The Greenhouse Gas (GHG) Protocol

The Greenhouse Gas (GHG) Protocol categorises carbon emissions into three ‘Scopes’:

Scope 1 – Direct GHG emissions that occur from sources owned or controlled by the organisation.

Scope 2 – Indirect GHG emissions from generation of purchased electricity consumed by the organisation.

Scope 3 – Other indirect GHG emissions that occur as a consequence of the activities of the organisation, but occur from sources not owned or controlled by the organisation.
