Scope 2 GHG Emissions
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. Purchased electricity is defined as electricity that is purchased or otherwise brought into the organizational boundary of the company.[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.
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]
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.
- 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.
