That’s a wrap on the first Rethink Cities Summit!
On 8–9 September, over 100 participants from 26 cities across Europe joined us in Sønderborg to rethink the future of urban energy transitions. 🌍
The energy, insights and collaboration you brought made this first edition truly special. 🙌
Together we:
✔️ Engaged with businesses and innovators driving the transition
✔️ Explored Sønderborg’s progress on three inspiring field trips
✔️ Learned from successful cases across European cities
✔️ Took on real challenges in hands-on workshops focused on urban energy transition
We believe seeing is believing and at the Rethink Cities Summit we showed what's possible when public-private partnerships, political will and citizen engagement align. ✨
But true impact doesn’t stop at inspiration. It comes from scaling what already works.
Thank you to our partners Sønderborg Municipality (), ProjectZero (), Bitten & Mads Clausen Foundation, Danfoss (), Urban Impact (.agency), Net Zero Cities, IDA Energi (), ICLEI, EIT Urban Mobility, and iChoosr (). Your support was instrumental in making the summit a success.
And to all our local and international collaborators, thank you for bringing the summit to life with your experience and dedication.
