1Emission factors for coal used for electricity generation are specified by coal supply region and types of coal, so the average carbon dioxide contents for coal varies throughout the forecast. The 2000 average is 25.50. Source: Energy Information Administration, Emissions of Greenhouse Gases in the United States 2000, DOE/EIA-0573(2000), (Washington, DC, November 2001). |
