Projected Emissions
Residential, commercial, and industrial sector emissions projections were calculated using the SIT.
Through the utilization of EIA-SEDS fuel consumption projections, the SIT projects GHG emissions. It
also utilizes EIA fuel-specific carbon coefficients that are paired with corresponding combustion
efficiencies. The one drawback to this approach is that it does all of this in a top-down fashion. That is,
the EIA-SEDS (and the SIT projection tool) project fuel consumption on a multi-state "regional" level and
disaggregates the results back to the states by comparing the populations and GDPs of the states in the
region. The result, in this instance, is to project that Nevada emissions will be immediately reduced by
more than 1 MMCO2eq and then not reach 2013 levels again before 2030. Figure 5-3 illustrates the
historical and projected emissions estimates from the residential, commercial, and industrial sectors
from 1990 to 2030. The dashed vertical line shows where the historical period ends and the projections
begin. Once again, the SIP projection tool creates a reduction in emissions that NDEP does not believe is
accurate. Unfortunately, there is no better way to estimate future emissions in this sector. The only
significant trend in these projections is that sector emissions will continue to rise. Total sector emissions
in 2030 are projected to be 6.420 MMTCO2eq which is less than the 2013 estimate of 6.807 MMTCO2eq.
