Nevada Statewide Greenhouse Gas Emissions Inventory and Projections

Nevada Statewide Greenhouse Gas Emissions Inventory and Projections, 1990 to 2030 Total Nevada emissions have increased 25 percent since 1990 but have decreased 27 percent from the 2005 peak. In general, a correlation exists between population growth and GHG emissions. For example, the increase in GHG emissions from 1990 to 2005 closely follows the Nevada's population growth during the same period. However, disregarding changes in population, large changes in GHG emissions can also occur as a result of changes in production technologies or methodologies that release GHGs. For example, the large decline in GHG emissions after 2005 resulted from the retirement of Mohave Generating Station, a coal-fired power plant. A similar situation, though with far less impact, occurred more recently in the waste management sector. With the installation of landfill-gas-to-energy technology (a process which converts CH 4 biogas into electricity) at Nevada's largest landfill, emissions in the sector were reduced by more than 500,000 MTCO2eq (a nearly 22 percent decrease in emissions). Table ES-1 provides a sector-by-sector summary of GHG emissions in Nevada for select years from 1990 to 2013.

These emissions projections consider estimates of future emissions as well as known changes to a sector. Figure ES-2 shows Nevada's GHG emissions from 1990 to 2030 with a dashed vertical line separating where the historical period ends and the projections begin. Between 2014 and 2030 the transportation sector is expected to become the largest source of GHG emissions in the state. Total emissions statewide will remain relatively flat between 2013 and 2030 where emissions are projected to increase by less than 1 MMTCO2eq. This is due, in part, because as Nevada continues to move away from coal-fired electricity generation, emissions in the electricity generation sector will continue to decline. viii
