Atmospheric emission factors provide a link between the electricity saved in buildings and the associated decrease in fossil fuel use in the electric supply sector. Understanding this link is important to meet the requirements of Section 1605(b) of the Energy Policy act of 1992, which established the voluntary program for reporting reductions in greenhouse gases. As part of the development process for Section 1605(b), several national workshops were held by the US Department of Energy (DOE) and the Energy Information Administration (EIA). Workshop participants expressed the need for DOE to supply default atmospheric emission facets. Based upon the response from the workshop participants, it was decided that emission factors would be aggregated to the state level (e.g., California, Connecticut, etc.). Emission factors for electricity generation are generally quantified as a quantity of impact to an amount of fuel used to produce the emission. In the electric supply sector, factors are often expressed in units of pounds or tons of emission per megawatt-hours (MWh) of electricity produced. In this paper, the authors examine and compare the estimates from three methodologies for developing state-level emission facets. In addition, they compare the results to those obtained using emissions data calculated by the EIA. Although the examples presented in this paper depict the development of state-level factors, the same methodologies can be applied by an individual utility to generate utility-specific atmospheric emission factors.
