S&P Global Sustainable 1 performed this analysis to determine Scope 1 and 2 emissions from NuScale Power’s operations based on the greenhouse gas accounting standard: GHG Protocol
Headquartered in Portland, Oregon
NuScale Power is a nuclear power plant company specializing in the engineering and design of small modular reactors
Under the market-based approach, total GHG emissions for FY2022 was 219 tCO₂e with Scope 2 emissions accounting for 94% of the whole and Scope 1 for the remainder.
Total stationary energy use – including fossil fuel used for direct operations and purchased electricity – accounted for 100% of Scope 1 and 2 emissions, while mobile emissions – typically generated by company vehicles – accounted for 0% of emissions.
Under the location-based approach, the total GHG emissions for FY2022 was 252 tCO₂e. 95% of those total GHG emissions belong to Scope 2, while the remaining 5% belongs to Scope 1 emissions.
NuScale Power’s Scope 1 and Scope 2 GHG emissions assessment is consistent with the GHG Protocol

A range of data for an operational footprint analysis including information on operational and vehicle fuel use data, electricity data, data on refrigerant leaked, water consumption and waste generation. Data provided by NuScale Power covers 100% of the sites’ full-time employees (FTEs). Data received from NuScale Power are:
o Operational fuel use – Natural gas o Electric consumption sourced from the power grid
The Greenhouse Gas Protocol methodology for compiling GHG data was used to assess the carbon footprint. This includes the following material GHG: CO₂ (carbon dioxide), N2O (nitrous oxide) and CH4 (methane).
o Fossil fuel emission factors (Scope 1 – Stationary and mobile): EIA 2021 o Purchased electricity US: IEA 2021
The following emission conversion factor sources are used in calculations:

According to the GHG Protocol Scope 2 Guidance released in January 2015, corporations are now to report two Scope 2 emission totals – location-based and market-based, known as ‘dual reporting’. Since market-based emission factors (such as renewable energy certificates, supplier emission factors or other tracking mechanisms) are not available to any of NuScale Power’s locations, residual emission factors were adopted where available. Future calculations shall be updated upon the release of residual factors for public use. Residual emissions factors represent the emissions that remain after certificates, contracts and supplier specific factors have been removed from the grid emissions factor calculation.

Scope
NuScale Power’s Scope 2 emissions calculated using market-based approach are 206 tCO₂e, 14% lower than location-based. In this case, the regions where NuScale Power operates have lower residual emission factors than the United States IEA standard.

Emissions (tCO₂e)
The table below relates the key findings for environmental impacts resulting from NuScale Power’s operations. GHG emissions are normalized by total revenues ($11.8m USD) and total employees (556), resulting in a GHG intensity of 21.3 tCO₂e/mUSD and 0.45 tCO₂e/employee, respectively.

Direct (Scope 1) GHG Emissions
Direct emissions are GHG emissions from organizational operations (or Scope 1) derived from propane, diesel, natural gas consumption for boiler, gas turbine, diesel generators, owned transportation and refrigeration processes. NuScale Power’s Scope 1 emissions are from fuel usage in office buildings and is in magnitude of 12.8 tCO₂e.
Indirect emissions are GHG emissions from the consumption of purchased electricity (or Scope 2). NuScale Power’s Scope 2 emissions (location-based) during FY2022 were 239.0 tCO₂e. 100% of the electricity was purchased from the grid.

Description
Term
According to the GHG Protocol 2 Guidance released in January 2015, companies are required to report Scope 2 emission totals – location-based and market-based, known as ‘dual reporting.’
Dual reporting
GWP is the ratio of the warming of the atmosphere caused by one substance to that caused by a similar mass of carbon dioxide, which is assigned a reference value of 1.
Global warming potential (GWP)
Emission intensity is the level of GHG emissions per unit of economic activity, such as million revenues or number of employees.
Emission intensity
A location-based method reflects the average emissions intensity of grids on which energy consumption occurs (using mostly gird-average emission factor data).
Location-based methodology
Gases that trap heat in the atmosphere care called greenhouses gases.
Greenhouse gases
Residual emission factor
A market-based method reflects emissions from electricity that companies have purposefully chosen (or their lack of choice). It derives emission factors from contractual instruments, which include any type of contract between two parties for the sale and purchase of energy bundled with attributes about the energy generation, or for unbundled attribute claims. Markets differ as to what contractual instruments are commonly available or used by companies to purchase or claim specific attributes about it, but they can include energy attribute certificates (RED, GOs, etc.), direct contracts (for both low-carbon, renewable, or fossil fuel generation), supplier-specific emission rates, and other default emission factors representing the untracked or unclaimed energy and emissions (termed the residual mix).
Market-based methodology
Glossary (continued)
Scope 1 includes direct emissions from sources, which a company owns, or controls. This includes direct emissions from fuel combustion and industrial processes.
Scope 2 covers indirect emissions relating solely to the consumption of electricity that is purchased by the owned or controlled equipment or operations of the company. Scope 2 emissions are reported in both location-based and market-based approach in alignment with the latest GHG Protocol guidance.
These emissions results from combustion of fuels in stationary sources, e.g., boilers, furnaces, turbines.
Scope 1 - stationary combustion emissions
Scope 3 covers other indirect emissions including third-party provided business travel and purchased goods and services.
Scope 3
These emissions result from the combustion of fuels in company owned/controlled mobile combustion sources (e.g., trucks, trains, ships, airplanes, buses, and cars). These vehicles can be used for transportation of materials, products, waste, and employees.
Scope 1 mobile emissions
Emissions not caught by a capture system which are often due to equipment leaks, evaporative processes and windblown disturbances. For example, emission from refrigerants.
Scope 1 fugitive emissions
