Overview
- Brazilian President Luiz Inácio Lula da Silva opened the conference by condemning climate denial and floated a UN‑linked climate council to strengthen global governance.
- UN Secretary‑General António Guterres warned the 1.5°C target has been missed, calling the shortfall a moral failure and urging urgent course correction.
- Conference president André Corrêa do Lago urged a collective “mutirão” approach and set an implementation‑heavy agenda focused on faster emissions cuts, adaptation plans and finance.
- The United States did not send senior negotiators and is withdrawing from the Paris Agreement again, a step that small island states say undermines unity and shifts the talks’ gravity.
- Talks are centering on money and metrics, with developing nations pressing a roadmap toward roughly $1.3 trillion per year by 2035 and common adaptation indicators, as turnout exceeds 50,000 participants from about 170–200 countries.
