ISO 14001:2026, the fourth edition of the international standard for environmental management systems (EMS), was published on 15 April 2026 and replaces ISO 14001:2015 together with its 2024 climate amendment. Under the transition timeline that accreditation bodies are applying, ISO 14001:2015 certificates stop being valid on 30 April 2029, and no new 2015 certificates can be issued after 30 October 2027.
Yes. ISO's own record shows the International Standard reached publication on 15 April 2026 as Edition 4, and lists ISO 14001:2015 and ISO 14001:2015/Amd 1:2024 as withdrawn.
The transition rules come from Global Accreditation Cooperation Incorporated (Global ACI), the organisation formed from the merger of the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC). Italy's accreditation body Accredia set out the timeline in April 2026, based on Global ACI's draft transition document:
| Milestone | Date |
|---|---|
| ISO 14001:2026 published | 15 April 2026 |
| Accreditation bodies ready to accredit to the new edition | by 30 October 2026 |
| Certification bodies declare they can manage the transition | by 30 January 2027 |
| Certification bodies' own transition completed | by 30 April 2027 |
| No new ISO 14001:2015 certificates issued | after 30 October 2027 |
| All certified organisations transitioned; 2015 certificates invalid | 30 April 2029 |
Accredia noted it would adjust these rules if the final Global ACI document differs. Confirm the dates your certification body applies; Ireland's NSAI, for example, gave an indicative deadline of 15 April 2029.
The 2026 edition keeps the 2015 framework. ISO describes it as a clearer structure that reflects current environmental challenges. Certification bodies DNV and BSI summarise the main changes as follows:
| Area | ISO 14001:2015 (with Amd 1:2024) | ISO 14001:2026 |
|---|---|---|
| Context of the organisation | Since the 2024 amendment, organisations determine whether climate change is a relevant issue | A broader set of environmental conditions to consider alongside climate change, including pollution, biodiversity and natural resource availability |
| Environmental aspects | Life cycle perspective required | Life cycle perspective strengthened, with attention to upstream and downstream impacts |
| Risks and opportunities | Combined clause on actions to address risks and opportunities | Requirements restructured and clarified |
| Planning of changes | No dedicated clause; changes handled within other clauses | New requirement to plan and manage changes to the EMS (clause 6.3) |
| Operational control | "Outsourced processes" | "Externally provided processes, products and services" |
| Guidance (Annex A) | Existing guidance | Substantially extended guidance across several clauses |
In practice, these changes push your EMS records outward: more attention to what happens in your supply chain and products, and documented reasoning when you change the system.
ISO 14001 certification isn't required by CBAM, ESRS or EcoVadis. What an EMS gives you is a controlled system for environmental data and documents, and that is what each of these asks you to produce.
Companies that already hold ISO 14001 often keep EMS records, EcoVadis evidence and sustainability report data in three separate places, and collect the same figures three times. At Turkish Technic, one data collection fed both the GRI disclosures and the EcoVadis evidence base. The 2026 transition is a good moment to do the same with EMS records. Our sustainability strategy advisory designs the KPI framework and data architecture that connect these outputs, and our EcoVadis advisory and CSRD and ESRS advisory cover the reporting side.
On 15 April 2026. It is the fourth edition of ISO 14001 and replaces ISO 14001:2015 and its 2024 climate amendment, both of which ISO lists as withdrawn.
Yes, during the transition period. Under the timeline accreditation bodies are applying, 2015 certificates stop being valid on 30 April 2029, so the transition audit has to be completed before then.
Global ACI, the body formed from the merger of IAF and ILAC, sets the transition rules for accreditation bodies and certification bodies. Accreditation bodies such as Accredia published the timeline in April 2026 based on Global ACI's draft document.
No. The 2026 edition keeps the existing framework and adds targeted changes: a broader view of environmental conditions, a stronger life cycle perspective, a new requirement for planning changes, and wider control of externally provided processes, products and services.
ISO 14001:2015/Amd 1:2024, "Climate action changes", was published in February 2024. It required organisations to determine whether climate change is a relevant issue when setting the context of their EMS, and it is now folded into the 2026 edition.
It can. EcoVadis draws on company documentation and third-party endorsements such as certifications, so a valid certificate and its supporting records feed the Environment theme. It doesn't replace the policies, measures and results the assessment asks for.
