Climate Week NYC is the world’s largest climate event and a global platform for advancing climate and economic progress at scale.
Each year, it brings together more than 100,000 people across 1,000+ 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.
This year's Climate Week NYC will focus on the energy, the impact, and the action that we drive together.
The context is shifting fast. Energy systems are being redesigned, supply chains are under pressure, and demand for electricity is rising, driven by electrification, AI and digital infrastructure. At the same time, the transition is unlocking new sources of growth, investment and long-term competitiveness.
The challenge now is not ambition, but implementation. Progress is being slowed down by outdated regulation, infrastructure constraints and misaligned markets. The priority is to remove these barriers and deliver change at speed and scale.
Climate Week NYC exists to accelerate that progress.

Why New York, why now
Climate Week NYC takes place alongside 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.
We realize Climate Week NYC this year dates coincide with Yom Kippur – sadly, it’s unavoidable as our event is held alongside the UN General Assembly. We still hope you can join.
