Looking to work collaboratively with the Department and other stakeholders to address environmental issues and opportunities? A Green Tier Charter may be the fit for you!

A charter is a contract entered into by the DNR and an association committed to helping its members participate in Green Tier. An association may consist of private entities, public entities, or a combination. In a charter, the association must describe its goals, the responsibilities of its members, and the methods its members will use to accomplish their goals. The term of a charter can be between three and 10 years, with opportunity for renewal. Charters help business sectors, regions, supply chains, or other creative groupings of organizations establish and meet environmental objectives.

Don't see a Charter that resonates with you? Perhaps you may want to develop your own! If you think creating a Charter will help advance your organization’s mission, improve collaboration amongst your industry, and are looking to formalize a partnership with the Department, please send an email to We are always looking to hear from industry innovators!

Tier 1

Tier 1 is the most common participation level in the Green Tier program. It is designed to allow companies committed to enhanced environmental protection to distinguish themselves from others. Tier 1 companies are generally environmental innovators with proactive management teams. The DNR is committed to supporting these companies with incentives, including use of the Green Tier logo, that are not available to other companies.

Tier 2

Tier 2 is designed for superior environmental companies. These companies can demonstrate a history of superior environmental performance, and have an effective Environmental Management System (EMS). Tier 2 participants represent the truly exceptional companies that are not only committed to going above and beyond, but are also committed to bringing about change in their industry, region, or within their supply chain.
