The new ISO 14001:2026 is coming. The final draft was released in January 2026 and the standard is expected to be released in April. You have three years to switch - until May 2029. The changes are clear, not a complete turnaround. However, biodiversity, chain responsibility and climate are now stated much more clearly. In this article you can read what exactly is changing and what you can do now.
New to ISO 14001? First read our complete guide to ISO 14001 certification for the basics.
What exactly is changing?
ISO 14001:2026 is an update, not a complete revision. Your existing environmental system remains intact. There are a few specific additions.
New: Change management
There is a completely new clause (6.3) about controlling changes. Do you want to change something about your environmental system? Then you have to approach this in a planned manner. Consider a new production line, a move or a different waste policy.
Many companies already do this. But now you also have to demonstrate it. Record what you change, why, and how you assess the consequences. ISO 9001 and ISO 45001 already had this requirement. It is new for ISO 14001.
Wider context: biodiversity, pollution, resources
From now on, you must include more themes in your context analysis (clause 4.1). Climate change has been on the agenda since the 2024 amendment. Now added to this are biodiversity and ecosystem health, pollution levels and availability of natural resources.
Sounds tough, but it's not that bad. You just need to think about whether these themes are relevant to your business. A construction company near a nature reserve? Then biodiversity is relevant. An office in the city centre? Probably less. Record your decision and you're done.
More control over your chain
Clause 8.1 goes further than before. Previously, you only had to manage outsourced processes. Now it concerns all externally provided processes, products and services. Your environmental responsibility therefore extends deeper into your value chain.
Practical: include suppliers and purchased services in your environmental management. Set requirements, make agreements and check whether they are adhered to.
Life cycle and leadership tightened
The life cycle perspective is given more emphasis. You not only look at your own processes, but also at what happens before and after your link in the chain. Consider raw materials, transport and waste phase.
In addition, the role of top management is becoming more personal. Management now bears non-delegable responsibility for environmental performance. Finally, clause 6.1 is split: 6.1.4 for identifying risks and opportunities, 6.1.5 for the associated action plans.
Terminology updates
A number of terms change. It makes little difference in terms of content, but you will have to adjust your documentation.
Compliance Obligations
Compliance obligations
Maintain documented information
Available as documented information
Outsourced processes
Externally provided processes, products or services
No reason to panic. Go through your documents and replace the old terms. That's it.
The timeline: when should you take action?
With every new ISO standard you get a transition period. Based on what we know now, the schedule looks like this:
January 2026
FDIS (final draft) released
April 2026
ISO 14001:2026 to be published (expected)
2027
First certificates based on the 2026 standard possible (expected)
May 2029
ISO 14001:2015 is withdrawn, all certificates must have been transferred
Note: this is an expectation. Exact dates will be confirmed upon publication. Some certification bodies indicate that the transition period may be shorter than three years. The formal IAF Mandatory Document on this is not yet final.
Good to know. Your current certificate remains valid until the transition period ends. You do not have to take action immediately as soon as the new standard appears.
What does this mean for you?
If you already have ISO 14001:2015
Your certificate remains valid. Your certification body will ensure that you gradually switch to the 2026 version during the regular audits. This usually happens during your recertification (every three years).
What you can do now:
- Check whether biodiversity and ecosystem health are relevant to your company
- Check whether you are recording changes in your environmental system in a structured manner (clause 6.3)
- Check whether you include suppliers and purchased services in your environmental management
None of this is urgent. But if you tackle this now, you will avoid stress later.
If you don't have ISO 14001 yet
Certification is still allowed based on ISO 14001:2015. This will remain possible until 2029. If you start in 2026, you will simply receive a valid certificate.
Certification bodies will guide you through the switch as soon as necessary. You don't have to wait for the new version if you want to start now.
If you doubt your current certification body
A change in standards is a good time to evaluate whether you are satisfied. Things that will become important in 2026:
- Does your certification body proactively guide you through the transition?
- Do you receive concrete tips, or is a checklist ticked off?
- Is the collaboration pleasant?
You can always switch, even during your certification cycle. Your current certificate remains valid, and the new certification body will take over your cycle.
How does this compare to ISO 9001:2026?
ISO 14001 is a few months ahead of ISO 9001. The new ISO 14001 will be released in April 2026, the revised ISO 9001 will follow in September 2026.
In terms of impact, the changes in ISO 14001 are moderate, while ISO 9001 sees more extensive changes. Both standards follow the same Harmonized Structure - if you have both certificates, integration will become easier.
The new clause 6.3 (change management) aligns ISO 14001 with ISO 9001 and ISO 45001. Curious about what changes with ISO 9001? Read the article ISO 9001:2026: what's changing?.
Finally
The final text of ISO 14001:2026 will be published in April 2026. Until then, details can still be adjusted. Keep this in mind if you are making preparations now.
