ISO 14001:2026 transition readiness checklist
The clause-by-clause checklist we use on site, free. If several answers come back 'not sure', that is what a gap analysis is for.
For the dates and what the revision adds, see the ISO 14001:2026 transition page.
For manufacturers holding ISO 14001:2015. Under the UKAS transition plan, certification bodies stop all new certifications to the 2015 version by 31 October 2027, and every certified organisation must have transitioned to the 2026 version by 30 April 2029. Work back from your own next audit date, and treat your certification body's notice as the authority for your certificate. This page maps the revised requirements against what a certification body auditor will ask to see, so the gaps are found before the transition audit rather than during it.
For a strong system, most of the changes are subtle. Subtle is exactly what gets missed. Work through it honestly: every "No" is a piece of work, and every "Not sure" is a piece of work you haven't found yet.
1. Externally provided processes, products and services (clause 8.1)
The 2015 wording covered "outsourced processes." The 2026 wording covers "externally provided process(es), products or services that are relevant to the intended outcomes of the EMS." It reaches suppliers, contractors and service providers, and requires you to determine which are in scope.
| Check | Yes / No / Not sure |
|---|---|
| We have determined which externally provided processes, products and services affect our EMS outcomes | |
| We can show the reasoning for what is excluded, not only what is included | |
| It covers raw material suppliers, not only contracted-out functions such as waste and transport | |
| Where we toll-manufacture for a customer, or a toll manufacturer produces for us, the environmental responsibilities are written into the arrangement | |
| We can show evidence of control or influence proportionate to each provision in scope |
The auditor will ask: how did you decide which are in; why are these out; what does control look like for the ones that are in?
2. Life cycle perspective and emergency situations (clauses 4.3, 6.1.2, 8.1, 8.2)
The life cycle perspective is now considered when setting the scope of the EMS, for environmental aspects and for operational controls. That means a documented perspective, not a life cycle assessment. Potential emergency situations are now part of determining environmental aspects (6.1.2), linked to emergency preparedness (8.2).
| Check | Yes / No / Not sure |
|---|---|
| Our EMS scope shows that life cycle stages were considered: raw material acquisition, design, production, transport, use, end of life | |
| Our aspects register includes aspects upstream or downstream of production, where we can control or influence them | |
| Our operational controls reflect the stages we can influence, not only what happens inside the fence | |
| Potential emergency situations are identified in our aspects work and carried through to 8.2 preparedness and response | |
| The scope statement has been revisited since 2015 |
The auditor will ask: which life cycle stages did you consider, and where is that recorded? Why does the aspects register stop at the factory gate? Where are emergency situations in it?
3. Planning of changes (new clause 6.3)
This clause did not exist in 2015. Changes that affect or can affect the EMS "shall be carried out in a planned manner", managed so the EMS can still achieve its intended outcomes. You keep the documented information your EMS needs, and you must be able to show that changes were planned.
| Check | Yes / No / Not sure |
|---|---|
| We have a way of planning changes that covers internal and external sources: restructuring, new legal obligations, customer requirements, lessons from incidents | |
| It asks an environmental question, not only quality and performance questions | |
| A raw material substitution at the same specification is treated as a change | |
| A change of supplier is treated as a change | |
| A revision to a work instruction or procedure is treated as a change | |
| It considers resources, training and communication for the change | |
| For the last three changes we made, we can show how their environmental implications were considered and who decided |
The auditor will ask: show me a change from the last year. Where were its environmental implications considered, and who decided?
For a formulation business, change is continuous. A record is the only practical way to show it was planned.
4. Environmental conditions (clause 4.1)
When determining context, the requirement now names external environmental conditions such as pollution, availability of natural resources, climate change, biodiversity and ecosystem health. They are examples, not an exhaustive list, but naming each is the simplest evidence that they were considered.
| Check | Yes / No / Not sure |
|---|---|
| Our context analysis names each of the five conditions, plus any others specific to our site | |
| Where a condition is judged not relevant to us, a one-line rationale is recorded | |
| Climate change is considered as a condition affecting the site (heat, water availability, flood risk, raw material supply), not only as an impact we have | |
| Conditions judged relevant are carried through to risks and opportunities |
The auditor will ask: which external environmental conditions affect you? If you've decided biodiversity doesn't apply to a factory, where is that written down?
5. Other changes
| Check | Yes / No / Not sure |
|---|---|
| Risks and opportunities (6.1.4): determined and available as documented information, distinguishable from the aspects register and the compliance obligations register | |
| Internal audit objectives (9.2.2): each internal audit has a stated objective, not only a scope and criteria | |
| Leadership (5.1): top management can show engagement in environmental performance, supports other relevant roles and promotes the culture, with evidence in minutes and decisions | |
| Management review (9.3): structured as general, inputs and results; top management takes part and is accountable; results are documented | |
| Annex A: we have read the guidance alongside each clause, including on chemicals management |
Reading the result
Every box Yes: book the transition audit; you're ready.
One or two No or Not sure: an afternoon with the new text and Annex A closes most of them.
Several No in section 3: you need a way of planning changes, not just an edited document. Start there.
Several Not sure across sections: an independent gap analysis against the 2026 text will find them faster than you will, and finding them before the auditor does is the entire point.
