Rio Climate Action Week

Rio Climate Action Week (RCAW) is an independent initiative, in partnership with the Mayor of Rio de Janeiro and London Climate Action Week. It is the latest edition of a series of city-based climate action weeks – which include Auckland, Baku, Bangkok, Dublin, Prague, Shanghai and Sydney – inspired by the unique model pioneered by London Climate Action Week from 2019 onwards.

RCAW is closely tied to the UNFCCC process of climate diplomacy and its implementation-focused action agenda. It owes its origins to a desire to promote closer cooperation between the COP29 and COP30 Presidencies at a pivotal time for international climate change policy and action.

Rio Climate Action Week is a prominent city-based response to the Brazilian COP30 Presidency’s call for “mutirão” – collective effort.

RCAW and the climate action weeks are Mutirão in Action: demonstrating both bottom-up and top-down action to mitigate and adapt to the impacts of climate change and build resilience across societies and communities.
