Join us in Brussels on 16 October for this year’s 2025 EU Covenant of Mayors Ceremony, alongisde mayors, regional leaders, and top EU officials, to chart a resilient, secure and prosperous future for Europe together.

As cities across Europe grapple with rising temperatures and the growing risks of extreme heat, they need strong support from national and regional authorities and agencies to adapt. National climate agencies, in particular, can guide local action.

In Covenant of Mayors cities like Vilnius and Zaragoza, local experiments used peer learning and tailored support to make energy renovations more accessible—offering a model for inclusive, community-driven climate action.

The Mayor of Velenje, Slovenia, and member of the EU Covenant of Mayors Board, Peter Dermol, shares how he is guiding the city toward a sustainable and climate-resilient future.
