Heatwaves, devastating wildfires polluting our skies and lungs – and the choice to do something about it. Here's why you can’t miss this year's Climate Week NYC.
Climate Week NYC returns to New York City from September 20–27, 2026, alongside the UN General Assembly. That means Heads of Government, ministers and Secretaries of State are in town to collaborate with businesses and NGOs, make decisions, and drive action.
Here’s why you need to join them in New York City in September.
1. The world is at a genuine turning point
Conflict and geopolitical instability have catapulted energy security to the top of the global agenda. At the same time, heatwaves, wildfires and other climate impacts are intensifying across the globe. These events are coming together into a single, urgent question: how fast can the world move to a clean, secure energy system?
That’s why this year’s theme is Energy. Impact. Action.
Energy for the transition and the urgency behind it, Impact for the outcomes that matter, and Action for meaningful, lasting change.
2. The business case has never been stronger
As economies electrify, the case for renewables and storage goes from strength to strength. Trillions of dollars have already been unlocked over the past few years across energy, transport, buildings and industry. Businesses moving early on the transition are securing lower costs, more resilient infrastructure, and long-term certainty in an uncertain world.
Money is moving. Decisions about where it flows next are made at Climate Week NYC.
3. It's laser-focused on what's holding back progress
We have all heard that ‘we have the solutions – it’s now time to implement them’. So what’s holding us back? Ambition alone doesn’t cut it. The switch to a clean energy system should be accelerating, but outdated permitting rules, grid bottlenecks and vested interests in polluting energy are slowing it down, market by market. This year, the world’s leading and most dynamic climate event is turning momentum into real-world impact: modernizing regulation, clearing the barriers, and making the case for a fast, clean and fair electrification of the world's economies.
We’re here to remove the barriers to a cleaner, healthier and more stable world.
4. Innovation and AI take center stage
Technology is reshaping the energy conversation as fast as geopolitics is. AI is driving new demand for power, but also opens up new ways to meet it – from smarter grids to faster deployment of the clean energy solutions already unlocking progress.
Climate Week NYC 2026 brings together the people who build these tools with the people deciding how fast they scale.
5. It's where the decisions get made
Held alongside the UN General Assembly, and organized by Climate Group for almost two decades, Climate Week NYC brings heads of government, business leaders, investors and innovators to New York. Beyond the headline events – the Opening Ceremony and The Hub Live – the program spans hundreds of sessions, events and gatherings. It sets the stage for CEOs, Indigenous people, farmers battling dry soil, activists, artists, and communities trying to adapt to a changing world. It brings the world to New York City – for the world.
This is where urgent climate action happens.
