Sustainability Advisory Council



The Sustainability Advisory Council (SAC) was originally created in 2010 by Mayor John Hickenlooper, and continues today under Mayor Michael Hancock. Members of the SAC represent a broad and diverse leadership of Denver’s communities, businesses, and institutions.

The SAC’s primary functions are to:

  • Provide advice and recommendations to the staff of Denver’s Office of Climate Action, Sustainability, and Resiliency (CASR) for advancing the city’s ambitious climate goals and effective implementation of the Climate Protection Fund’s 5-year strategic plan.
  • Assist CASR in connecting with the people, communities, businesses, and institutions it serves.
  • Promote and communicate the principles of sustainability broadly among the community and stakeholders.

The SAC does not:

  • Have the authority to speak for the City and County of Denver or otherwise to commit Denver to any course of action or inaction.
  • Involve itself in policies, decisions, and actions related to personnel.


Sustainability Advisory Council meetings will be held virtually (online) for the foreseeable future. All meetings will be livestreamed for public viewing at

Sustainability Advisory Council Meetings:

Wednesday, May 5, 2021 from 3PM to 5PM

Monday, July 12, 2021 from 5PM to 7PM

Tuesday, September 21, 2021 from 5PM to 7PM

Tuesday, November 16, 2021 from 5PM to 7PM


CASR is committed to seating a SAC and committees that reflect the diversity of people, communities, and businesses in Denver. Membership is open to individuals who live or work in Denver, with the exception of the Science Committee which has no geographic limitation. Members serve for a term of two years and may be reappointed for up to two additional terms at the discretion of the Mayor.
