Brazil has been selected for the Brazil Mutirão Programme, which is being carried out by C40 Cities and Global Covenant of Mayors for Climate & Energy (GCoM). The project will provide technical and financial assistance to climate initiatives in 34 cities and two states in Brazil.

In the first stage of the program, there will be projects in the areas of urban mobility, waste management, and climate budgeting. There are 11 selected cities located in the Amazon region. Also, six cities – Barcarena, Altamira, Cáceres, Boa Vista, Parintins, and Rio Branco will get assistance in preparing climate action plans.

The project was officially launched at the General Assembly of the National Front of Mayors in Curitiba. Some of the participating cities are Curitiba, Rio de Janeiro, São Paulo, Salvador, Fortaleza, Belo Horizonte, and Belém. Also, Pernambuco and Rio Grande do Sul are participating states.

The planned transport projects include 600 electric buses, more than 200 km of cycling infrastructure, nine complete streets/urban parks, and the renovation of at least three neighborhoods.

Waste management projects involve the processing of approximately 20,000 tonnes of organic waste per annum. The programme's calculations estimate that it may reduce emissions by up to 35,000 tonnes of CO2e and methane emissions per year.

As quoted by Michael R. Bloomberg, United Nations Special Envoy for Climate Ambition and Solutions and founder of Bloomberg Philanthropies, the programme offers technical assistance, information, and coordination to support the development of climate projects by local governments.

Mark Watts, C40 Cities' executive director, stated that the programme unites the technical assistance and partnerships to support projects in transport, waste management, and urban planning sectors.

Brazil Mutirão Program is included in the Coalition for High Ambition Multilevel Partnerships (CHAMP), which was announced at COP28 in order to improve collaboration between national governments and local authorities on climate actions.

As quoted by the organizers of the project, participating cities and states will use this programme to develop projects for funding and implementation next year.
