Cars and Light Trucks
Light Duty Greenhouse Gas Standards Compliance Information
The U.S. Environmental Protection Agency and the National Highway Transportation Safety Administration issued national light-duty greenhouse gas and fuel economy standards on April 1, 2010. The greenhouse gas standards apply to cars and light trucks, beginning with the 2012 model year. Manufacturers must meet standards for tailpipe methane and nitrous oxide emissions, plus increasingly stringent fleet average standards for carbon dioxide in each model year through 2016. The regulations provide flexibility to meet the standards by enabling manufacturers to generate emission credits which they may save for future years or sell to other manufacturers.
