What are the greenhouse gas and air pollutant emissions factors for fuels and electricity?

The U.S. Energy Information Administration (EIA) publishes emission factors (or coefficients) for the amounts of certain gases that are released when fuels are burned and for when electricity is generated. EIA publishes emission factors for carbon dioxide (CO2) emissions related to energy consumption and U.S. electricity generation and for sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions related to U.S. electricity generation. SO2 and NOx are not greenhouse gases, but they are criteria pollutants regulated by the U.S. Environmental Protection Agency (EPA).
