In December of 2015, the Department of Environmental Health released an updated Climate Action Plan. As part of that plan, Mayor Michael B. Hancock announced Denver’s goal of reducing community Greenhouse Gas (GHG) emissions 80 percent below 2005 levels by the year 2050 (80 by 50). Mayor Hancock also commited the City to pursuing a robust stakeholder process to identify and vet potential strategies to get Denver to that goal.

Since the Mayor's announcement, DEH has been hosting the stakeholder process. DEH is supported in this effort by Lotus Engineering & Sustainability.

Those who live and/or work in Denver are encouraged to provide input on the 80x50 Climate Goal by taking the survey below. The survey results will provide additional considerations to strategies, targets and visions developed by the 80x50 Climate Goal Stakeholders.


Read the 80x50 Climate Goal Stakeholder Report



Denver Environmental Health and the Colorado Chapter of the Sierra Club are hosting "Denver Climate Conversation" on November 20 from 5 8 p.m. at the McNichols Building on the 3rd floor. The event will include a movie screening and panel that discuss the local impacts of climate change and actions in being taken in Denver.

Mayor Michael B. Hancock will open the event by introducing the free screening of “From the Ashes.” Following the movie, a panel of climate science, labor and health experts will facilitate an informal climate action networking hour.

“From the Ashes” is a compassionate documentary presenting compelling stories from coal communities, and what is at stake for our economies, public health and climate. It features the voices and perspectives of environmentalists, coal miners, climate scientists, law makers, ranchers, elected officials and residents affected by coal plant closures.

Attendees can also weigh in on the 80x50 Climate Goal Stakeholder Report as part of a community input process to help shape Denver’s efforts to address climate change.

Technical Advisory Committee

This committee worked to create a broad list of transformative systems-based approaches to GHG reductions within four distinct sectors: Mobile Supply, Mobile Demand, Stationary Supply and Stationary Demand. This group drew from academic/non-profit expertise and research institutes related to the four sectors. The group's outcome formed a summary matrix of potential strategies to achieve the 80x50 GHG reduction goal but will not be limited by advanced analysis of economics, feasibility or other constraints.

Task Force

This group worked to integrate the summary matrix into a larger transformative framework. These systems thinkers wove together the technical, financial, market, regulatory and social factors that impact energy systems into a plan that meets the 80x50 target. They provided insight into the opportunities, barriers and “ground truthing” of the advisory committee’s initial list of strategies. The task force identified the barriers and opportunities presented by the technical committee’s recommendations and categorized short-, medium- and long-term strategies, ensuring they are equal to or greater than the projected necessary reductions.
