Top 10 Cleanest Cities in the U.S. by Clean air 2017

The air Americans breathe is cleaner than ever, thanks to cleaner power plants and cleaner vehicles. That milestone is all the more impressive when considering progress has been achieved in spite of increases in population, energy use, and miles driven.

Yet nearly 40 percent of Americans—125 million people—still live where the air is unhealthy to breathe. Those findings are contained in the American Lung Association’s annual State of the Air report, released Wednesday.

This year’s survey tracks air quality measurements between 2013 and 2015 of ozone and particle pollution, short-term and year-round. Cities and counties are ranked on three separate lists for levels of those pollutants. More than 18 million people live in 12 counties with all three air pollution conditions.

Ozone, otherwise known as smog, is created by gases, including tailpipe and smokestack emissions. People at risk from inhaling ozone are children, teens, seniors age 65 and older, people who work outdoors, and people with heart and lung diseases, including asthma and lung cancer.

Places you can breathe easy

Forty years after the Clean Air Act, more people are breathing easier. "In general, we’ve seen tremendous improvement in air quality," says Jonathan M. Samet, MD, director of the Institute for Global Health at the University of Southern California, in Los Angeles.
