Denver strives for all businesses to operate as sustainably as possible. We work to research and share best practices in the cannabis industry to reduce their climate and environmental impact and partner to advance programs and policy.


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.
