and competition framework

A summary of key information for the competition is outlined below, refer to the Regulation document for detailed guidance.

*Please note that for San Francisco and São Paulo, a dedicated regulation is available to teams on the page dedicate to the city/ site. Please refer to the sites pages for all information.*


Objectives


Reinventing Cities is an international competition initiated by the C40 to stimulate ambitious carbon-neutral developments across the globe and to transform underutilized sites into beacons of sustainability and resilience.

Reinventing Cities will:

  • Drive collaboration between the private and public sector to deliver low carbon urban regeneration; 
  • Support the implementation of inspiring solutions that can be rolled out on a global scale;
  • Help drive forward public policy-making to support decarbonized, sustainable and resilient cities;
  • Accelerate the change and innovation in the global building sector, which is responsible for 40% of emissions.

Therefore, each Reinventing Cities project should serve as a model for carbon-neutral development, demonstrating innovative and replicable climate solutions and providing local community benefits. 


Outcomes


For this competition, cities or public/private site owners propose underutilized sites ready to be released and transformed. Reinventing Cities will enable them to identify and select the best projects for the redevelopment of their sites. 

For each site, the bidding teams will compete to acquire the site and to implement their project. The submitted projects will be holistic from inception, implementation and operation. They must include a financial plan to turn the proposal into reality. 

At the end of the competition process, each city (or site owner) will organize the legal agreement to finalize the site transfer.


Sites


The sites comprise a diverse supply of land with a wide range of sizes and typologies – from existing buildings to empty parcels, and from a small plot in a city centre to a large site in a new development area. 

For each site, the site owner has identified the legal agreement proposed for the site transfer, which can take different forms: sale, lease, concession, lease-back, occupation, joint venture etc.

The sites in competition can be found here.


Teams qualifications


Reinventing Cities encourages new types of collaborations to create ambitious and attractive projects. 
The bidding team must be multidisciplinary and at least include:
  • A qualified person in charge of the project design such as an architect or an urban designer

  • An environmental expert 

  • A developer or investor with the financial capacity to implement the project (mandatory for the final phase, and highly recommended for the initial Expression of Interest phase)

In addition, teams can include other stakeholders such as creative project holders, start-ups, academics, community associations, etc. 

While not required, the team may combine international and local experts, The presence of a local partner is recommended to assist in complying with the local rules and to facilitate local stakeholder involvement.


Competition framework


The competition will be composed of two phases: an Expression of Interest open to all and a Final Phase restricted to the finalist teams. 

For the two phases, the competition is structured by two main documents prepared by the cities/sites owners and C40:

  • A Regulation document

  • For each site, one Site Specific Requirements document (SSR) that outlines the site specifications, including the local rules, the City’s expectations for future uses, and terms of the property transfer.

The bidding teams are expected to submit proposals that comply with the general objectives detailed in the Regulation document and the requirements provided in each SSR. The Regulation document can be downloaded here. The SSRs can be found on each site’s page.

10 challenges for climate


The path to achieving a zero-carbon, sustainable and resilient project requires a combination of solutions. The choice of these solutions should be made in consideration of the site, its configuration, and how it fits in with its surroundings. 

Teams are invited to address the following challenges:

  1. Green buildings and energy efficiency (mandatory)
  2. Clean construction and building life cycle (mandatory)
  3. Low-carbon mobility 
  4. Climate resilience and adaptation 
  5. Sustainable lifestyle and green jobs 
  6. Sustainable water management 
  7. Circular resources and sustainable waste management
