Scope 1 emissions

Scope 1 emissions are defines as Greenhouse Gas Emissions from operations that are owned or controlled by the reporting company.

Scope 1 emissions are direct emissions from sources owned or controlled by a reporting entity within its reporting boundary (refer to the reporting boundary, which is a combination of a reporting entity’s selected organizational and operational boundaries). Common examples include emissions from fuel combustion at entity-owned production plant generators or fuel emissions from entity-owned or entity-controlled vehicles.

The GHG Protocol requires a reporting entity to differentiate its GHG emissions from direct and indirect sources (i.e., Scope 1 vs. Scope 2 and Scope 3), but it does not require a reporting entity to report on Scope 3 emissions (see section 1.5). However, some regulations may require it to report Scope 3 emissions. This accounting and reporting structure increases the transparency of the emissions based on which party is emitting the GHGs. It also avoids double counting by making sure that two or more reporting entities do not account for the same emissions in Scope 1, while also providing information about a reporting entity’s other GHG emissions. That is, if every entity and individual throughout the world reported their GHG emissions, the total of all Scope 1 emissions would equal the total GHGs emitted throughout the world.

However, a stakeholder may also want information about how a reporting entity’s decisions (e.g., how much purchased electricity its production process uses, the impact of business travel) affects GHG emissions, which is why reporting entities also report their indirect GHG emissions in Scope 2 and Scope 3 emissions.
