Title: ●Passenger Car and Light Truck Corporate Average Fuel Economy Standards MYs 2012-2016 
Abstract: This joint NHTSA/EPA rulemaking would establish a National Program consisting of new standards for light-duty vehicles that will reduce greenhouse gas emissions and improve fuel economy. This rulemaking would be consistent with the National Fuel Efficiency Policy announced by President Obama on May 19, 2009, responding to the country’s critical need to address global climate change and to reduce oil consumption. EPA is proposing greenhouse gas emissions standards under the Clean Air Act, and NHTSA is proposing Corporate Average Fuel Economy standards under the Energy Policy and Conservation Act, as amended. These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016. They require these vehicles to meet an estimated combined average emissions level of 250 grams of CO2 per mile in MY 2016 under EPA’s GHG program, and 34.1 mpg in MY 2016 under NHTSA’s CAFE program and represent a harmonized and consistent national program (National Program). Under the National Program, the overall light-duty vehicle fleet would reach 35.5 mpg in MY 2016, if all reductions were made through fuel economy improvements. The Program would result in approximately 950 million metric tons of CO2 emission reductions and approximately 1.8 billion barrels of oil savings over the lifetime of vehicles sold in model years 2012 through 2016. This rulemaking action was inadvertently published under RIN 2127-AK90.

Action Source Description Date
Final  Statutory  Final rule for Model Year 2012  04/01/2010 

Statement of Need: NHTSA is required by statute to establish the CAFE standard for a model year not later than 18 months before its beginning, and thus must publish the final rule for model year 2012 on or before April 1, 2010.

Summary of the Legal Basis: Section 32910(d) of Title 49 of the United States Code provides that the Administrator may prescribe regulations necessary to carry out his duties under Chapter 329, Automobile fuel economy.

Alternatives: The agency is not pursuing any alternatives.

Anticipated Costs and Benefits: The costs and benefits of the potential changes addressed in this action have not yet been assessed.

Risks: Depending on how manufacturers address Federal fuel economy requirements, there is some potential effect on safety. The most recent NHTSA analysis (2003) indicated that the association between vehicle weight and overall crash fatality rates in heavier MY 1991-99 light trucks and vans was not significant. However, for three other groups of MY 1991-99 vehicles - the lighter LTVs (light trucks and vans), the heavier cars, and especially the lighter cars - fatality rates increased as weights decreased.
