UN General Assembly adopts resolution on state climate obligations after Vanuatu initiative

On 20 May 2026 the United Nations General Assembly in New York voted 141‑8‑28 to adopt a resolution that formally acknowledges the climate obligations of all states, echoing the advisory opinion of the International Court of Justice issued in July 2025. The motion, first proposed by the Pacific island nation of Vanuatu, calls on governments to honour existing climate‑related duties under customary international law and to consider a mechanism for recording loss and damage caused by climate change.

The vote saw opposition from the United States, Israel, Iran, Russia, Saudi Arabia, Liberia, Yemen and Belarus, while Italy broke with earlier diplomatic ambiguity and supported the text. Though the resolution does not create new binding legal duties, it recognises the ICJ’s authority, encourages compliance with the 1.5 °C target, and leaves open the possibility of an international loss‑and‑damage register that could underpin future compensation claims.
