The GHG Protocol provides the most widely used accounting standards for greenhouse gases worldwide.

 

In 2016, 92 % of the Fortune 500 companies that responded to the CDP used the GHG Protocol directly or indirectly through a GHG Protocol-based program. It provides an accounting platform for virtually every corporate greenhouse gas reporting program in the world.

The popularity of the GHG Protocol standards is due in part to the extensive outreach and stakeholder consultation facilitated by WRI and WBCSD during each standards development project. (More on ghgprotocol.org)
