ISO 14001 is a voluntary standard that organizations can certify to.ISO 14001:2015 should be used by any organization that wishes to set up, improve, or maintain an environmental management system to conform with its established environmental policy and requirements. The requirements of the standard can be incorporated into any environmental management system, the extent to which is determined by several factors including the organization’s industry, environmental policy, products and service offerings, and location.

The International Organization for Standardization (ISO) defines an environmental management system as “part of the management system used to manage environmental aspects, fulfill compliance obligations, and address risks and opportunities.” The framework in the ISO 14001 standard can be used within a plan-do-check-act (PDCA) approach to continuous improvement.
