This document outlines the key components and steps to establishing an effective Environmental Management System (EMS) according to ISO 14001. An EMS is a systematic approach used by organizations to develop and implement their environmental policy and manage their environmental impacts. The main components include developing an environmental policy, planning objectives and targets, implementing operational controls, checking performance, and reviewing to ensure continual improvement. Effective implementation requires commitment from top management and addressing potential barriers such as lack of resources or clear responsibilities.
