Climate Week NYC 2026

Climate Week NYC is the largest annual climate event, run by the Climate Group alongside the UN General Assembly, taking place across New York City on 20–27 September 2026. It is expected to span more than 1,000 affiliated events and draw over 100,000 people, connecting global leaders shaping markets and policy with community organisers driving change on the ground. The official programme covers energy, food, policy, environmental justice, health and resilience, anchored by the Opening Ceremony, The Hub Live, The Executive Series and the Climate Leaders' Reception, with the bulk of the week made up of independently hosted events registered through the official programme. For business and government, it functions as a focal point for energy and climate action and the move to a low-carbon economy.
