Projects will provide green transport, cut greenhouse gas emissions and introduce nature-based solutions to strengthen climate resilience in four major cities.
Four new cities have been chosen to receive funding support from the C40 Cities Finance Facility (CFF) to turn their climate plans into tangible, finance-ready infrastructure projects.
Projects will provide green transport, cut greenhouse gas emissions and introduce nature-based solutions to strengthen climate resilience in the four major cities.
Implemented jointly by Deutsche Gesellschaft für Internationale Zusammenarbeit (Giz) and C40 since 2015, the CFF is a project preparation facility helping cities develop inclusive urban infrastructure projects and link them to climate finance.
The first group of new partner cities for CFF’s fourth phase was announced at the 2025 C40 World Mayors Summit in Rio de Janeiro as:
Resilient urban watersheds in Belo Horizonte, Brazil
Nature-based urban regeneration in São Paulo, Brazil
Solar-powered e-buses in Rabat, Morocco
Clean ferries in Cartagena, Colombia
With the support of Germany’s Federal Ministry for Economic Cooperation and Development (BMZ) and the UK’s Foreign, Commonwealth and Development Office (FCDO), CFF will collaborate with these cities to prepare and implement these projects to improve the lives of residents with large-scale, measurable impact.
“It is not merely about renewing our bus fleet, but rather a foundational investment designed to enhance the quality of life for all citizens across Greater Rabat”
Launched in 2015 at Cop21 in Paris by Rio mayor Eduardo Paes, CFF has become a leading project preparation facility partnering with cities in the Global South to enable transformative climate action. By putting cities’ best interests first, CFF is helping cities prepare and implement urban infrastructure projects that address the impacts and injustices of climate breakdown and that make a real difference to people’s lives.
“For the first time in Colombia, our residents will have an aquatic service designed for them – one that will make it easier to reach jobs, healthcare, and education,” said Dumek Turbay, mayor of Cartagena.
"We dreamed it together, we heard it from our communities, and today we make it a reality: a sustainable transport system that unites, connects, and improves the lives of all Cartageneros.”

Fatiha el Moudni, mayor of Rabat, said: “This pivotal project is a key step in implementing our strategic vision for sustainable urban mobility. It is not merely about renewing our bus fleet, but rather a foundational investment designed to enhance the quality of life for all citizens across Greater Rabat.”
Co-director of the C40 Cities Finance Facility, Ingrid Simon, said: “The C40 Cities Finance Facility is delighted to announce its four new partner cities – Belo Horizonte, Cartagena, São Paulo and Rabat – whose fantastic projects will build communities’ resilience to extreme heat and flooding, connect people to employment and services, and create cleaner, healthier environments.
“Thanks to the support of the German and British governments, we’re proud to continue to assist cities in developing real projects that make a real difference to people’s lives.”
