Climate Week NYC 2026 took place September 20–27, 2026.
The event was billed as bringing together more than 100,000 people across more than 1,000 events held throughout New York City during the week.
Climate Week NYC took place across New York City; it did not have a single venue, as it spanned more than 1,000 independently hosted events city-wide.
Attendees included global leaders shaping markets and policy, decision-makers and experts across sectors and regions, and businesses, governments, communities and individuals participating through the official Events Program.
It suits sustainability executives, investors and policy staff who want many meetings in one week, since it ran alongside the UN General Assembly and spread more than 1,000 events across New York City. Attendees wanting one focused, single-room program get less from it, because the week was a city-wide set of separate events and a schedule had to be assembled from the official Events Program.
