The U.S. Environmental Protection Agency (EPA) sets limits on how much of specific pollutants. These limits are known as the National Ambient Air Quality Standards (NAAQS). The standards help to ensure that people throughout the country have the same basic health and environmental protections. However, many U.S. cities are currently in violation of NAAQS. The primary emissions sources include on-road motor vehicles such as cars and buses; major and minor industries; and off-road motor vehicles such as construction equipment, boats, and planes. The CAAA set specific targets to reduce emissions from motor vehicles.
