In 2013 the Office of Sustainability was created through Executive Order 123 by Mayor Michael B. Hancock, as a successor to Mayor John Hickenlooper’s Greenprint Denver Office. The mission of the Office, as described in Executive Order 123, was “to provide leadership, guidance, and coordination to city agencies to implement its pursuit of sustainability,” with oversight on several subject areas, as noted by chapters in the document. Each chapter, as laid out, sets the standards for those subject areas within the City & County of Denver operations.
In 2019, Mayor Michael B. Hancock and City Council combined the Environmental Quality Climate Team with the Office of Sustainability to create a new office, the Office of Climate Action, Sustainability, and Resiliency through the passing of Bill 19-1177. This office continues to oversee Executive Order 123 in addition to the 80x50 Climate Action Plan and several other programs and initiatives.
Executive Order 123 requires all city construction (horizontal and vertical) to be built to a minimum sustainability standard as called for in the Greenprint Denver construction forms, which can be found below.
