Nevada Statewide Greenhouse Gas Emissions Inventory and Projections
Nevada Statewide Greenhouse Gas Emissions Inventory and Projections, 1990 to 2030
replaced with newer models, the fleet will emit less CO2 per vehicle as a whole and grow cleaner.
However, even though the fleet continues to grow cleaner on a per vehicle basis, this is counterbalanced
by an increasing number of vehicles on Nevada's highways and higher AVMT, which may contribute to a
growth in emissions.

Projected Emissions
Total sector emissions in 2030 are projected to increase to 16.698 MMTCO2eq, which is still lower than
the sector's 2007 high. Figure 4-3 shows the historical and projected emissions estimates from the
transportation sector from 1990 to 2030. The dashed vertical line in the figure shows where the
historical period ends and the projections begin. The sector will remain largely flat in terms of emissions
over the projected period with the overwhelming majority of emissions coming from CO2 based sources
such as motor gasoline, distillate fuel, and jet fuel/kerosene. This stands to reason when considering the
advances in vehicle technologies that will likely lead to the automotive industry meeting the EPA's
Model Year 2022 to 2025 average 54.5 miles per gallon fuel economy standard. Decreases in fleet-wide
fuel consumption will proportionally reduce CO2 emissions, which will be offset by projected increases to
the state's population and subsequent increases in numbers of vehicles and VMT.
