Denver Department of Public Health and Environment (DDPHE) is committed to ensuring marijuana facilities operate safely with little environmental impact.

In early 2016, DDPHE 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 the Cannabis Environmental Best Practices Guide in October 2017. The purpose of the Guide is to provide cannabis cultivation businesses with a snapshot of relevant sustainable practices and a starting point for process optimization techniques that facilitate continual improvement. The Guide was written with input from sustainability experts and numerous stakeholders in the cannabis industry. If you have questions, or would like to contribute to future updates to the Guide, please email
