Climate Alliance International Conference 2025

As international climate frameworks falter and national governments increasingly divert their focus from climate issues, the task of advancing, delivering and inspiring climate action is falling progressively more to regions, cities and towns. In the coming years, the climate movement will primarily come from bottom up. And now more than ever, it has to.

Combatting energy poverty, planning local heating and cooling networks, and adapting our cities and towns to a changing climate all squarely take place on a municipal level. But also when it comes to communicating with citizens on climate action, fostering the energy transition on the ground and developing global climate partnerships, cities and towns are drivers of the transition we so urgently need.

On the basis of best practice examples as well as failures and lessons they provide, the 2025 Climate Alliance International Conference (CAIC25) will showcase municipalities and regions that are taking climate matters into their own hands. Join us in Cologne for fresh perspectives on how local and regional governments across Europe are advancing, delivering and inspiring climate action now.

CAIC25 is organised by Climate Alliance and the City of Cologne in cooperation with NRW.Energy4Climate, the regional organisation for energy and climate protection, and Kommunal Agentur NRW.

The Covenant of Mayors will be present with its #CitiesRefresh Campaign.
