More than 4 in 10 people live in counties with unhealthy air, according to the Lung Association's 2022 "State of the Air" report. Under the Clean Air Act, there are national limits in place on many outdoor air pollutants, including particle pollution, called the National Ambient Air Quality Standards (NAAQS.) But the latest science shows that the current limits are too weak—leaving the health of millions at risk.
Right now, the U.S. Environmental Protection Agency is considering strengthening the particle pollution NAAQS. If they follow current science and strengthen the standards, the whole country could see immense health benefits.
Health Professionals: Call for Stronger Soot Standards
Health professionals see firsthand the health impacts of air pollution. Through partnership with the Medical Society Consortium on Climate and Health, we asked health professionals to share their stories and to call on EPA to strengthen particulate matter standards.
