Projected Emissions
Projected emissions in this sector were based on the assumption that growth in this sector would largely
resemble recent historical trends in changes to livestock populations, agricultural soils, and agricultural
residue burning. The methods presented in the SIT were applied to forecasted livestock populations in
order to estimate emissions. Emissions from both enteric fermentation and manure management are
dependent on livestock populations. Forecasted changes to livestock populations based on post-
recession totals show that there will be very little growth in Nevada's population of livestock.
Forecasting the emissions from the agricultural soils and agricultural residue burning sub-sectors shows
similar results. The data from these forecasts show a relatively insignificant source of CO2 emissions in
the state will grow by roughly 12 percent by 2030. This increase equates to less than half of a percent of
Nevada's 2030 emissions.
The projections show that total GHG emissions from the agricultural sector will increase by about
200,000 metric tons of CO2eq in 2030 (versus 2013 figures). Agricultural sector emissions are not
projected to surpass the maximum total emissions that this sector achieved in 2001. Overall, these
projections show that this sector will continue to be a minor contributor of GHGs in the state. Figure 8-3
shows the historical and projected emissions from the agricultural sector. The vertical dashed line
marks the end of historical emissions and the beginning of the projections.
