On Wednesday, the Environmental Protection Agency, or EPA, finalized a regulation that will cut smog-causing air pollution from coal-fired power plants and industrial facilities. The new "Good Neighbor" rule requires 23 states to reduce nitrogen oxide emissions blowing across state boundaries. The air pollutants — which form ozone, the main ingredient in smog — can travel downwind into neighboring states, harming the health of communities miles away.
The EPA estimates the rule will halve nitrogen oxide emissions from power plants by 2027, compared to peak 2021 levels. And that cleaner air will lead to major public health improvements. According to the EPA, the new rule will prevent approximately 1,300 premature deaths, 2,300 hospital and emergency room visits, and 1.3 million cases of asthma in 2026 alone.
