C40 is proud to announce the winning projects of this years’ global youth design challenge Youth Reinventing Cities across 10 participating cities: Amman, Barcelona, Bogotá, Bucharest, Chicago, Jakarta, Lagos, Lisbon, Nairobi, and Rome.

Connecting city leaders with young talent to reimagine real urban sites, the Youth Reinventing Cities competition (formerly Students Reinventing Cities) this year brought together 160 multidisciplinary teams, across 80 universities, challenging hundreds of students and young planners worldwide to tackle urgent urban climate issues.


From bioengineered flood barriers and circular waste networks to school-centred cooling corridors and community care hubs, the winning proposals deliver practical, locally grounded visions for greener, more resilient neighbourhoods across 10 global cities. 


Congratulations to all the awarded teams and to every young person who took part in shaping the future of our cities!

The initiative directly connects city leaders and youth, sharing ideas that inspire city action:

"We join Youth Reinventing Cities because we believe young people are the solution to Jakarta urban challenges. I am impressed by the winning team's creativity to connect sustainability with the people's need for Jakarta. Collaborating with young people means getting fresh ideas and working together to create a better city for the future."Pramono Anung, Governor of Jakarta


“For a city, working directly with young people on a real site is very different from simply asking them what they think about the future. Here, they were given a real challenge and the opportunity to develop real solutions. At the same time city officials had the chance to see the neighbourhood through a different lens”Rareș Hopincă, Mayor of Bucharest’s 2nd District


"The initiative serves as a vital model for engaging youth in solving real urban and climate challenges, turning their creativity into visions for a greener, more resilient city."Ziad Abu Arabi, Deputy City Manager for Planning and Economic Development, Greater Amman Municipality


What's next?

We’re excited to announce that Youth Reinventing Cities returns this November with new sites around the world, new climate goals, and new opportunities for young leaders to make an impact.

Stay tuned
