America’s Most Polluted Cities

Annual Report Shows Both Positive Trends and Continuing Threats

(April 27, 2011)

We all have to breathe. But according to the American Lung Association’s 12th annual State of the Air report, where you live has a big impact on whether or not the air you breathe is healthy or hazardous.

The American Lung Association has released our 12th annual report on air quality, State of the Air 2011. State of the Air 2011 takes a close look at air quality across the country, and finds both good and not-so-good news. The report assigns grades for two important types of air pollution - ozone (smog) and particle pollution (soot) - and lists America’s most polluted cities. Is your city on the list? Find out here.

New features in this year’s report allows you to see how your city ranks and how the air has improved—or not—over the years. You can even compare the air in your city to another city.

Steady Progress
This year’s report found that the majority of American cities that are most-polluted by ozone or year-round particle pollution have improved their air quality, showing continued progress in the cleanup of deadly toxics. Credit for this goes to the Clean Air Act.

State of the Air tells us that the progress the nation has made cleaning up coal-fired power plants, diesel emissions and other pollution sources has drastically cut dangerous pollution from the air we breathe,” said Charles D. Connor, American Lung Association President and CEO. “We owe our cleaner air to the Clean Air Act. We have proof that cleaning up pollution results in healthier air to breathe. That’s why we cannot stop now.”

Threats to Continued Progress
Despite the Clean Air Act’s 40 years of success in improving our air, some members of Congress are now proposing changes to the law that would weaken this safeguard. You can join our fight to protect the Clean Air Act, so the law can continue defending our health.  Learn more.

Efforts to weaken this vital public health law pose real threats to half the nation - the 154.5 million people who still live in areas with levels of ozone and/or particle pollution that are often dangerous to breathe. State of the Air 2011 finds that eighteen million people live where air pollution failed every test.
