Congratulations to the first 15 winners of C40's Reinventing Cities competition!
These innovative and replicable climate solutions will serve as examples for other cities to reimagine urban development and to drastically reduce the carbon footprint of new and existing buildings, which today account for more than 50 percent of emissions in C40 cities. The 15 winning teams of architects, urban planners, designers, developers, entrepreneurs and innovators were selected by juries in each city, from amongst 82 finalist teams.
