Nevada Statewide Greenhouse Gas Emissions Inventory and Projections
Nevada Statewide Greenhouse Gas Emissions Inventory and Projections, 1990 to 2030
5. Residential, Commercial, and Industrial
5.1
Overview
This section summarizes the GHG emissions associated with the burning of fuels in the residential,
commercial, and industrial sectors. Industrial Process emissions, that is, emissions associated with the
transformation of raw materials from one state to another that results in the release of GHGs into the
atmosphere, is discussed in Section 6. The GHG emissions accounted for in this sector are CO2, CH4, and
N₂O. Emissions are generally calculated by applying specific emission factors (expressed in mass of
carbon per unit of energy content, e.g. lbs GHG/BTU) and combustion efficiency (expressed in
percentages) to the different types of fuels consumed in each sector. Table 5-1 lists the types of fuel
consumed by each sub-sector.

The SIT also takes into account that some industrial processes (e.g., road asphalting or synthetic rubber
production) consume fossil fuels (e.g., oil or LPG) in a manner that permanently stores that fuel into the
final product with no emissions into the atmosphere. The SIT provides emission factors, energy content,
combustion efficiencies, and the fractions of permanently stored fuels. Fuel consumption data was
provided by the EIA-SEDS.25

State Inventory Tool, ICF International, Prepared for U.S. Environmental Protection Agency. February 2016, p 1.6.
24 Some fuels that are considered by the SIT are not included in this table as there was zero consumption in Nevada
over the 1990 to 2013 period.

It is important to note that the way the EIA-SEDS disaggregates fossil-fuel can result in under/overestimates of
emissions versus the other states in the original "group". This is due to the methods of redistribution which are
largely comparisons of populations and in some cases gross domestic products (GDPs).
