Silver — Three-year recognition available to organizations that have made a measurable environmental improvement and commit to measuring continuous improvement while a member of the program.

Gold - Three-year recognition available to organizations that have met the Silver Level standard and committed to developing and maintaining an Environmental Management System (EMS) within three years of membership in the program.
