U.S. Environmental Protection Agency

EPA's mission is to protect human health and to safeguard the natural environment – air, water, and land – upon which life depends. For 30 years, EPA has been working for a cleaner, healthier environment for the American people. The EPA, through its Office of Transportation and Air Quality, is responsible for the national motor vehicle air pollution program. This responsibility includes developing national standards for reducing tailpipe emissions and developing test procedures for measuring tailpipe pollution. EPA is also active in evaluating environmental performance and costs of cleaner vehicles, including alternative fuel vehicles and their fuels. EPA's National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan has recently commissioned its state-of-the-art testing center for hydrogen fuel cell vehicles and is launching a major joint "life cycle" model development project in conjunction with DOE.
