Interim Joint Technical Assessment Report: Light-Duty Vehicle Greenhouse Gas Emission Standards and Corporate Average Fuel Economy Standards for Model Years 2017-2025

摘要

The Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA, a modal administration within the Department of Transportation) (the agencies) are collaborating with the California Air Resources Board (CARB) to build on the success of the first phase of the National Program to regulate fuel economy and greenhouse gas (GHG) emissions from U.S. light-duty vehicles. The strong and coordinated first phase of standards for model years (MY) 2012-2016 was completed in April 2010, ensuring that all manufacturers can build a single fleet of U.S. vehicles to meet the new harmonized standards.
