A Climate Week NYC overview

Climate Week NYC is the largest annual climate event of its kind, bringing together some 400 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 is hosted by Climate Group, an international non-profit whose purpose is to drive climate action, fast. Climate Group hosts the official program during the week that brings together the most senior international figures from business, government, civil society and the climate sector.

This year Climate Week NYC will be held from September 17-24, 2023. The event takes place every year in partnership with the United Nations General Assembly and is run in coordination with the United Nations and the City of New York.

Main events taking place

This year Climate Week NYC is presenting a full program of some 400 events and activities in New York City. For those unable to attend in-person, we’ll be streaming key sessions throughout the week. Wholly digital events will also be included in Climate Week NYC’s Events program.  

The Climate Week NYC Opening Ceremony is the most high-profile moment of the week. Taking place on Sunday, September 17, the event will feature major announcements, discussions, and interviews with international leadership from business, government, and the climate community. Recent speakers include Prince Charles, Tim Cook, Jacinda Adern, the Hon. Chris Bowen, Kristalina Georgieva, Kathy Hochul, and Dr. Ngozi Okonjo-Iweala.

This year the Climate Week NYC Opening Ceremony will cover three key themes:  

  • How can and will we meet the challenges of the latest IPCC report in the face of delays and the use of fossil fuels not coming down fast enough?
  • What does deep, systemic change look and feel like? What are the next frontiers – and opportunities?
  • How do organizations prepare for a radically different economy?  

On Monday and Tuesday, September 18 and 19, 2023, Climate Group hosts The Hub Live. Bringing together more than 1,000 of the most influential leaders from business, government, and the climate sector, The Hub Live hosts a series of sessions addressing key themes which will be shared at a later date.

The theme is We Can. We Will

The theme reflects determination, focus, but also a hopeful promise, and a call to action to do it together. It touches upon the action we need to take now, but also the need to look ahead and explore new opportunities.

We've seen some promising wins when it comes to renewables and financing, but we can’t rest on our laurels. We're entering a new phase where we need to look at what comes next: tripling clean investments, finding new solutions, taking concrete action, exploring new opportunities and solutions, and breaking down barriers together.

We expect this year’s Climate Week NYC to be even bigger than 2022, which was the most impactful, ambitious, and far-reaching one to date. Business leaders, political change makers, local decision takers and civil society representatives are set to use the week as a rallying call for the meaningful contributions still needed to halve carbon emissions by 2030 and to be on a path to net-zero by 2050.
