| 摘要： | The Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) are issuing a joint final rule to establish new standards for light-duty highway vehicles that will reduce greenhouse gas emissions and improve fuel economy. This joint final rulemaking is consistent with the Presidential Memorandum issued by President Obama on May 21, 2010, requesting that NHTSA and EPA develop through notice and comment rulemaking a coordinated National Program to reduce greenhouse gas emissions and improve the fuel economy of light-duty vehicles for model years 2017-2025. This final rule, consistent with the Presidents request, responds to the countrys critical need to address global climate change and to reduce oil consumption. EPA is regulating greenhouse gas emissions standards under the Clean Air Act, and NHTSA is regulating 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 2017 through 2025. They require these vehicles to meet an estimated combined average emissions level of 163 grams of CO2 per mile in MY 2025 under EPAs GHG program, and 49.6 mpg in MY 2025 under NHTSAs CAFE program and represent a harmonized and consistent national program (National Program). These standards are designed such that compliance can be achieved with a single national vehicle fleet whose emissions and fuel economy performance improves each year from MY2017 to 2025. This document describes the supporting technical analysis for areas of these joint rules which are consistent between the two agencies. NHTSA and EPA have coordinated closely to create a nationwide joint fuel economy and GHG program based on consistent compliance structures and technical assumptions. To the extent permitted under each Agencys statutes, NHTSA and EPA have incorporated the same compliance flexibilities, such as averagin |
