An environmental management system is the part of an organisation's management system used to develop and implement its environmental policy and manage its environmental aspects — a continual-improvement framework standardised internationally as ISO 14001 (2015; revised 2026). It applies the Plan-Do-Check-Act cycle: policy, aspect identification, objectives, operational controls, monitoring, audit and management review.

Overview
What it means
ISO 14001 belongs to the ISO 14000 family of voluntary environmental standards, which also covers environmental auditing, performance evaluation, labelling and life-cycle assessment. Certification provides external assurance; the EU EMAS scheme adds public environmental statements.
Under the EU Energy Efficiency Directive, certified environmental or energy management systems can substitute for mandatory energy audits.
How it is used
Used by companies and public bodies to structure compliance, reduce impacts, meet buyer requirements and support sustainability reporting.
Why it matters
EMS is the dominant organisational architecture for environmental performance worldwide and the substrate for many regulatory and procurement regimes.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
