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 will work closely with the Selected Cities to design and launch three local City Challenges with up to $3 million in funding available for innovators by mid-2024.

Selected Cities will call 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 2025 and beyond, funding will be available for winners in each Selected City to continue to implement and grow their solutions.
