ISO 14001 is the international standard that specifies requirements for an effective environmental management system (EMS). It provides a framework that an organization can follow, rather than establishing environmental performance requirements.

Part of the ISO 14000 family of standards on environmental management, ISO 14001 is a voluntary standard that organizations can certify to. Integrating it with other management systems standards, most commonly ISO 9001, can further assist in accomplishing organizational goals.

The International Organization of Standardization (ISO) defines an environmental management system as “part of the management system used to manage environmental aspects, fulfil 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.
