City GHG Accounting

Cities have become widely recognized as major contributors to global greenhouse gas (GHG) emissions. Fifty-four percent of the world’s population, approximately 3.9 billion people, reside in urban areas. The 2008 World Energy Outlook estimated that cities accounted for over 70% of global carbon dioxide emissions from energy consumptions. To address growing urban GHG emissions it is necessary to understand each city’s emission patterns and identify the major sources of emissions as well as reduction opportunities from both direct and indirect sources.

Global Protocol for Community Scale Emissions (GPC)

WRI, ICLEI – Local Governments for Sustainability (ICLEI) and C40 Cities Climate Leadership Group (C40) are jointly developing the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC). The GPC serves as the global standard for accounting and reporting city and community-scale GHG emissions that covers scope 1, scope 2, and some scope 3 emission sources. In May 2012, the partners released the GPC Pilot Version 1.0, which was pilot tested in 35 cities around the world. The release of the final version is expected in late 2014.

In a future stage of development, we will expand the GPC to include a full value chain assessment of GHG emissions (release planned for 2015). It will provide detailed scope 3 guidance, which will help cities and communities measure their GHG emissions across a full range of direct and indirect emission sources. This comprehensive look at local-level emissions will help cities and communities ensure that all emissions are being accounted for between different government municipalities.

Pilot Cities

From May to December 2013, 35 cities around the world pilot tested the GPC Pilot Version 1.0. The terms of reference for the pilot project can be found here. Below are the past and upcoming stakeholder consultation events.

Calculation Tools

In the standard development process, we are also developing calculation tools to apply the GPC.

Tools Developed by GHG Protocol

GHG Accounting Tool for Chinese Cities
This GHG accounting tool is developed specifically for Chinese cities based on the GPC framework. It provides local emission factors and the design of data input templates are suitable for Chinese statistical data. It is developed in partnership with the Institute for Urban and Environmental Studies, Chinese Academy of Social Science (CASS), WWF China and ISC.

To Be Updated

Practical Application

In parallel with the development of the GPC and its associated calculation tools, we work with cities and sub-national regions to apply the standard and develop practical solutions toward low-carbon development. Some of our partner cities and regions include:

  • Rio de Janeiro, Brazil
  • Sao Paulo, Brazil
  • Bangalore, India
  • Guangdong, China
