Draft Environmental Assessment

The draft environmental assessment evaluates the potential environmental impacts associated with NHTSA’s proposed action to set Corporate Average Fuel Economy Standards for model year 2008-2011 light trucks. This document describes the environment and resources that might be affected by the proposed light truck CAFE standards for model years 2008-2011, and assesses estimated impacts of alternative actions.

Notice of Proposed Rulemaking
NHTSA: 49 CFR Parts 531, 533, and 537; EPA: 40 CFR Parts 86 and 600 Establish Light-Duty Vehicle Greenhouse Gas Emission Standards and CAFE Standards

EPA and NHTSA are issuing this joint proposal to establish a National Program consisting of new standards for light-duty vehicles that will reduce greenhouse gas emissions and improve fuel economy. 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, and represent a harmonized and consistent National Program. Under the National Program, automobile manufacturers would be able to build a single light-duty national fleet that satisfies all requirements under both programs while ensuring that consumers still have a full range of vehicle choices.
