ISO 14001:2026, the fourth edition of the international standard for environmental management systems, was published in April 2026. It replaces ISO 14001:2015 and incorporates the 2024 amendment on climate change. ISO's own description of the revision is short: the text now follows ISO's current drafting rules for management system standards, and requirements on key topics are made clearer. For certificates issued by ASCB-accredited certification bodies, the transition deadline is April 30, 2029. After that date only the 2026 edition applies.
The transition timeline
The move to the new edition happens over a transition period, not at the moment of publication. Certification against ISO 14001:2015 may continue for bodies not yet transitioned until April 30, 2029. After that date only the 2026 edition applies.
When and how a particular certificate moves to the new edition, including what the certification body will assess and at which visit, is for the certification body that issued it to set out, so an organization planning its move should agree the detail with that body. The standard's own current status is shown at iso.org.
What changed in the 2026 edition
Much of the standard is unchanged. Leadership, the environmental policy, environmental aspects, compliance obligations and operational control are substantially as they were in 2015. The changes are these:
• The climate change requirement added by the 2024 amendment is now part of the standard. When an organization determines its context, climate change is named among the environmental conditions it considers, alongside pollution, the availability of natural resources, biodiversity and ecosystem health.
• Determining risks and opportunities has its own subclause, 6.1.4, with planning of action at 6.1.5. What has to be determined is the same in substance as in 2015.
• A new clause, 6.3, requires changes to the environmental management system to be planned.
• Management review is divided into three subclauses: general, inputs and results. "Results" replaces the 2015 term "outputs".
• Clause 10 is reorganized: continual improvement moves to 10.1, and nonconformity and corrective action stays at 10.2.
• Documented information is now required to be available, in place of the 2015 wording of maintaining and retaining it. Annex B of the 2015 edition, the correspondence tables, is removed, and the standard now has an index.
Each change is set out against the clause text of both editions in the ISO 14001 overview in the Standards Library.
What the revision means for a certified organization
An organization with a well-run environmental management system will recognize the framework it already operates, and an organization that applied the 2024 climate change amendment has nothing new to do on that requirement. Several of the changes are to structure and wording rather than new obligations; the new clause on planning changes is the main addition. The attention falls where the structure has moved: risks and opportunities determined and documented under their own subclause, changes to the system planned, management review recorded against its three subclauses, and documented information available when it is needed.
The transition itself is assessed by the certification body that issued the certificate, within the period above. Confirming the timing and detail with that body is the starting point for any organization planning its move.
What it means for the users of a certificate
A certificate citing ISO 14001:2015 remains a current certificate during the transition period. It does not become invalid when the new edition is published. A buyer reading certificates during the transition may therefore see either edition cited, and both carry the same weight until the deadline. As at any other time, the certificate's current status can be verified, and the accreditation and scope of the body that issued it can be confirmed on ASCB's verify page.
Common questions
When was ISO 14001:2026 published?
In April 2026, as the fourth edition of the standard, replacing ISO 14001:2015 and incorporating the 2024 amendment on climate change.
How long do certified organizations have to transition?
For certificates issued by ASCB-accredited certification bodies, the transition deadline is April 30, 2029. The timing and detail for a particular certificate come from the certification body that issued it.
Is a certificate to ISO 14001:2015 still valid?
Yes. Certification against the 2015 edition may continue for bodies not yet transitioned until April 30, 2029, and a 2015 certificate remains current during the transition period. After that date only the 2026 edition applies.
Does ISO 14001:2026 add new climate change requirements?
Not for an organization that already applied the 2024 amendment. The 2026 edition carries that requirement into the standard itself, with climate change named among the environmental conditions an organization considers when it determines its context.
Is ISO 14001:2026 a rewrite of the standard?
No. Clauses 4 to 10 keep their structure, and most requirements are substantially as they were. The changes are concentrated in the areas summarized above.
Where can the changes be read in full?
The
ISO 14001 overview in the Standards Library sets out each change against the clause text of both editions. The standard itself is available from
