Topics: Healthy Air GASP and the Breathe Project are organizations working to improve air quality in Pittsburgh, Pennsylvania. This guest blog represents the views of the authors. Last month, the American Lung Association’s annual “State of the Air” report found that Allegheny County, Pennsylvania—the home of Pittsburgh—was one of only 13 counties in the United States to earn failing grades for long and short-term exposure to fine particulate matter (PM 2.5) and ground-level ozone. Despite the 2021 report noting the best scores the Lung Association has ever calculated for our region, these low rankings are a stark reminder that significant work remains to be done.
