Acid Rain
Air Quality Shows Continued Improvement
[September 15, 2003] New acid rain data, as well as
EPA's Annual Air Trends Report, both released today, show steady and significant air quality improvement.
This environmental progress comes even as the country has experienced a 164 percent increase in gross domenstic
product, a 42 percent increase in energy consumption and a 155 percent increase in vehicle miles traveled.

Acid rain is a serious environmental problem that affects
large parts of the U.S. and Canada. This section of the Web site provides
information about acid rain's causes and effects, how we measure acid rain,
and what is being done to solve the problem under EPA's Acid Rain Program.
The Acid Rain Program, run by the Clean Air Markets Division, requires major
reductions of sulfur dioxide and nitrogen oxide emissions (the key components
of acid rain) from electric utilities, while establishing a new approach
to environmental protection through the use of market incentives. This nationwide
cap-and-trade method of regulation has resulted in significant environmental
progress and cost savings, focusing worldwide attention on the Acid Rain
Program model.
