GHG Protocol
The GHG Protocol (Greenhouse Gas Protocol) establishes comprehensive global standardized frameworks to measure and manage greenhouse gas emissions from private and public sector operations, value chains, and mitigation actions.
Developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), the GHG Protocol is used by over 9 out of 10 Fortune 500 companies that report emissions.
