the air quality health standard for ground-level ozone, or smog.

Less smog means: fewer lives lost too soon -fewer asthma attacks -fewer emergency room

visits -fewer sick days for working families and schoolchildren.

We reviewed thousands of scientific studies, and set the standard based on what the science

tells us is necessary to protect the health of Americans.

That means kids, older adults and people with asthma or other lung diseases can breathe

easier. Most U.S. counties that monitor their air

will meet the new standard by 2025 as cars and factories cut pollution.

Clean air and a healthy environment help to strengthen our economy. Since 1970, our country

has worked to cut air pollution by 70%, and at the same time our economy tripled in size.

The bottom line: Stronger ozone standards mean less smog, cleaner air and a healthier

future for generations to come.
