Climate Summit 2026
23 September, United Nations Headquarters, New York
This Climate Summit, convened by UN Secretary-General António Guterres, will bring together leaders from major economies, developed and developing countries, vulnerable nations, and major energy producers and consumers to strengthen cooperation at a pivotal moment.
Ten years after the Paris Agreement, the climate crisis has entered a new phase in which overshoot is now inevitable, while the energy transition accelerates. Leaders will take stock of progress and set out how they will work together to accelerate the transition, strengthen energy security, advance climate justice, and protect people from an accelerating climate crisis.
