Across the United States, a handful of coal- and gas-fired power plants account for a disproportionate share of the nation’s air pollution. These facilities release millions of tons of carbon dioxide every year, along with harmful particulate matter and nitrogen oxides that drift downwind into surrounding communities.

While the health risks of air pollution are national in scope, certain counties sit directly in the path of the country’s largest and dirtiest power plants. As the EPA works to roll back dozens of regulations on emitters, downwind communities are particularly at risk of respiratory illness, heart disease, and premature death. A closer look at the data reveals where the most Americans are at risk from power plant emissions.

To determine where the most Americans are at risk from power plant emissions, Climate Crisis 247 reviewed data on power plant emissions from the EPA. Power plants were ranked based on total annual carbon dioxide emissions. Supplemental data on annual particulate matter emissions, nitrogen oxides emissions, and downstream population impacted by each power plant are also from the EPA. Estimates for the downstream population impacted by each power plant’s emissions are based on the EPA’s Power Plants and Neighboring Communities Mapping Tool.
