Scope 2 emissions are indirect greenhouse gas emissions that result from the generation of purchased electricity, heat, or steam that you may consume as part of your business operations. They are considered indirect because the emissions occur from activities outside of the organisation's control, but are still relevant to the organisation's overall carbon footprint. You will usually find the following emission categories defined as per the GHG Protocol:
Purchased electricity
Purchased heat
Purchased steam (currently not supported)
Purchased cooling (currently not supported)
If you intend to report your emissions based on a particular standard or framework, measuring scope 2 emissions is typically required.
