Environmental Management Systems — Requirements with Guidance for Use
Specifies requirements for an environmental management system: environmental aspects and impacts, compliance obligations, objectives, operational control, emergency preparedness, monitoring and evaluation of compliance. Certifiable, and built on the same high-level structure as ISO 9001 and ISO 45001.
What this does not cover
stated in the document's own scope- It does not set environmental performance limits; those come from permits and law.
- It is not a product standard and does not certify products.
- The 2015 edition and its 2024 amendment were replaced by ISO 14001:2026 in April 2026; certification transition timelines are set by accreditation and certification bodies.
Always verify against the current published text before relying on it for a submission or inspection.
Overview
ISO 14001 sets requirements for an environmental management system that an organisation can use to improve its environmental performance, meet its compliance obligations and achieve environmental objectives. It is certifiable. The 2015 edition, the third, was amended in 2024 to add climate-change considerations. On 15 April 2026 ISO published the fourth edition, ISO 14001:2026, which replaces both. ISO describes the 2026 edition as refining rather than reinventing the framework, with clearer guidance and stronger alignment with climate change, biodiversity and resource efficiency.
Scope & applicability
An organisation’s environmental aspects and its compliance obligations, which in pharmaceutical manufacture include permitted discharge limits and increasing scrutiny of active pharmaceutical ingredients and antimicrobial resistance in effluent. It provides the management-system frame; the binding limits come from permits issued under national environmental law.
Legal basis & how it acquires force
A voluntary International Standard developed by ISO/TC 207/SC 1. It acquires force through certification, customer requirements and, in some places, regulatory recognition. It does not set environmental limits: the binding limits — discharge, emission and waste — come from permits and national environmental law, which the standard requires the organisation to identify as compliance obligations.
Document structure
| Part | Covers |
|---|---|
| Context and leadership | The organisation’s context, interested parties, scope, environmental policy and leadership commitment |
| Planning | Risks and opportunities, environmental aspects, compliance obligations and objectives |
| Support and operation | Resources, competence, communication, documented information, operational control and emergency preparedness |
| Performance evaluation | Monitoring and measurement, evaluation of compliance, internal audit and management review |
| Improvement | Nonconformity, corrective action and continual improvement |
| Annex — guidance for use | Guidance on applying the requirements |
Key requirements
- Clause 4.1 — context, including whether climate change is a relevant issue (Amendment 1:2024)
- Clause 6.1.2 — environmental aspects and the determination of significance
- Clause 6.1.3 — compliance obligations, maintained as a register rather than assumed
- Clause 8.2 — emergency preparedness and response; Clause 9.1.2 — evaluation of compliance
- Amendment 1:2024 adds climate-action considerations to the 2015 third edition
Implementation tips
- The compliance-obligations register is the clause that matters operationally: a permit limit is a numeric operating constraint like a process parameter, and a breach can stop production as effectively as a quality event
- Environmental change in a regulated plant is usually also a GMP change — solvent recovery, single-use versus stainless, reduced HVAC — so route it through both assessments rather than one

International alignment
ISO says the 2026 edition integrates with its other management system standards, which is why ISO 14001 is commonly run alongside ISO 9001 for quality and ISO 45001 for occupational health and safety. In regulated manufacturing, environmental changes such as solvent recovery or utility changes are often also GMP changes and pass through both assessments.
ISO 14001:2015: frequently asked questions
Quick answers to common questions about ISO 14001:2015.
Is ISO 14001:2015 still current?
No. ISO published ISO 14001:2026, the fourth edition, in April 2026, and lists ISO 14001:2015 and its Amendment 1:2024 as replaced.
What changed in the 2026 edition?
ISO describes clearer guidance, more intuitive navigation, stronger alignment with environmental priorities such as climate change, biodiversity and resource efficiency, and greater emphasis on leadership, governance and managing impacts across operations and value chains.
How often are certified organisations audited?
ISO notes that certified organisations usually undergo surveillance audits annually and a recertification audit every three years.
