Nearly half of US children are breathing dangerous levels of air pollution, report warns

American Lung Association report comes amid Trump EPA's expansive rollback of environmental protections

Nearly half of children in the United States are breathing dangerous levels of air pollution, according to a new report, as experts warned Donald Trump's expansive rollback of protections will make the situation worse.

The 27th annual air quality report from the American Lung Association (ALA) released on Wednesday evaluates pollution across the country by grading levels of ground-level ozone - also known as smog - as well as year-round and short-term spikes in particle pollution, commonly referred to as soot. The report analyzed quality-assured data collected between 2022 and 2024.
