What is the Greenhouse Gas Protocol?

The GHG Protocol establishes global standards for calculating emissions across three scopes: Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy), and Scope 3 (other indirect emissions, such as supply chain and product use). It is widely used for corporate reporting, product carbon footprints, and policy development. By following the GHG Protocol, organizations can identify emissions hotspots, track progress toward climate goals, and ensure comparability and credibility of reported data.
