Climate Week NYC is the largest annual climate event of its kind, bringing together over 900 events and activities across the City of New York – in person, hybrid and online. Each year, business leaders, political change makers, local decision takers and civil society representatives of all ages and backgrounds, from all over the world, gather to drive the transition, speed up progress, and champion change that is already happening. 

Climate Week NYC 2025 returns to the City of New York from September 21-28. We’ll bring together inspiring heads of government and leaders from the world of business, tech, academia, and civil society to discuss the challenges and opportunities we face.

There’s never been a more important time to Power On. Together, we can unlock barriers, build alliances, and seize opportunities to stay competitive in a changing world.

The Opening Ceremony will take place on Monday, September 22, with a thought-provoking agenda [1] and sessions taking place at The Hub Live, as well as our inspiring line-up of confirmed speakers. 

Registration for in-person attendance is open. For those unable to attend in-person, we'll stream key sessions from the week available through our on demand page. Wholly digital events are also included in Climate Week NYC’s Events program.
