The General Reporting Protocol (GRP) represents the platinum standard in greenhouse gas (GHG) emissions accounting practices and provides rigorous, consistent and transparent standards for the calculation of comprehensive and accurate GHG emissions inventories.

The GRP covers the policies of The Registry, guides Members in determining what to report, provides quantification guidance and calculation methodologies for emissions sources, and describes the process for publicly reporting emissions through CRIS.

The GRP was developed through a public consensus-based stakeholder process and is consistent with international standards such as the International Organization for Standardization (ISO) and WRI/WBCSD.
