More than 1 in 3 people live in counties with unhealthy air, according to the Lung Association's 2023 "State of the Air" report. Under the Clean Air Act, there are national limits in place on many outdoor air pollutants, including particle pollution and ozone, called the National Ambient Air Quality Standards (NAAQS). Updating those limits in accordance with the latest health science, and then implementing and enforcing those stronger standards, is critical for lung health.
The good news is the U.S. Environmental Protection Agency (EPA) recently strengthened the national standards for particle pollution (also called soot). While we called for even more protective levels than what EPA finalized, these stronger standards will result in real health benefits.
Unfortunately, EPA is delaying its actions on ozone (also called smog) even though the health science shows that much stronger ozone limits would prevent asthma attacks and save lives.
We need your help. Join us in thanking EPA for final soot standards and calling on them to speed up their work to set stronger ozone standards.
