Clean Air Markets (Coal Data)

The Clean Air Markets Program Division (CAMD), or simply "Clean Air Markets," answers scientific, general, policy, and regulatory questions about industry emissions. The program is designed to improve air quality and ecosystems by lowering outdoor concentrations of fine particles, mercury, ozone, and other significant air emissions. The most well-known of these programs are EPA's Acid Rain Program and the NOx Budget Trading Programs, which reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)-- compounds produced by fossil fuel combustion.

TOXMAP's coal data includes all facilities in all programs covered in the AMPD's 2017 database whose primary or secondary fuel type is coal-related (e.g., Coal, Coal Refuse, and Petroleum Coke).

According to the US Energy Information Administration (EIA), in 2017, the United States generated about 4,015 billion kilowatt-hours of electricity at utility-scale facilities. About 62.7% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 30.1% attributed from coal.

According to the US Energy Information Administration (EIA), the total US energy-related emissions of carbon dioxide (CO2) by the electric power sector in 2016 were 1,821 million metric tons, or about 35% of total US energy-related CO2 emissions.

About 1,241 million metric tons of carbon dioxide emissions were attributable to electricity generated from coal.
