U.S. city air pollution dropped 18% in five years due to stricter rules and more electric vehicles, but rural areas still face high levels.
A new study released on November 20, 2025, reveals that air pollution levels in major U.S. cities have decreased by 18% over the past five years, attributed to stricter emissions regulations and increased use of electric vehicles.
The Environmental Protection Agency reports that the decline is most pronounced in urban areas with expanded public transit and renewable energy adoption.
While progress is noted, officials caution that rural regions still face elevated pollution levels due to agricultural and industrial activity.
