Is an Environmental Management System (EMS) required for Green Tier?
Wisconsin’s Green Tier program places great value on Environmental Management Systems (EMS). Tier 1 participants must have an ISO-14001 certified or a functionally equivalent Environmental Management System (EMS) in place within the first year of participation. Tier 2 participants must have a well-developed EMS (ISO certified or functionally equivalent) at the time of application with a documented history of results.
