Climate Week NYC is the world’s leading climate event, organized by  Climate Group, an international nonprofit that has driven climate action for over two decades. Every year, in coordination with the UN General Assembly, we bring together the decision makers shaping capital, policy and markets to speed up progress. The solutions exist. The challenge now is delivering them at speed and scale.

In 2026, more than 120,000 participants joined 1,500+ events across New York City with one clear message: the economic case for climate action has been made, and the focus now is on delivery.
