ISO 14001:2015 was the third edition of the international standard for environmental management systems (EMS). It helped organizations identify and manage their environmental responsibilities, control relevant impacts, meet applicable requirements, and improve environmental performance.
ISO published ISO 14001:2026 on 15 April 2026, replacing ISO 14001:2015 and its 2024 climate amendment. Organizations with an existing 2015 certificate should confirm their transition arrangements with their certification body. Under the applicable Global Accreditation Cooperation Incorporated (Global ACI) transition requirements, the transition deadline for existing ISO 14001:2015 certifications is 30 April 2029. Certification bodies may set earlier operational deadlines.
This guide explains what ISO 14001:2015 covered, its Clauses 4–10, the 2024 climate amendment, certificate validity, tender considerations, and how organizations can prepare for the transition to ISO 14001:2026.

What Was ISO 14001:2015?
ISO 14001:2015 set out requirements for establishing, implementing, maintaining, and improving an Environmental Management System (EMS). It was designed for organizations of different sizes and industries, whether they operate manufacturing facilities, construction sites, offices, warehouses, or service businesses.
The standard provides a structured way to identify environmental aspects, assess related impacts, understand applicable environmental laws and other requirements, set objectives, and monitor performance.
For example, a manufacturing company might identify water consumption, wastewater discharge, energy use, air emissions, and waste generation as environmental aspects. Its EMS would help it assess the related impacts, establish controls, monitor results, and respond when performance fell short of its objectives.
ISO 14001:2015 is now withdrawn and has been replaced by ISO 14001:2026. The earlier edition remains relevant when reviewing existing certificates, historical audit records, and the work needed to transition an EMS.
For the official record, see the ISO catalogue for environmental management standards.
What Changed in the 2024 Climate Amendment?
ISO published ISO 14001:2015/Amd 1:2024, Climate action changes, on 23 February 2024. It introduced explicit climate-change considerations into the existing requirements.
The amendment clarified two areas:
- Clause 4.1 — Understanding the organization and its context: organizations had to determine whether climate change was a relevant issue.
- Clause 4.2 — Understanding the needs and expectations of interested parties: a note clarified that relevant interested parties can have climate-related requirements.
In practice, an organization needed to consider whether climate change affected its operations, environmental risks, objectives, or relevant stakeholder expectations. The assessment depended on the organization’s context; it was not simply a requirement to create a climate policy regardless of relevance.
The 2024 amendment has also been withdrawn as a separate publication and replaced by ISO 14001:2026. See the official ISO amendment record.
ISO 14001:2015 Requirements: Clauses 4 to 10
ISO 14001:2015 followed the common high-level structure used by many ISO management system standards. Its main requirements appeared in Clauses 4–10.
Clause | Main subject | What the organization needed to do |
Clause 4 | Context of the organization | Understand relevant internal and external issues, identify interested parties and their needs, define the EMS scope, and establish the system. |
Clause 5 | Leadership | Establish an environmental policy, assign responsibilities, and ensure that top management supports the EMS. |
Clause 6 | Planning | Identify environmental aspects and impacts, determine applicable requirements, assess risks and opportunities, and set environmental objectives. |
Clause 7 | Support | Provide resources, ensure competence and awareness, manage communication, and control documented information. |
Clause 8 | Operation | Establish operational controls, consider relevant life-cycle stages, and prepare for and respond to potential environmental emergencies. |
Clause 9 | Performance evaluation | Monitor and measure performance, evaluate compliance, conduct internal audits, and carry out management reviews. |
Clause 10 | Improvement | Address nonconformities, take corrective action, and continually improve the EMS. |
This table is a summary of the clause structure, not a substitute for the full standard. Organizations using the 2015 edition needed to consider the applicable requirements together rather than treating each clause as a separate activity.

How the requirements worked together
Consider a manufacturing company that uses large amounts of water and generates wastewater. It would first identify water consumption and wastewater discharge as environmental aspects and consider their potential impacts. It would then identify applicable permits and legal requirements, set objectives, establish operating controls, train relevant staff, and monitor performance.
Internal audits and management reviews would help determine whether those controls were effective. If the company found a problem, it would investigate the cause, take corrective action where needed, and assess whether the action worked. This illustrates how the EMS connects planning, day-to-day operations, performance evaluation, and improvement.
Key Features of ISO 14001:2015
ISO 14001:2015 established a framework for managing environmental responsibilities systematically. Its main features include the following.
1. A common management-system structure: The standard used a structure aligned with other ISO management system standards. This made it easier for organizations to integrate environmental management with systems such as ISO 9001 for quality management, where appropriate.
2. Environmental aspects and impacts: An environmental aspect is an activity, product, or service that interacts with the environment. An environmental impact is the resulting change to the environment.
For example, fuel consumption is an environmental aspect, while the associated greenhouse gas emissions are an environmental impact. Identifying these connections helps an organization determine which issues need controls and monitoring.
3. A life-cycle perspective: A life-cycle perspective means considering relevant environmental effects across the stages of a product or service, such as raw materials, production, transport, use, and disposal. It does not automatically require a full life-cycle assessment for every product. This perspective helps organizations consider environmental effects beyond their immediate operations when those effects are relevant and within their ability to influence or control.
4. Compliance obligations: Organizations need to identify the environmental laws, permits, and other requirements that apply to their operations, understand how they apply, and evaluate compliance at planned intervals. ISO 14001 certification does not itself guarantee compliance with every environmental law. Organizations remain responsible for meeting their applicable legal obligations.
5. Leadership and accountability: Top management was expected to take responsibility for the effectiveness of the EMS, establish an environmental policy, and integrate environmental management into relevant business processes. Responsibilities needed to be assigned and understood.
6. Operational control and emergency preparedness: Organizations need to establish controls for relevant activities and prepare for potential environmental emergencies. Depending on the operation, this might include managing hazardous materials, preventing spills, controlling emissions, or responding to wastewater-treatment failures.
7. Performance evaluation and continual improvement: Monitoring, measurement, compliance evaluation, internal audits, and management reviews helped organizations assess whether their EMS was working as intended. Nonconformities required appropriate action, while continual improvement supported better environmental management over time.
ISO 14001:2015 Certification Process
Organizations seeking certification to ISO 14001:2015 generally followed a process like the one below. The exact process depended on the certification body and the applicable accreditation requirements.
- Define the scope. Identify the sites, activities, products, and services covered by the EMS.
- Establish the EMS. Identify environmental aspects, applicable requirements, risks and opportunities, objectives, responsibilities, and operational controls.
- Implement the system. Provide the necessary resources and competence, communicate relevant procedures, and maintain required documented information.
- Conduct internal audits and management review. Check whether the EMS conforms to the applicable requirements and is operating effectively.
- Complete the certification audit. The certification body reviews the system, commonly through Stage 1 and Stage 2 activities.
- Address audit findings. Where nonconformities are identified, the organization must respond and provide acceptable evidence of corrective action as required.
- Certification decision and ongoing audits. The certification body makes the certification decision. Certified organizations are then subject to ongoing surveillance and recertification arrangements.
ISO publishes standards but does not itself certify organizations. Certification is performed by independent certification bodies. Because ISO 14001:2026 has replaced the 2015 edition, organizations considering a new certification should confirm which edition their chosen certification body is authorized and prepared to certify against.
Can Organizations Still Get ISO 14001:2015 Certification?
The answer depends on the certification body’s arrangements and the applicable accreditation requirements. Do not assume that a 2015 certificate can still be issued simply because the global transition period has not ended.
Global ACI published transition requirements on 14 September 2026. For accreditation bodies and accredited certification bodies covered by those requirements:
- From 31 October 2027, new and initial accredited certifications may only be issued to ISO 14001:2026 certification.
- Existing ISO 14001:2015 certifications must transition by 30 April 2029.
Certification bodies may introduce earlier cut-off dates for accepting applications, conducting audits, or issuing certificates to the older edition. The actual availability of a 2015 certification therefore needs to be confirmed directly with the certification body. For the formal timetable and its scope of application, consult Global ACI’s ISO 14001:2026 transition requirements announcement.
Does an ISO 14001:2015 Certificate Still Valid?
Publication of ISO 14001:2026 did not automatically invalidate every existing ISO 14001:2015 certificate on the day the new edition was published.
However, the 2015 standard is now withdrawn, and certified organizations need to follow the applicable transition arrangements. Under the Global ACI requirements, existing certifications covered by those arrangements must transition by 30 April 2029. A certification body may require action earlier. The status of an individual certificate also depends on its own terms and circumstances, including whether it remains active and has not been suspended or withdrawn. If your organization holds a 2015 certificate:
- Check the certificate’s status and expiry date.
- Contact the certification body that issued it.
- Confirm the transition deadline and available audit arrangements.
- Check whether any customer, regulator, or procurement requirement imposes an earlier deadline.
Do not rely on the publication date of the new edition alone to determine the status of your specific certificate.
ISO 14001:2015 for Government Tenders and GeM
Organizations may refer to ISO 14001 certification when responding to government tenders, GeM opportunities, or other procurement requirements. Acceptance depends on the wording of the relevant tender or procurement document. A tender may specify an ISO 14001 edition, require a valid certificate, or set conditions concerning the certification body’s accreditation. A certificate to an older edition should not be assumed to satisfy every current requirement. Before submitting a bid, check:
- Required edition: Does the tender specify ISO 14001:2015, ISO 14001:2026, or simply ISO 14001?
- Certificate validity: Is the certificate active and valid for the required period?
- Scope: Do the certified activities, products, services, and sites match the tender requirements?
- Certification and accreditation: Does the issuing certification body meet the tender’s stated conditions?
- Clarification: If the edition or transition status is unclear, request clarification from the tendering authority before submission.
The same checks apply when using a certificate for customer qualification or supplier approval. Neither the older nor the newer edition should be assumed to guarantee acceptance without checking the applicable conditions.
How to Transition from ISO 14001:2015 to ISO 14001:2026
Organizations should work with their certification body to establish a transition plan that reflects their certificate status, audit schedule, and applicable deadline. The following roadmap can help organize the work.
- Confirm the applicable deadline. Ask your certification body for its transition cut-off and audit requirements.
- Review the 2026 edition. Obtain the official standard and identify the requirements relevant to your EMS.
- Assess gaps. Compare the existing system with ISO 14001:2026 and record the changes needed.
- Update the EMS. Revise relevant processes, controls, objectives, risk assessments, and documented information.
- Inform and train relevant personnel. Make sure people understand any changes that affect their responsibilities.
- Verify implementation. Complete internal audits and management review as appropriate, and address identified issues.
- Coordinate the transition audit. Agree the audit arrangements with your certification body, complete the required activities, and address any nonconformities within the applicable timeframe.
Start early enough to allow time for implementation and corrective action. A gap assessment is useful, but it does not replace reading the official standard or following the certification body’s requirements.
Why ISO 14001:2015 is Still Important
ISO 14001:2015 established the environmental management framework many organizations have used to identify impacts, manage compliance obligations, set objectives, and evaluate performance.
For organizations already using that edition, understanding its requirements helps explain the structure of their current EMS, interpret historical audit findings, and identify what needs to be reviewed during transition. Its withdrawal does not remove the value of existing records or the environmental controls an organization has put in place. The practical priority is to maintain an effective EMS while preparing for the applicable transition requirements.
