Cities send us their local sustainability issues and from there we create a Program to present to the City Representatives innovative and relevant solutions to solve their local issues. 

→ Come and share what your City is implementing
→ Get on track with your local objectives!
→ Get inspired by other Cities
→ Connect with changemakers

Guided tours

Guided tour at our Hall of Solutions where Cities meet with entrepreneurs that address their local issues and imagine what our cities can be like.

Networking times

One-on-one meetings, bilateral meetings, breakfast, cocktail... specifically organized to boost the cooperation between all actors working to build sustainable cities.



The solutions presented to Cities meet specific criteria. Our partnership with the European Covenant of Mayors for Climate & Energy  is strategic to help develop solutions to our major climate challenges. Cities are home to the majority of the world's population. It is in this environment that the innovative solutions needed for a sustainable world must be built. ChangeNOW is a place to make it happen!

"Cities have always been at the forefront of change. They have always paved the way for future progress.
That makes them today decisive actors in the ecological and energy transition.
But we can only operate this revolution - political, social, cultural - with the citizens, not just for them."

Anne Hidalgo, Mayor of Paris
