A global competition for innovative, zero-carbon and resilient urban projects

4th edition launched!

Reinventing Cities is a global competition that seeks to accelerate the development of decarbonised and resilient urban regeneration across the globe.

Through this competition, cities identify under-utilised sites that are ready to be released and transformed and invite creative multi-disciplinary teams - including architects, planners, developers, investors, environmentalists, creative project holders, start-ups, academics and community associations - to submit proposals that can serve as a model for city landmarks of the future.

Reinventing Cities has now launched its fourth competition in 15 global cities: Almere, Bilbao, Bologna, Brussels, Glasgow, Milan, New York, Palermo, Renca, Rome, San Antonio, San Francisco, São Paulo, Seattle and Venice.

Reinventing Cities Highlights

Words from Mayors

Climate change and global warming present an existential threat to the human race and will require a unified global response at all levels of society. Scientists estimate that we are currently on a trajectory that will increase average global temperatures by two degrees above pre-industrial levels by 2100. If these emissions are not appropriately addressed, cities will become increasingly vulnerable to the adverse impacts of climate change.

At the heart of the city lies an opportunity, as urban density presents a greener way of living. Urban density can create the possibility for a better quality of life and a lower carbon footprint through more efficient infrastructure and improved urban planning.

Therefore, cities and private actors must work together to showcase new models for decarbonized development, buildings, and services to households and businesses in hopes for their widespread uptake and adoption.

As Mayors, we are committed with the C40 to move a step forward in our fight against climate change and to organize Reinventing Cities, an unprecedented global competition to stimulate sustainable development and to celebrate innovative solutions to environmental and urban challenges.

We hope Reinventing Cities will set new standards of carbon-neutral and resilient development and will enable the implementation of projects across a wide range of architecture practices, typologies and uses. With this competition, we are calling the private actors to work with us to identify new solutions and to deliver the city of tomorrow, today.
