Motor Vehicles and Diesel-Powered Equipment
Consumer Information
Mobile sources are motor vehicles, engines, and equipment that move, or can be moved, from place to place. Mobile sources include vehicles that operate on roads and highways ("on-road" or "highway" vehicles), as well as nonroad vehicles, engines, and equipment. Examples of mobile sources are cars, trucks, buses, earth-moving equipment, lawn and garden power tools, ships, railroad locomotives, and airplanes.
Emissions from an individual car are generally low, relative to the smokestack image many people associate with air pollution. But in numerous cities across the country, the personal automobile is the single greatest polluter, as emissions from millions of vehicles on the road add up. Driving a private car is probably a typical citizen’s most “polluting” daily activity.
Below you will find some useful information that will help you understand more about your car's impact on the environment and make decisions to lessen that impact.

Reducing Diesel Emissions
Reducing emissions from diesel engines is one of the most important air quality challenges facing the country. Even with more stringent heavy-duty highway engine standards set to take effect over the next decade, over the next twenty years millions of diesel engines already in use will continue to emit large amounts of nitrogen oxides and particulate matter, both of which contribute to serious public health problems. These problems are manifested by thousands of instances of premature mortality, hundreds of thousands of asthma attacks, millions of lost work days, and numerous other health impacts.
Building on the successes of EPA’s regulatory and non-regulatory efforts to reduce emissions from diesel engines, EPA has created the National Clean Diesel Campaign (NCDC). The Campaign will work aggressively to reduce the pollution emitted from diesel engines across the country through the implementation of varied control strategies and the aggressive involvement of national, state, and local partners.

EPA's Breathing Clean by Building Green: Clean Diesel Construction
video chronicles how retrofit technologies have been used on several notable construction projects to reduce emissions from construction equipment. Told from several perspectives, this video illustrates how organizations can work in partnership to reduce diesel emissions and protect public health.
