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 and frequently the most significant opportunity to reduce these emissions.
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]
