In early 2016, DEH developed the Cannabis Sustainability Workgroup to determine best practices, and develop a manual and other educational resources for the industry. Workgroup members include industry leaders and groups, local government, and consultants.

Denver’s Cannabis Sustainability Work Group promotes sustainability through the development and distribution of best management practices and facilitation between the cannabis industry, community, and energy and sustainability experts. The work group strives to develop realistic, impactful, and verifiable guidelines supported by data about the industry’s baseline impact on the environment and measurements of reductions in negative impacts.

On October 26th, over 200 people gathered at the Colorado Convention Center for the inaugural Cannabis Sustainability Symposium. Hosted by the Organic Cannabis Association with in-kind support from Denver Environmental Health, the event was the first full-day conference dedicated to education on sustainability issues in the cannabis industry. The symposium attracted an international audience from a variety of backgrounds, including cannabis industry professionals, government, students and sustainability professionals.

The sessions at the symposium covered six topics: energy efficiency, water conservation, waste management, integrated pest management, community engagement and design for efficiency. Each session featured a panel of experts that provided their unique perspective on the given topic area. Slides from each session are available on the symposium website,

During the energy efficiency session, Brad Queen (pictured below) of Cube Resources explained how installing energy monitoring equipment at cultivation facilities in Boulder County led to a better understanding of energy use, costs and peak demand. Joel Salatin, owner of Polyface Farms, provided a colorful keynote address on the challenges of alternative agriculture. 

The day concluded with a happy hour reception held at the Alliance for Sustainable Colorado, where attendees took advantage of the time to network and continue discussions begun during the sessions.

Members of the Cannabis Sustainability Work Group collaborated on the planning and production of symposium, from inviting speakers to moderating panels. “The 2016 Cannabis Sustainability Symposium was a huge success, and we’re looking forward to expanding and improving next year’s event,” said Emily Backus, the Cannabis Sustainability Work Group co-chair.
