The World Resources Institute’s Sustainability Initiative seeks to align the Institute’s business practices with its mission. Walking the talk on sustainability, a new report discloses our 2012 GHG inventory results and discusses GHG reduction projects and other sustainability projects completed in the last year.
Low-carbon development has become the core theme of China’s urbanization. In fact, it’s one of the country’s key strategies to achieve its target of reducing carbon intensity by 40-45 percent by 2020.
China’s National Development and Reform Commission (NDRC) has identified 36 pilot cities and assigned them several tasks.
A number of programs that require businesses to report their greenhouse gas (GHG) emissions have emerged in the past decade at the regional, national, and sub-national levels. Most of these programs operate in developed countries, but some developing countries are also showing an interest in adopting mandatory emissions disclosure programs.
Establishing these programs is a resource- and time-intensive exercise. It can be a daunting task for developing countries with competing priorities and limited resources. So where can these countries begin as they consider setting up their greenhouse gas reporting schemes?
WRI’s new working paper, Designing Greenhouse Gas Reporting Systems: Learning from Existing Programs, reviews corporate and facility-level greenhouse gas reporting programs in Australia, California, Canada, the European Union, France, Japan, the United Kingdom, and the United States. The paper identifies steps to implement a mandatory reporting program and discusses factors to be considered at each step in designing the program.
It also discusses some strategies for developing countries keen to set up reporting programs. Developing countries may find it easier to adopt a gradual, phased approach to develop a reporting program. Engaging in the following three key steps allows developing nations to make the most of their more limited resources:
Rio de Janeiro is a leader among the Brazilian cities aggressively promoting low-carbon development. In 2011, the city passed a landmark climate change law with a target to reduce greenhouse gas (GHG) emissions 8% below the business-as-usual (BAU) emissions scenario by 2012, 16% by 2016, and 20% by 2020.
Now Rio is conducting a GHG inventory for 2012, the first target year under its climate change law. The inventory will measure the city’s emissions against its 8% reduction target for 2012, and assess the effectiveness of GHG mitigation actions implemented so far. On July 2, the city government of Rio invited me and my colleagues from the Greater London Authority and the Federal University of Rio de Janeiro (COPPE) to a seminar to share our experiences in conducting GHG inventories and to discuss Rio’s 2012 inventory. At the seminar, Nelson Moreira Franco, Director for Climate Change Management and Sustainable Development for the City of Rio, stressed that GHG inventories help identify emission sources and provide scientific evidence on GHG levels, so it is extremely important that the city gets it right. To me, the seminar covered four important items:
Wading through the vast sea of global greenhouse gas (GHG) emissions data can be a real challenge. To help simplify the process and make such data more accessible, today the World Resources Institute is launching the Climate Analysis Indicators Tool, or CAIT 2.0.
The free, online portal provides data on GHG emissions from 186 countries and all 50 U.S. states, as well as other climate data. CAIT 2.0 allows users to view, sort, visualize, and download data sets for comparative analysis. By providing comprehensive emissions data in an easy-to-use tool, users from government, business, academia, the media, and civil society can more effectively explore, understand, and communicate climate change issues.
Check out a screencast of how CAIT 2.0 works.
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.
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.”
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.

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:
