Hosted by Climate Group, Climate Week NYC is the world’s leading climate event and a global platform for accelerating climate and economic progress at scale, bringing together the people turning solutions into real-world change.
Each year, it brings together more than 120,000 people across 1,500+ events in New York City. From global leaders shaping markets and policy to communities driving change on the ground, it connects the people and ideas building a low-carbon economy and a more secure future.
In 2026, Climate Week NYC took place against a rapidly changing backdrop. Energy systems were being redesigned, supply chains were under pressure, and demand for electricity was rising, driven by electrification, AI and digital infrastructure. At the same time, the transition was unlocking new sources of growth, investment and long-term competitiveness.
The message from the week was clear: the challenge is no longer ambition, but implementation. Outdated regulation, infrastructure constraints and misaligned markets are still slowing progress, and removing these barriers to deliver change at speed and scale remains the priority.
As we look ahead to 2027, Climate Week NYC will continue to bring together the leaders, innovators and decision-makers driving that progress forward.

Why New York, why now
Climate Week NYC takes place in coordination with the UN General Assembly, when global leaders from business, government and civil society are already in the city.
New York sits at the intersection of finance, policy and global influence. It creates a unique moment to align priorities, form partnerships and shape decisions that will impact the direction of the global economy.
Who is the week for?
Climate Week NYC convenes people who can shape and deliver change, across business, government, finance and civil society.
It brings together those directing capital, setting policy, building infrastructure and driving implementation on the ground, alongside the communities and organizations pushing progress forward.
Participants come to Climate Week NYC to understand what’s changing, connect with the people shaping the transition, and act on the opportunities ahead. As a catalyst for progress, it brings together in-depth discussions and the decisions that will reverberate for years to come - where businesses build partnerships, policymakers and investors align priorities, and organizations and communities scale their impact.
