Denver Environmental Health (DEH) is committed to ensuring marijuana facilities operate safely with little environmental impact.

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.


The Cannabis Sustainability Work Group released a public draft of the forthcoming Environmental Best Management Practices Guide. The Work Group is accepting public comments on this document through August 13. Please email any questions or comments on the draft guide to Comments received after August 13 will be recorded but not considered for inclusion in the guide. The final guide will be released prior to the Cannabis Sustainability Symposium in October.
