Following Environmental Management Standards

In addition to our environmental management program, Cleveland-Cliffs uses the International Organization of Standardization’s (ISO) 14001:2015 standard for Environmental Management Systems (EMS).

Our EMS establishes procedures, assigns responsibility, and includes monitoring to verify a myriad of compliance obligations are being properly executed. It helps us anticipate and address potential impacts before they occur.

Our environmental management programs:
