Mobile source emissions, or emissions from motor vehicles and non-road engines, account for almost a third of the air pollution in the United States. Routine aging and deterioration of vehicles, poor state of tune, and emission system tampering all increase emissions.

These emissions, primarily hydrocarbons and nitrogen oxides, contribute to the formation of ground level ozone, a noxious pollutant considered this country’s most pressing urban air quality problem.

To reduce vehicle emissions, the U. S. Environmental Protection Agency (EPA) has enacted several new emission standards for new vehicles. These standards address emissions from passenger cars, light trucks, and heavy-duty diesel and gasoline-powered vehicles. In addition, EPA recently began to address emissions from non-road equipment like ships and locomotives. These new standards will, in time, improve air quality throughout the United States.
