The Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC) is a joint project by ICLEI-Local Governments for Sustainability (ICLEI), the World Resources Institute (WRI) and C40 Cities Climate Leadership Group (C40), with additional collaboration by the World Bank, UNEP, and UN-Habitat. As a global reporting standard, the GPC enables cities and communities to consistently measure and report GHG emissions and develop climate action plans and low-emission urban development strategies.
The GPC provides the most comprehensive greenhouse gas (GHG) accounting and reporting framework for cities around the globe. It allows local governments using this consistent standard to:

The Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC) is the result of a collaborative effort between the GHG Protocol at WRI, C40, and ICLEI. The development of the GPC began in June 2011 as a result of a Memorandum of Understanding between C40 and ICLEI. In 2012, the partnership expanded to include WRI and the Joint Work Program of the Cities Alliance between the World Bank, UNEP, and UN-HABITAT.
An early draft was released in March 2012 for public comment. It was then updated (“GPC Pilot Version 1.0”) and tested in 35 cities worldwide. During the same period, six in-person stakeholder consultation workshops were organized in Beijing, Sao Paulo, London, Dar es Salaam, New Delhi, and Jakarta Over 150 city officials, researchers, and practitioners from around the world provided feedback to the GPC Pilot Version 1.0. Based on this feedback, the GPC was further revised and issued for a second public comment in July-August 2014. The final version of the GPC was published in December 2014. It supersedes all the previous draft and pilot versions.
Throughout the piloting process cities provided valuable input and contributed to making the GPC more user-friendly and technically robust. The GPC contains several improvements from its pilot version, including:
The GPC and the Compact of Mayors
The GPC also underpins the global Compact of Mayors, the world’s largest cooperative effort among cities to reduce GHG emissions, track progress and prepare for the impacts of climate change. The Compact – endorsed by preeminent global city networks – has adopted the GPC as part of its core activities to raise the level of ambition and quality of city GHG inventory reporting. Using GPC, cities can report emissions through the carbonn Climate Registry, the Compact’s designated central repository.
An earlier version from 2012, the GPC marks an unprecedented international consensus on GHG accounting and reporting emissions. It also aids the growing number of cities voluntarily reporting to the carbonn Climate Registry (cCR). The cCR is the world’s largest reporting platform on climate actions and commitments and the designated repository for the Compact of Mayors, launched in September 2014. The GPC equips reporting cities to consistently measure and track their actions and make a credible case for accessing local and international climate financing.
The Harmonized Emissions Analysis Tool plus (HEAT+) is a GPC compatible multilingual online emissions inventory tool to help Local Governments account GHGs, Common Air Pollutants (CAP) and other Volatile Organic Compounds (VOC). HEAT+ helps Local Governments make informed climate action decisions and identify the most effective measures in emissions and pollutant abatement.
