The Greenhouse Gas Protocol supplies the world's most widely used greenhouse gas accounting standards.
GHG Protocol standards provide a framework for businesses, governments, and other entities to measure and report their greenhouse gas emissions in ways that support their mission and goals. Their design is driven by generally accepted accounting and reporting principles (Completeness, Accuracy, Consistency, Relevance, and Transparency) and the needs of decision-makers.
In 2016, 92% of Fortune 500 companies responding to the CDP used GHG Protocol directly or indirectly through a program based on GHG Protocol. The popularity of GHG Protocol standards is due in part to the widespread stakeholder outreach and consultation that is facilitated by WRI and WBCSD during each standard development project.
