Colorado Green Business Network

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.

To learn more about our program, please check out our CGBN program overview (Spanish version), as well as the pages below!

Incentives for joining our network!


There are lots of reasons to join the Colorado Green Business Network. The incentive most of our organizations often emphasize is the networking and community opportunities. Another commonly spoken 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 and letters of recommendation in grant applications. As a part of the CGBN, organizations can also reduce input costs, disposal costs, compliance issues, worker exposure, risk and liability and increase performance, customer preference, product differentiation, worker satisfaction and retention.
