For one week New York becomes the center of the climate universe — CEOs, ministers and activists all in town at once, with a public program reaching past conference rooms into art installations, screenings and neighborhood events. The open events are where the interesting collisions happen, often free and startlingly high-caliber. If you work anywhere near sustainability, browsing the event search and building a personal itinerary is the move.
What to expect
A sprawling decentralized program rather than one venue: expect panels and networking events in Midtown, exhibitions and activations scattered across the boroughs, and heavy security around UN-adjacent blocks. Flagship sessions are invite-heavy, but hundreds of affiliated events are open registration — the official event search is how you find them.
Good to know
- Most public events require free advance registration on the official site
- Flagship sessions like the Opening Ceremony are largely invite-only — target the open affiliate events
- Expect gridlock and security around Midtown East during UN week; use the subway
- Events span all five boroughs, not just Manhattan
- Great for professionals networking in sustainability, energy and policy
- Program listings update daily, so check the event search often
