UNSG High-level Event on Climate Action and the Just Transition 

Not Open to the Public

The Secretary-General will convene a high-level meeting on climate action and the just transition focused on accelerating a just and orderly energy transition to renewables; mobilizing and scaling up affordable finance and investments for developing countries; and delivering adaptation and resilience support in an era of climate overshoot.

The Climate Summit 2026 will feature an interactive leaders' dialogue as well as a series of multi-stakeholder thematic solutions dialogues.

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.
