About the Challenge

The Sustainable Cities Challenge will be delivered over two stages.

Stage 1

Call to cities

We were seeking cities who wish to host City Challenges in 2024 - 2025. Later this year we announced ten shortlisted cities that received a range of capacity building support to help them understand the issue they wanted to solve and attract innovators to provide solutions. By May 2024, we will select three of the ten shortlisted cities to host City Challenges to find solutions for local mobility challenges.

Stage 2

Call to innovators via 3 City Challenges

We have been working with the Host Cities to design local City Challenges which launched between May and June 2024. Each City Challenge offers up to $3million in funding to innovators.

Host Cities have open calls for entries from innovators via their City Challenge with the support of the Sustainable Cities Challenge team. Together, they will then select their finalists to test their solutions in 2024-2025.  In 2026, final awards will given to Winners in each Host City to continue to implement and grow their solutions.


Selected Host Cities call on innovators around the world to tackle their local mobility challenges.
