Ambassador André Corrêa do Lago’s second COP30 letter published on 8 May 2025, sets out a vision for global climate action under the concept of a “Global Mutirão”, a Tupi-derived Brazilian term meaning ‘collective effort’.It introduces four Circles of Leadership to advance collaboration and proposes self-determined contributions (SDCs) as a grassroots complement to Nationally Determined Contributions (NDCs). These contributions from individuals, communities, and organisations are geared at shifting responses to a whole of society one. The four circles of leadership are to include a Circle of Peoples to amplify the voices of indigenous, youth, and marginalised communities; a Circle of Finance Ministers to mobilise climate finance through financial leadership; and a Global Ethical Stocktake Circle to reflect on the moral dimensions of climate action as well as a COP Presidents’ Circle, led by Laurent Fabius from COP21 and other former COP leaders.
