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.”
