Brazil’s Cities Turn COP30 Climate Commitments Into Action Through Local Government Collaboration

Brazil is translating its climate ambitions into tangible urban improvements, as more than 100 cities and state governments work to advance sustainable transportation, waste management and climate-resilient infrastructure through a nationwide collaborative initiative.
Climate action is often measured by ambitious targets and international agreements. However, the more meaningful test is whether those commitments reach the communities expected to benefit from them. In Brazil, a growing network of municipalities is working to demonstrate what that transition can look like through coordinated investments, public policy and local government leadership.
Launched one year ago during the United Nations Climate Change Conference (COP30), the Brazil Mutirão Program is a partnership between C40 Cities and the Global Covenant of Mayors for Climate & Energy (GCoM), supported by Bloomberg Philanthropies. The initiative aims to accelerate climate solutions across Brazilian cities and states, connecting local governments with the technical expertise, financing and resources needed to turn environmental commitments into actionable projects.
The program has engaged more than 100 Brazilian cities and state governments, providing direct implementation support to more than 50. Among its most significant developments is the transition toward cleaner public transportation. More than $230 million has been mobilized through state and federal support to procure over 200 electric buses, with projects collectively encompassing nearly 600 vehicles. Recife, Belo Horizonte and Montes Claros are among the cities advancing fleet electrification.
Beyond transportation, organic waste management represents another significant opportunity for emissions reduction. Food scraps, garden trimmings and other organic materials account for approximately half of Brazil’s municipal solid waste. When deposited in landfills, decomposing organic matter generates methane, a greenhouse gas with substantially greater warming potential than carbon dioxide over a 20-year period. Through 17 projects developed by 21 subnational governments, approximately 30,000 metric tons of organic waste are expected to be processed annually. In Benevides, Pará, one initiative also connects waste management with environmental education across 41 municipal schools, potentially reaching more than 10,000 students.
The initiative is equally focused on how cities allocate public resources. Seven Brazilian cities are working to implement climate budgeting, a governance approach that integrates environmental commitments into municipal spending and policy decisions. Salvador established its Municipal Climate Governance Policy in September 2026, while Curitiba signed a climate budgeting decree in October. Campinas, meanwhile, plans to identify climate-related expenditures in its municipal budget beginning in 2028.
For Ana Toni, CEO of COP30, the objective extends beyond environmental targets. “Climate policy is not just about targets. It is about ensuring clean air, quality public transport, safe and resilient infrastructure, economic opportunities and a fairer future,” she said.
The program also supports climate planning across 11 Amazonian cities, helping municipalities identify vulnerabilities, assess environmental risks and prioritize investments. In Belém, which hosted COP30, the Belo Centro project is advancing sustainable urban mobility through the revitalization of its historic center.
Ultimately, Brazil’s approach reflects the meaning of mutirão: collective effort. By connecting municipal leadership with state and federal financing, international partnerships and community participation, the program demonstrates how climate commitments can move beyond conference halls and into everyday public life. Its lasting impact will depend not simply on the number of projects announced, but on the improvements residents experience in the cities they call home.
