Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC)

Responsible for more than 70 percent of global energy-related carbon dioxide emissions, cities represent the single greatest opportunity for tackling climate change. The first step for cities to realize their potential is to identify and measure where their emissions come from -- you can’t cut what you don’t count.

The GPC provides a robust framework for accounting and reporting city-wide greenhouse gas emissions. It seeks to:

- Help cities develop a comprehensive and robust greenhouse gas inventory in order to support climate action planning
- Help cities establish a base year emissions inventory, set reduction targets, and track their performance
- Ensure consistent and transparent measurement and reporting of greenhouse gas emissions between cities, following internationally recognized greenhouse gas accounting and reporting principles
- Enable city inventories to be aggregated at subnational and national levels
- Demonstrate the important role that cities play in tackling climate change, and facilitate insight through benchmarking – and aggregation – of comparable data

The GPC is the newest and full publication that has taken into consideration feedback from the pilot test in 2013 and global public comments in 2012 and 2014. It replaces all the previous draft versions of the GPC and supersedes the International Local Government Greenhouse Gas Emissions Analysis Protocol (community section) published by ICLEI in 2009 and the International Standard for Determining Greenhouse Gas Emissions for Cities that published by the World Bank, United Nations Environment Programme (UNEP), and UN-HABITAT in 2010.

To date, more than 100 cities across the globe have used the GPC to measure their greenhouse gas emissions.
