About the Competition
Reinventing Cities is a C40 Cities initiative that addresses the urgent need for change in the way that cities are designed and built in response to the climate emergency.
C40 is inviting architects, urban planners, designers, developers, entrepreneurs, environmentalists, start-ups and neighbourhood groups to work together on proposals and compete for the unique opportunity to transform underutilised sites into a model for urban projects of the future.
Fifteen world-leading cities are participating in the initiative in 2022, demonstrating how urban climate leadership and collaboration with the private sector can enable low carbon development and empower communities to live more sustainably. They are:

• Bologna
• Bristol
• Cape Town
• Houston
• Izmir
• Lyon
• Milan
• Montréal
• Naples
• Paris
• Phoenix
• Reykjavik
• Rome
• San Francisco
• Sao Paulo

The winning projects will feature ambitious climate objectives, delivering energy efficiency and low carbon construction, together with a strong emphasis on social inclusion.

 Note: Expressions of interest will be accepted until various dates throughout September 2022—the deadlines vary by city. Consult these site pages for details. The winning projects will be announced in 2023 and will be featured widely across multiple communications channels.
