C40: Reinventing Cities Competition

May 4, 2018

Reinventing Cities is an unprecedented global competition organized by the C40 to drive carbon neutral and resilient urban regeneration.

Together 19 cities have identified 49 underutilized spaces, rapidly available for redevelopment. The initiative invites developers, architects, environmentalists and creative minds to collaborate and compete for the opportunity to transform these sites into beacons of sustainability and resiliency.

The competition will serve as a model, demonstrating how the alliance between cities and business can shape the future delivering healthier, greener and economically viable urban development.

How it Works:

The Reinventing Cities competition helps cities identify and select the best projects to redevelop underutilized sites in cities around the world.

Participating cities propose a diverse supply of land, including empty plots in new development areas, sites to densify in City centres, abandoned buildings, historical mansions, former industrial sites, underused car parks, etc…

For each of these sites, the bidder teams will compete to buy or lease the site and to implement their project. Projects should address components such as energy efficiency, sustainable building materials, circular economy, water management and other components that will lead to a resilient and carbon-free development.

The price won’t be the main criteria for the project selection. Supported by C40, the cities will favour bids from creative teams that deliver innovative climate solutions in combination with striking architecture and tangible benefits for the local community.

An Unprecedented Competition:

Beyond business as usual, Reinventing Cities targets climate-oriented project

Beyond a call for ideas, Reinventing Cities targets real-life projects. It will lead to a property transfer enabling the winners to implement their project

Beyond a simple design competition, Reinventing Cities targets holistic projects with innovative program, design and construction methodology

Beyond frontiers, the Reinventing Cities teams will gain international exposure. They will be presented as pioneers, committed alongside Mayors to develop new models of carbon neutral and sustainable development.
