77 Percent Cleaner
Over the last 35 years, America’s coal-based electricity providers have invested more than $50 billion in technologies to reduce emissions. Due to investments like these, our coal-based generating fleet is more than 77 percent cleaner on the basis of regulated emissions per unit of energy produced.

The calculations are based on five pollutants: carbon monoxide, volatile organic compounds, sulfur dioxide, nitrogen oxide and particulate matter. The data from the U.S. Environmental Protection Agency reflects the environmental performance per unit of energy produced. That is, the relationship of emissions per billion kilowatt-hours. From 1970 to 2005, the value for that ratio fell from 30,510 short tons per billion kilowatt-hours to just 6,970 short tons per billion kilowatt-hours — a reduction of 77.15 percent.
* We did not track emissions of less than 100 tons per year; all other emission figures on this table are reported in thousands of short tons.
