33 Cities Test New Framework for Community-Scale Greenhouse Gas Inventories

A growing number of countries and companies now measure and manage their emissions through greenhouse gas (GHG) inventories. Cities, however, lack a common framework for tracking their own emissions—until now.

Thirty-three cities and communities from around the world started pilot testing the Global Protocol for Community-Scale Greenhouse Gas Emissions Pilot Version 1.0 (GPC Pilot Version 1.0) last month. The GPC represents the first international framework for greenhouse gas accounting for cities. It was launched in May 2012 as a joint initiative among WRI, C40, and ICLEI in collaboration with the World Bank, UN-HABITAT, and UNEP.

Hundreds of companies and organizations around the world are using GHG Protocol standards and tools to manage their GHG emissions and become more efficient, resilient, and prosperous organizations.

Through the Greenhouse Gas Protocol (GHGP) World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) work with businesses to develop standards and tools that help companies measure, manage, report and reduce their carbon emissions.

6 Lessons Brazilian Cities Learned from Greenhouse Gas Inventories

This piece provides insights from a recent Greenhouse Gas Protocol seminar in Brazil. The Seminar was part of WRI’s Sustainable Cities Initiative funded by the Caterpillar Foundation.

Last week in São Paulo, WRI, ICLEI, C40, USP-IEE, and EMBARQ Brazil jointly brought together more than 200 Brazilian city officials and experts to discuss how to use the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC) to measure and manage greenhouse gas (GHG) emissions from cities. Representatives from Brazil’s federal and state governments, as well as city-level governments including São Paulo, Rio de Janeiro, Belo Horizonte, and Piracicaba, shared their experiences in conducting GHG inventories and implementing local climate actions.

Brazilian cities and municipalities vary in the status of their efforts to collect GHG data and conduct emissions inventories. The event focused on emissions management efforts so far. Below are six lessons highlighted by participants in the discussion:

1. Strong political commitment is crucial for success. Many cities in Brazil have made strong political commitments to address climate change. For example, Rio and Belo Horizonte have created municipal climate change laws with mandatory GHG reduction targets. Rio’s target is to reduce emissions by 20 percent below 2005 levels by 2020, while Belo Horizonte’s is 20 percent by 2030. In both cases, city-wide GHG inventories have been conducted to inform and track performance toward these targets.

2. The inventory is the first step in low-carbon development. Participants stressed the importance of the GHG inventory process (see figure below) as a planning tool to help cities assess their emissions, identify emission sources, set reduction targets, prioritize mitigation actions, and track performance. For instance, Belo Horizonte’s inventory found that the transportation sector is the city’s major source of GHG emissions (71 percent); this information will help the city identify reduction measures. Prof. Jose Goldemberg, former federal Minister and São Paulo State Secretary of Environment, stressed that GHG inventories help cities identify key emission sources and implement low-carbon technologies. Nelson Moreira Franco, Director for Climate Change Management and Sustainable Development for the City of Rio, stressed that the “GHG inventory is a powerful instrument to manage emissions and influence policy-making.”

Nitrogen Trifluoride Now Required in GHG Protocol Greenhouse Gas Emissions Inventories

Scientific understanding of the chemicals that contribute to climate change is constantly improving. So, too, is the Greenhouse Gas Protocol (GHGP), as we work to keep abreast of such advances and ensure that they are reflected in our tools and standards.

One recent example concerns the greenhouse gas (GHG) nitrogen trifluoride (NF3), a chemical that is released in some high-tech industries, including in the manufacture of many electronics. The GHG Protocol now requires NF3 to be included in GHG inventories under the Corporate Standard, Value Chain (Scope 3) Standard, and Product Standard. A new GHGP Amendment updates the existing requirements.

How does this update affect my organization?

NF3 is used in a relatively small number of industrial processes. It is primarily produced in the manufacture of semiconductors and LCD (Liquid Crystal Display) panels, and certain types of solar panels and chemical lasers. To the extent that these processes occur in your company’s direct operations or value chain, they may need to be reflected in future inventories to ensure conformance with GHG Protocol standards.

Lessons Learned from Low-Carbon City Planning in Malaysia

Stacy Kotorac, a project coordinator/research assistant with the Greenhouse Gas Protocol, also contributed to this blog post.

Low-carbon city development has become a central part of the Malaysian government’s strategy to meet its greenhouse gas (GHG) commitments. The country, currently ranked second in terms of emissions per capita in Southeast Asia, has committed to reduce the emissions intensity of its gross domestic product (GDP) by 40 percent from 2005 levels by 2020.

Many Malaysian cities have created ambitious, low-carbon visions in order to meet national targets. However, many cities don’t yet have a credible GHG inventory or a comprehensive blueprint to help them systematically implement and monitor low-carbon actions. Without such a framework, it is nearly impossible to establish baseline measurements, set goals, or measure progress.

That’s why the GHG Protocol is currently working with partners to develop a standard methodology, the Global Protocol for Community Scale Emissions (GPC), as well as an accompanying toolkit that cities will be able to utilize to plan for their low-carbon development. Last year, we released the GPC Pilot Version 1.0. Over the next six months, about 30 cities will pilot test it.

Tracking Greenhouse Gases: 3 Factors for Successful National Inventories

This blog post was co-authored with Soffia Alarcon-Diaz, an intern with WRI's Climate and Energy program.

Measuring and reporting greenhouse gas emissions (GHGs) across different sectors is no easy feat. But creating a national inventory of GHGs is one important step for countries to take toward managing them. Starting in 2014, many developing countries will begin providing more frequent updates to their national inventories under guidelines from the COP 17 Durban Platform. How can they best meet international reporting requirements and, more importantly, use the development of their national inventory systems to support domestic low-carbon growth?

In a new set of case studies (see the text box) we have documented experiences from Brazil, Colombia, India, Mexico, and South Africa—countries that have already made notable efforts to develop robust national inventory systems. Each study explores critical aspects of these countries’ inventory processes and provides lessons that could benefit other countries looking to further develop their own systems.

3 Attributes of Successful National Greenhouse Gas Inventories

Although each national inventory system is unique, the case studies reveal several common attributes of successful inventory improvement. Here are three:
