Scope 2 Emissions
In the Greenhouse Gas Protocol (GHGP), Scope 2 Emissions are a result of a company’s activities but often occur outside a company’s physical facility (e.g. at an electricity utility plant), hence scope 2 emissions are considered an indirect emission source.
Scope 3 Emissions
Scope 3 emissions are the result of activities from assets not owned or controlled by the reporting organization, but that the organization indirectly affects in its value chain. An organization’s value chain consists of both its upstream and downstream activities.
