An EMS is a continual cycle of planning, implementing, reviewing and improving the processes and actions that an organization undertakes to meet its business and environmental goals. Most EMSs are built on the "Plan, Do, Check, Act" model. This model leads to continual improvement based upon:

• Planning, including identifying environmental aspects and establishing goals [plan];
• Implementing, including training and operational controls [do];
• Checking, including monitoring and corrective action [check]; and
• Reviewing, including progress reviews and acting to make needed changes to the EMS [act].
