 missions factors
Carbon emissions factors ("carbon burdens") for
electricity for 1995-2010 are taken directly from AEO 96 (US DOE 1996),
while those for 1990 are taken from Koomey et al. (1993).1 After 1995, AEO projects that electricity carbon burdens will
remain roughly constant. Carbon burdens for other fuels are taken from US
DOE (1994b). All carbon burdens represent direct emissions and are summarized
in Table 1. Indirect emissions from the extraction, processing, and transportation
of these fuels are not included.
(1) Wood/biomass is assumed to be harvested sustainably,
resulting in zero net carbon emissions. |
