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. 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 commonsense
control strategies to improve our nation's air quality.
