Each reporting year, your organization should measure all the fuels and energy being consumed by your assets. By specifying the ownership and boundary of each asset, you can measure all the GHG types across Scope 2 after applying the correct allocation.

Scope 2 emissions are indirect GHG emissions associated with the purchase of electricity, steam, heat, or cooling. While scope 2 emissions occur at the facility where they are physically generated (power plants or heating units), they are often accounted for in an organization’s GHG inventory because they are a result of that organization’s energy consumption.
Usually either purchased (in kWh or MWh) from a utility or an energy supplier. Onsite combustion of fossil fuels to convert to electricity via plants owned by the organization will be counted as their stationary combustion, and thus scope 1.
The reporting organization shall report the following information:
a. Gross location-based energy indirect (Scope 2) GHG emissions in metric tons of CO2 equivalent.
[…] disclose its absolute gross greenhouse gas emissions generated during the reporting period, expressed as metric tonnes of CO2 equivalent […] classified as […] Scope 2 greenhouse gas emissions […]
[…] disclose its location-based Scope 2 greenhouse gas emissions […]
CDP C6.2 - Describe your organization's approach to reporting Scope 2 emissions.
CDP C6.3 - What were your organization's gross global Scope 2 emissions in metric tons CO2e?
CDP C7.7a - Break down your gross Scope 1 and Scope 2 emissions by subsidiary.
CDP C7.9b - Are the reported emissions performance in sections C7.9 and C7.9a based on a location-based Scope 2 emissions figure or a market-based Scope 2 emissions figure?
The reporting organization shall report the following information:
b. If applicable, gross market‑based energy indirect (Scope 2) GHG emissions in metric tons of CO2 equivalent.
[…] the entity shall […] provide information about any contractual instruments the entity has entered into that is necessary to inform users’ understanding of the entity’s Scope 2 GHG emissions
[…] Various types of contractual instruments are available in different markets and the entity might disclose information about its market-based Scope 2 greenhouse gas emissions as part of its disclosure.
GHG scope 2 emissions generated by the asset, calculated using the location-based method (ghg_abs_s2_lb_w) and the Total floor area where GHG scope 2 emissions can exist, calculated using the location-based method (ghg_tot_s2_lb_w).
- Covered floor area where GHG scope 2 emissions data is collected, calculated using the location-based method (ghg_cov_s2_lb_w). GHG scope 2 emissions generated by the outdoor spaces associated with the asset, calculated using the location-based method (ghg_abs_s2_lb_o).
- GHG scope 2 emissions generated by the asset, calculated using the market-based method (ghg_abs_s2_mb_w) including GHG scope 2 emissions generated by the outdoor spaces associated with the asset, calculated using the market-based method (ghg_abs_s2_mb_o).
Usually purchased from a supplier in weight or BTUs, often with power generation. Steam capacity is often transferred for use in buildings, such as for cooking, but also industrial applications in turbines. If the combustion leading to the steam is conducted in equipment owned by the organization, the fuel source being used would be counted as their scope 1 emissions.
Usually purchased from a supplier in weight or BTUs, often with power (co)generation. The heat generated in such centralized locations is distributed through a system of insulated pipes for a buildings’ heating requirements such as space heating and water heating. If the biomass, fossil-fuel or renewable energy-based co-generation plant is owned by the organization, the fuel usage will be reported as their scope 1 stationary emissions.
A district cooling system uses water chilled by cooling plants (chillers or residual heat for cooling) which travels from the upstream plant to the organizations’ buildings to cool the space. Fossil or renewable feedstock used in these systems, if owned by the organization, would be reported as their scope 1 emissions.
Scope 2 Emissions - Indirect GHG emissions that result from the consumption of purchased electricity, steam, heat, or cooling. For example, if a company purchases electricity from a utility that generates electricity using coal, the Scope 2 emissions associated with that purchased electricity would be the emissions from the coal-fired power plant. If your electricity comes from a clean source like nuclear energy, then your Scope 2 emissions will be significantly lower.
To reduce SCOPE 2 emissions, you can take the next step toward reaching true zero emissions by using:
- Electricity supply that is sourced 100% from carbon-free power,
- 24/7 real-time carbon-free energy matching.
- Emission-Free Energy Certificates (EFECs)
- Renewable Energy Certificates (RECs).
