Driving the Nature-Positive Transition
The 5th edition of the World Climate & Biodiversity Summit took place in New York on 25 September 2025, held on the sidelines of Climate Week NYC and the 80th Session of the UN General Assembly.
Recognizing that climate change and biodiversity loss are deeply connected and demand a unified response, the 2025 event merged the World Climate Summit and the World Biodiversity Summit into a single platform for action.
Grounded in the principles of the Rio Conventions – UNFCCC, UNCBD, and UNCCD – the Summit brought together leaders from business, government, finance, academia, and civil society. The goal was to advance holistic solutions that address both climate and nature, as well as to support the implementation of the Kunming-Montreal Global Biodiversity Framework and the Paris Agreement.
