Below are remarks from UN Climate Change Executive Secretary Simon Stiell, during the closing plenaries of COP30 in Belém, Brazil, on Saturday 22 November 2025.

Excellencies, Colleagues,

Dear Friends,

We knew this COP would take place in stormy political waters.

Denial, division and geopolitics has dealt international cooperation some heavy blows this year.

But friends. COP30 showed that climate cooperation is alive and kicking, keeping humanity in the fight for a livable planet, with a firm resolve to keep 1.5C within reach.
