Climate Week NYC

Climate Week NYC returns: September 20–27, 2026

This year's Climate Week NYC will focus on the energy, the impact, and the action that we drive together.

In times of economic and climate uncertainty, collaboration, and learning from one another is key. There’s so much to talk about, so many issues that are driving decision making in boardrooms and in departments.

It’s exactly why Climate Week NYC was set up, and why it returns from September 20–27, 2026. Climate Week NYC is the world’s largest climate event, bringing together more than 100,000 people across 1,000+ events in New York City.

From global leaders shaping markets and policy, to communities driving change on the ground, it connects the people and ideas transforming how we live, work and build a low-carbon economy and a more secure future.

Whether you’re in New York City or joining from around the world, Climate Week NYC connects you to the ideas, decisions and partnerships shaping the global transition.

Climate Week NYC is organized by Climate Group, an international organization that has driven climate action for over 20 years by convening leaders across business and government. Taking place alongside the UN General Assembly, our event brings together the decision-makers and experts shaping capital, policy and markets across sectors and regions.
