Between 1990 and today, coal plants have reduced emissions by 99.8 percent in America.
That figure reflects a major shift in how coal is burned and regulated.
Sulfur dioxide, nitrogen oxides, and particulate matter have been sharply cut through scrubbers, filters, and tighter standards.
In the United States, these controls became widespread after amendments to the Clean Air Act in 1990.
Utilities invested billions to retrofit aging fleets while maintaining output.
Air quality improved across many regions as a result.
