Climate negotiations under the UN framework are held through:

1. IMF
2. WHO
3. UNFCCC
4. FAO

The United Nations Framework Convention on Climate Change (UNFCCC) is the foundational treaty for international climate negotiations, adopted at the 1992 Earth Summit in Rio de Janeiro. With near-universal membership (198 parties), the UNFCCC convenes annual Conferences of Parties (COPs) to advance climate action, including landmark agreements like the 1997 Kyoto Protocol and 2015 Paris Agreement.
