The world is still far off track to reduce emissions in line with the Paris Agreement, while extreme weather events fuelled by man-made climate change, including hurricanes, heatwaves, floods and wildfires, are having devastating impacts on communities across the world.
At the 30th United Nations Climate Change Conference of the Parties (COP30), which takes place in Belém, Brazil from 10 - 21 November 2025, countries must come together to take strong collective climate action. The 2025 UNEP Emission Gap Report, which included a contribution from Professor Joeri Rogelj, found that we are still on track for 2.3-2.5°C if countries fully implement their Nationally Determined Contributions.
Host nation Brazil has set out three priorities for the negotiations:
- Reinforce multilateralism and cooperation
- Connect climate change to individuals and the economy
- Accelerate implementation
