This Protocol provides requirements and guidance for cities on preparing and publicly reporting a GHG emission inventory. The primary goal is to provide a standardized step-by-step approach to help cities quantify their GHG emissions in order to manage and reduce their GHG impacts.

The Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC) is a multi-stakeholder, consensus-based protocol for developing internationally recognized and accepted community-scale greenhouse gas accounting and reporting standards.

This Annual Report of the carbonn Cities Climate Registry (cCCR) presented to the 17th Conference of the Parties to the UNFCCC, the UN Climate Secretariat and the global climate community assembled in Durban, reflects the determination of cities worldwide to pursue their climate policies and actions with transparency and accountability.
