Millions of Americans Breathing Unhealthy, Polluted Air

More than 4 in 10 Americans — nearly 138.5 million people — live in counties where ozone or particle pollution levels make the air unhealthy to breathe. Our 16th annual “State of the Air” report, released this week, shows the nation’s air quality has improved in some places — but not everywhere.

What's Changed?

Overall, thanks to cleaner power plants and cleaner diesel fuel and engines, most air quality progress was made in the eastern half of the nation with the continued reduction of year-round particle pollution. Particle pollution was recently found to cause lung cancer, adding another reason that cleaning these sources of pollution will save lives.

This year’s report also provides evidence that a changing climate will make it harder to protect human health from the dangers of air pollution. The impact of climate change is particularly apparent in the western United States, where heat and drought create situations ripe for episodes of high particle pollution. Some cities had worse ozone pollution, as warmer temperatures make cleaning up ozone even harder.
