Please see www.epa.gov/airtrends for the latest information on Air Quality Trends.

Since EPA was established in 1970, air quality in the U.S. has improved tremendously. Many of these improvements can be attributed to pollution control programs instituted under the Clean Air Act, State and local laws, and actions by industry. A gathering of people. Because air pollution problems continue in many parts of the country, EPA and States continue to seek innovative and more cost-effective programs to further reduce emissions. Market-based programs like emissions trading provide incentives for industry to develop new pollution control technologies or pollution prevention approaches. Through continued partnership with the regulated community, environmental groups, State, Tribal, and local governments, and concerned citizens, EPA is working to develop effective common-sense control strategies to improve our nation's air quality.
