Climate Week NYC 2026 has come to a close. More than 1,500 events, tens of thousands of attendees, and eight days of conversations across every corner of the city, alongside two days of flagship sessions.
One message ran through all of it: commitments must now become delivery. The decisions taken on energy, investment, infrastructure and policy in the months ahead are what turn this week's conversations into progress at scale.
Helen Clarkson OBE, CEO, Climate Group, closes the week with a reflection on the optimism these conversations generated, and on what needs to happen next.
"We must turn this economic argument into political courage."
Thank you to everyone who joined us, in the room, across the city and online.
Sessions from The Opening Ceremony and The Hub Live are available to watch on demand.

Climate Week doesn't end with a closing ceremony. It ends with people signing up for the next thing. Two events tonight take the week's conclusions and ask what happens on Monday: a coalition launching with the specific request that everyone present take one concrete step before they leave, and a panel on how the economics that drive extraction also drive the exploitation of the people doing the extracting. Join either, and finish the week having committed to something.
12.00pm ET
The week closes with a run of events that make their argument through something other than a slide deck. Paint mixed from beetroot peel and coffee grounds. A comedy show set in a community board meeting about flooding, developed with NYC Emergency Management. A woven sculpture built around the birds that die on the city's glass buildings. And in Newtown Creek, a choose-your-own-adventure evening with a Butoh puppetry performance, a choir that learns a Joni Mitchell arrangement in a single day, and a rooftop party to finish. Join any of the following, and bring someone who wouldn't sit through a panel.
11.50am ET
Mete Coban MBE, Deputy Mayor of London for Environment and Energy, Greater London Authority, was in New York this week and shared a clip from his visit. His message was about what London and New York have in common: two city administrations using progressive leadership to deliver for working class communities, and a week spent sharing ideas and building the partnerships that make a fairer London possible.
Great to have him on stage on Tuesday for The AI Forum: Scaling sustainable infrastructure, where the conversation turned to what it takes to build data center capacity that works for the communities hosting it.
10.05am ET
The Global Citizen Festival, held on Central Park's Great Lawn each year during the same week as Climate Week NYC, was cancelled this weekend because of severe weather. European Commission President Ursula von der Leyen had been due to address the crowd. Her message and her commitment went ahead regardless, shared by Global Citizen afterwards.
"When a crisis strikes, we step up and take action. That is what it means to be a Global Citizen."
On behalf of Europe, she pledged more than $800 million to support people in need around the world, covering food, safety, shelter and healthcare for displaced communities, and emergency aid for those hit by war, disease and natural disaster. Global Citizen said the announcement brings the total in commitments from $208.8 million to $1.01 billion.

The Rockaways get the whole day.
Out on the peninsula, a cluster of organizations have built something more ambitious than a single event. Dune Dreams and Peninsula Power runs from ten this morning across several locations around the bay, and it starts where most climate programming doesn't: with how people actually feel about it. A discussion on climate emotions, then a walking tour and scavenger hunt carrying audio recordings from stewards and community members, with artistic interventions along the route. A bird walk runs alongside it.
It's put together by Holes in the Wall Collective, RISE Rockaway, Climate Cafe NYC, the Climate Imaginarium, the Garden by the Bay and the NYC Plover Project, on a stretch of coast that has spent the week being discussed in Manhattan conference rooms as a case study in resilience.
08.00am ET
Birds, wildlife and the city they share - It's peak fall migration, which makes the last Sunday of Climate Week an unusually good day to look up. Birds are moving through the city in numbers right now, and several of today's events are built around that: shorebirds and raptors along Rockaway Beach, warblers stopping to refuel on Governors Island, and a slower version in Central Park that starts with journaling and a meditation before anyone lifts a pair of binoculars. There's something for families too. Join any of the following.
06.25am ET
The week ends in motion. Two runs set off before most of the city is awake, one through the New York Botanical Garden and one over the Palisades, both raising money for the land they're run on. Later there's a free ride through Central Park, a thrift crawl across Ridgewood, a tour of what East Village gardens have worked out about energy, and a workshop that sends you home able to fix your own bike. Join any of the following.
06.00am ET
The last day. After a week of plenaries, podiums and policy, Climate Week NYC finishes the way it probably should: outdoors, on foot, and mostly free. Two races before nine, bird walks in three boroughs, paint made from beetroot, a comedy show about flooding, and a coalition launch in the late afternoon.
