for the 2012 Model Year

On May 7, 2010, the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) issued a joint Final Rule to establish a National Program with new standards for light-duty vehicles that reduce greenhouse gas emissions and improve fuel economy. EPA finalized greenhouse gas emissions (GHG) standards under its authority in the Clean Air Act, and NHTSA finalized Corporate Average Fuel Economy (CAFE) standards under the Energy Policy and Conservation Act of 1975, as amended (EPCA). These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016, and represent the first phase of the EPA and NHTSA joint harmonized National Program. On October 15, 2012, EPA and NHTSA issued a subsequent rulemaking further reducing greenhouse gas emissions and improving the fuel economy of light-duty vehicles for model years 2017–2025, building on the success of the first phase of the joint National Program. In March 2013, EPA released a report documenting manufacturers’ use of the early credit provisions allowed under the GHG standards for the 2009-2011 model years. EPA is releasing this subsequent report as part of our continuing commitment to provide the public with transparent and timely information about manufacturers’ compliance with the GHG program. This report summarizes the information presented in the March 2013 report and presents substantial detail regarding the performance of the manufacturers towards meeting GHG standards in the 2012 model year – the first model year of the standards.
