In June, a group of 125 of Denver’s public-, private-, and nonprofit-sector leaders came to study Copenhagen’s brand of sustainable urbanism with the Denver Downtown Partnership (DDP) Urban Exploration program. The DDP study group included 61 members of ULI Colorado, Denver Mayor Michael B. Hancock, several Denver City Council members, and city and county staff members. The study tour explored the city of Copenhagen “through three lenses: livability, equity, and economic innovation, in which growth goes hand-in-hand with quality of life,” said one official.
