Note(s): 1) Emissions assume complete combustion from energy consumption, excluding gas flaring, coal mining, and cement production. The combustion of fossil fuels produces carbon in the form of carbon dioxide and carbon monoxide; however, carbon monoxide emissions oxidize in a relatively short time to form carbon dioxide. 2) Coefficients do not match total emissions reported in the AEO 2011 Early Release and were adjusted using Assumptions to the AEO 2010. 3) Excludes electricity imports from utility consumption. Includes nuclear and renewable (including hydroelectric) generated electricity. 4) This coefficient is used to estimate CO2 emissions resulting from the consumption of energy by electric generators. 5) This coefficient is used to estimate CO2 emissions resulting from the consumption of electricity by end-users. 6) This coefficient is used to estimate emissions of the next-built (2010) natural gas-fired, electric generator resulting from the consumption of electricity by end-users. 7) This coefficient is used to estimate emissions of existing natural gas-fired, electric generators resulting from the consumption of electricity by end-users.
