For the First Time, a Common Framework for Cities’ Greenhouse Gas Inventories

UPDATE: The deadline to apply to pilot test the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC) has been extended to March 31, 2013. Download the Terms of Reference and Application Form for the pilot project, as well as other relevant documents about the GPC.

“You cannot manage what you cannot measure” is a well-known adage for business, and the phrase is increasingly relevant for cities. In the past decade, many cities have started measuring their greenhouse gas (GHG) emissions data. GHG inventories are essential for building effective low-carbon strategies, tracking GHG reductions, responding to regulations and local GHG program requirements, and securing climate finance. Some cities also believe that tracking emissions can eventually conserve financial and other resources.

The challenge is that most cities conduct their inventories using different methodologies. Without an internationally consistent framework for GHG accounting and reporting, inventory results can be confusing and misleading to decision-makers, investors, and civil society stakeholders. This lack of consistency can even jeopardize the accountability and effectiveness of cities’ emission-reduction efforts.

The Global Protocol for Community-Scale GHG Emissions

But there is a solution: WRI partnered with C40 Cities Climate Leadership Group (C40) and ICLEI – Local Governments for Sustainability (ICLEI) to develop the Global Protocol for Community-Scale GHG Emissions (GPC) Pilot Version 1.0. This guide—which is now beginning its pilot-testing phase—is set to become the first internationally accepted framework for city-level GHG inventories.

As the GPC begins its pilot-testing phase, city leaders may wonder about the specific benefits of using a standardized GHG accounting method. Let’s take a look at GHG reporting trends in cities and the risks of using inconsistent methods.

CAIT’s Global Greenhouse Gas Emissions Data Now Available in Google Public Data Explorer

Last year, in an effort to make our climate data more accessible, WRI launched a pilot that paired estimates of U.S. state greenhouse gas (GHG) emissions from our Climate Analysis Indicators Tool (CAIT) with the Google Public Data Explorer, a tool that visualizes large data sets with interactive charts and maps.
