Colorado Green Business Network


Join us to celebrate and recognize our 2023 CGBN-certified members at our 2023 Colorado Green Business Network Recognition Event at the Denver Zoo on September 29, 2023 from 9 a.m.-12 p.m.! Everyone is welcome.

Program overview


The Colorado Green Business Network (CGBN) is a voluntary program that encourages, supports, and rewards organizations that make the move toward the goal of true, operational sustainability.

Our goal is to support organizations throughout the state at any level of implementation in increasing the efficiency and sustainability of their operation through assessing opportunities for growth, recognizing success, and providing connections to like-minded businesses throughout the state.


We do this through a two-pronged approach by:


  1. Providing free, off-site coaching and on-site assistance to any organization that requests it.
  2. Recognizing and awarding organizations for exemplary practices that lead to resource reduction.

Incentives for joining our network!

There are lots of reasons to join the Colorado Green Business Network. Below we have listed a couple big ones, but don’t forget businesses also often:

  • Reduce: input costs, disposal costs, compliance issues, worker exposure, risk and liability.
  • Increase: performance, customer preference, product differentiation, worker satisfaction and retention.

Networking and community

The incentive most of our organizations often emphasize is the community, which provides:

  • Formal mentoring from Silver and Gold members.
  • Sharing best practices, procedures, and documents.
  • Workshops, facility tours, and events.
  • Monthly newsletters sharing business job openings, new funding opportunities, rebates, and statewide events.

Connection with state and local programs

Another commonly spoken of benefit to the program is the connection with the state, which provides organizations with:

  • Early updates on funding opportunities available through state and local programs as well as utilities.
  • Letters of recommendation in grant applications.
  • Leadership opportunities related to new and upcoming legislation.
  • Priority permitting and regulatory assistance.

Direct installations and project implementation support

During technical assistance, our team provides a number of direct installations which provide businesses with immediate financial savings.
