Scope 2 GHG Emissions
Contents
Definition
Scope 2 GHG Emissions. Indirect GHG Emissions from the generation of purchased or acquired electricity, steam, heating, or cooling consumed by the reporting company or other entity. Scope 2 emissions physically occur at the facility where electricity is generated.[1]
Context
Scope 2 emissions represent one of the largest sources of GHG emissions globally. The generation of electricity and heat now accounts for at least a third of global GHG emissions. Electricity consumers have significant opportunities to reduce those emissions by reducing electricity demand, and increasingly play a role in shifting energy supply to alternative low-carbon resources (See Sustainable Electricity)
- Scope 2 emissions physically occur at the facility where the electricity, steam, heating, or cooling is generated.
- Scope 2 GHG emissions will primarily be calculated from metered electricity consumption and supplier-specific, local grid, or other published emission factors.
Specific Protocols
Corporate Protocol
To calculate scope 2 emissions, the Corporate Standard recommends multiplying activity data (MWhs of electricity consumption) by source and supplier-specific emission factors to arrive at the total GHG emissions impact of electricity use. Concrete methods:
City Protocol
GHG emissions occurring as a consequence of the use of grid-supplied electricity, heat, steam and/or cooling within the city boundary.[2]
