Second letter from the COP30 Presidency moves from vision to action with details on the call for a “global mutirão” against climate change
The document presents a proposal for mobilization and calls for new models of governance to deal with the climate crisis and the complexities of the 21st century.

On Thursday (8 May), the President of COP30, Ambassador André Corrêa do Lago, released a new letter outlining the call for an unprecedented mobilization against climate change, in a global collective effort known as “multirão” to promote greater climate action and ambition. The document also introduces the Leadership Circles and the four pillars of the conference, which Brasil will host in Belém, Pará, from November 10 to 21.
Following the first letter published in March, which set out the vision for COP30, the new publication presents the four pillars of the conference: Mobilization, Action Agenda, Negotiations and Leaders' Summit. In this letter, the COP30 President elaborates on the mobilization pillar and announces that the other pillars will be detailed in forthcoming statements.
One of the goals of the “mutirão”, according to Corrêa do Lago, is to create a global movement that integrates local actions. The letter invites sub-national governments, the private and financial sectors, civil society, social movements and individuals, among others, to work together to build this process.
The “mutirão” is a tangible action that is already being implemented on the ground: farmers adopting local regenerative practices; young people installing solar panels in vulnerable communities; coastal cities organizing brigades to restore mangroves; technology companies joining forces to decarbonize data centers; Afro-descendant communities creating urban climate education programs, among others. The common message is one of collective, immediate and autonomous contribution to a sustainable future.
To contribute to this ongoing transformation, the presidency highlighted the creation of four Leadership Circles, launched in April: COP Presidents' Circle, Peoples' Circle, Finance Ministers' Circle, and Global Ethical Stocktake (GES). The circles will act independently alongside the negotiations, working to assist the COP30 Presidency.
The text comes at a critical time: the latest report from the World Meteorological Organization confirms that 2024 will be the hottest year on record. Given this scenario, Corrêa do Lago says COP30 should mark a turning point in the fight against climate change, moving from vision to action with a "chain of action" for low-carbon solutions and climate resilience on an exponential scale.
Inspired by the encyclical Laudato Si' and the legacy of Pope Francis, the presidency also seeks to broaden global awareness through inclusive dialogues between political, academic, cultural, religious, and community leaders. These spaces must recognize and empower the contributions of indigenous peoples, traditional communities, Afro-descendant groups, youth, women, among others, whose critical perspectives are essential for a more just and effective local and international solutions.
In times of exponential change, the letter also calls for new international cooperation infrastructures capable of aligning efforts, sharing intelligence, and combining new technologies with traditional knowledge. Examples include tropical forests and the Internet: complex, diverse, and complex systems that inspire innovative solutions for a century of complexity.
