Power Plant Emission Trends

EPA collects detailed sulfur dioxide (SO2), nitrogen oxides (NOX), and carbon dioxide (CO2) emission data and other information from coal-fired power plants across the country. Collected as part of the Acid Rain Program (ARP) and the Clean Air Interstate Rule (CAIR), these data are available online, making it easy for the public to understand emissions from these sources and to see when and where emission changes have occurred.
