Certificates

ISO 14001

Werner & Mertz has been ISO 14001-certified at its production sites for years. The ISO 14001 is an internationally valid Environmental Management System (EMS) based on private law. In countries outside Europe (e.g., Japan), this certificate verifies our use of a management system that is also recognized there.

Internationally recognized: The environmental management system of Werner & Mertz.

ISO 14001 relies on a Continuous Improvement Process (CIP) to achieve defined environmental targets. This process, which Werner & Mertz defines as "improve the good and develop it further", covers the ISO four-step process known as "Plan-Do-Check-Act".
