Overview
- The gathering doubles as the decade mark of the Paris Agreement’s ambitions, with negotiations starting Monday, 10 November, in Belém, Brazil.
- UNEP underscores methane’s outsized short‑term impact and finds that a 45% cut this decade could avert roughly 0.3°C of warming by 2045, with emissions concentrated in agriculture (~40%), fossil fuels (~35%) and waste (~20%).
- The Global Methane Pledge targets at least a 30% reduction from 2020 levels by 2030, with measures spanning livestock and rice practices, leak detection in oil and gas, and improved waste management.
- The United States under President Trump will forgo high‑level attendance and is exiting the Paris accord again, while China signals ambitious goals and potential influence through its clean‑tech dominance.
- UNEP projects about 2.8°C of warming under current policies versus 2.3–2.5°C if commitments are fully implemented, steering expectations toward smaller, issue‑focused alliances such as methane deals and carbon market frameworks.
