Cannabis Sustainability

Denver Public Health & Environment (DDPHE) works collaboratively with city, state, and community partners to conduct education, community engagement, and enforcement to ensure healthy people, healthy pets, and a sustainable environment. This includes working with local businesses, including the cannabis industry, to identify and reduce environmental impacts. Cannabis cultivation and processing is relatively new industry with significant potential environmental impacts related to energy and water use, pesticides, solid and hazardous waste, etc. DDPHE is committed to partnering with the industry and stakeholders to educate the industry and assess impacts. 


The Cannabis Sustainability Work Group was formed in 2016 with a mission to promote sustainability in the cannabis industry through education, the development and dissemination of best practices, and the facilitation of dialogue between the cannabis industry, the community, and technical experts. Members of the workgroup represent a variety of stakeholders, including cannabis business owners, consultants and contractors, government, and sustainability and policy experts. Each member of the Work Group participates in one of four committees: Events & Outrech, Best Management Practices & Data, Policy, or Symposium. Ten new members are joining Denver’s Cannabis Sustainability Work Group in 2019.
