An Environmental Management System (EMS) is a set of processes and procedures that can enable an organization to reduce its environmental impacts and increase its operating efficiency. An EMS is an effective tool for businesses, institutions, municipalities, and other organizations with intensive utility use or manufacturing facilities. DNR Pollution Prevention Services provides guidance and technical assistance to assist Iowa organizations in all phases of the EMS process.
EPA's EMS Website provides a general description of the EMS process, including the "plan, do, check, act" model and benefits of an EMS. It also provides detail on key EMS steps, including gap analysis, policy, aspects and impacts, objectives and targets, EMS implementation, and management review.
