Climate Week NYC 2026 was our biggest yet, bringing together more than 120,000 attendees across over 1,500 events throughout the city. From maritime history and ocean conservation to clean energy and sustainable supply chains, the program brought climate action into new spaces and conversations.
Here are six events that show the breadth of ideas and solutions shared throughout the week.
Hosted by Christa Avampato, NYC's Secrets and Lies
A guided walking tour through the South Street Seaport Historic District explored how climate, commerce, and history have shaped what New Yorkers eat. Starting at Tall Ship Wavertree, participants traced a route once paved with oyster shells that now helps defend against rising tides, uncovered ghost ships buried beneath the Financial District, and learned how the changing shoreline has influenced the city’s culinary heritage.
"Climate Week NYC creates an unmatched platform to take complex climate concepts out of conference rooms and bring them directly to people where they live, work, and gather. The appetite for creative, place-based storytelling and tangible solutions is massive, and you will connect with an audience deeply eager to learn and engage." Christa Avampato, Founder, Producer, and Host of NYC's Secrets and Lies
Hosted by the Institute for Responsible Carbon Removal, American University, and the Carbon to Sea Initiative
Legal experts gathered to discuss ideas on how the new Biodiversity Beyond National Jurisdiction (BBNJ) treaty could help govern the emerging field of marine carbon dioxide removal. The roundtable examined how fair and effective regulation could maximize carbon sequestration while reducing risks to people and ecosystems, including in the open ocean, and the legal barriers that could stand in the way.
"Climate Week NYC is an opportunity to bring your message to a global audience." Wil Burns, Co-Director, Institute for Responsible Carbon Removal, American University
Hosted by The Conference Board
A candid discussion on navigating climate risk amid geopolitical instability and shifting policies, facilitated by The Conference Board and CARE, brought business leaders together for a candid discussion on navigating climate risk amid geopolitical instability and shifting policies. Leaders working across sustainability, corporate citizenship, and ESG shared practical insights on turning climate ambition into lasting business action, from strengthening supply chain resilience and advancing decarbonization to securing finance and managing long-term risks.
Hosted by Renewables Grid Initiative
The third session in Renewables Grid Initiative’s Resilient and Optimized Power Grids webinar series explored how circular approaches can strengthen grid supply chains. Highlighting Hitachi Energy’s collaboration with Elia Group, the discussion examined how reusing materials from decommissioned transformers can reduce environmental impacts and ease pressure on critical raw materials, including copper, steel, and aluminum.
"It's important to support such events at the global level, especially in the context we currently stand in, where climate action has been questioned by leadership across countries." Nathália Pimentel, Manager, Renewables Grid Initiative
Hosted by Bracewell LLP and Business Council for Sustainable Energy
Experts were brought together by Bracewell and the Business Council for Sustainable Energy to explore the future of energy investment. Through a fireside chat and panel discussion, speakers examined where capital is flowing, which projects are ready for financing, and the market forces shaping investment in renewables and other decarbonization technologies. A networking reception closed out the event – an opportunity for making more climate connections.
Hosted by MIT Sustainable Supply Chain Lab
MIT researchers and industry leaders launched the 2026 State of Supply Chain Sustainability Report, exploring a growing challenge for corporate sustainability: commitment is rising, but delivery is becoming harder. The discussion examined the impact of geopolitical disruption, fragmented data, Scope 3 emissions, and AI, and why greater efficiency and intelligence do not always translate into more sustainable outcomes.
"Hosting an event at Climate Week NYC was a great experience. It's awesome to bring people together... to really discuss in person, get to the root of an issue, and hear different perspectives. I cannot wait until next year!” Tori Arnold, Project Manager, MIT
From a walk through the seaport to a roundtable on the power grid, these events showed what happens when people from different industries, communities, and backgrounds come together around a shared goal.
At a time when misinformation and greenhushing threaten to quiet the conversation, a global platform like Climate Week NYC matters. Convening thousands of events in one week creates the kind of momentum unmatched by isolated conversations. Climate change is a collective issue that needs collective action. By inviting everyone to be part of the same conversation, we're able to bridge the gap between local communities, corporates, and governing leaders.
