ISO 14000 is primarily concerned with the environment, or with what an organization does to manage the impact of its activities on the environment. ISO 14000 is a series of environmental management standards developed by the ISO which provide requirements, guidelines, and tools for implementing an environmental management system (EMS). It provides a standardized model for an EMS created through international consensus.

ISO 14001 is the requirement standard of the ISO 14000 series. Today, it is the most widely recognized standard for environmental management in the world. There are four ways to exhibit successful adoption of ISO 14001: self-declaration; audit by an interested party such as a client; external audit; and obtaining certification/registration. As with other management system models developed by the ISO, the model is based on Deming’s PDCA cycle for continual improvement.
