Air pollution can directly impact people's health and air quality is continually improving in the U.S. By virtually any measure, the air we breathe is cleaner today than just a few short decades ago. This is thanks in large part to the federal Clean Air Act, which was passed about 30 years ago and has subsequently been strengthened and improved. Emissions of many harmful pollutants have been cut in half since the law was passed.

Cars, trucks, buses, equipment, factories, power plants, and businesses all contribute to air pollution. The Clean Air Act allows EPA, working with its state and local partners, to place limits on pollution from these and other sources of pollution.
