GHG Protocol

The Corporate Standard classifies a company’s direct and indirect GHG emissions into three “scopes,” and requires that companies account for and report all scope 1 emissions (i.e., direct emissions from owned or controlled sources) and all scope 2 emissions (i.e., indirect emissions from the generation of purchased energy consumed by the reporting company). The Corporate Standard gives companies flexibility in whether and how to account for scope 3 emissions (i.e., all other indirect emissions that occur in a company’s value chain).

Relationship between a scope 3 GHG inventory and a product GHG inventory (for a company manufacturing Product A)

Direct emissions are included in scope 1. Indirect emissions are included in scope 2 and scope 3. While a company has control over its direct emissions, it has influence over its indirect emissions. A complete GHG inventory therefore includes scope 1, scope 2, and scope 3.
