What the amendment is and since when it's in force

On 23 February 2024, ISO 9001:2015/Amd 1:2024 was published, titled "Climate action changes", developed by committee ISO/TC 176/SC 2. It's worth establishing the nature of the document from the outset: this is an amendment to the 2015 edition, not a new edition of the standard. The structure, requirements and numbering of ISO 9001:2015 remain the same; what the amendment does is insert two small additions into chapter 4.

The second key fact is how it applies. The IAF (International Accreditation Forum) and ISO itself stated that, given the nature of the amendment, it does not require a specific transition programme. Unlike an edition change, where there's a period of several years to migrate certificates, here the amendment has been part of the auditable requirements since its publication. In practice, this means any audit carried out from 2024 onwards can and must already assess this point. If your organisation is certified, you don't need a formal transition: the change is built into your normal cycle of surveillance and recertification audits.

I don't want to cause unnecessary alarm. We're talking about a very contained addition, not a deep revision. The thorough revision will come with the new edition of ISO 9001 expected in 2026, which is a separate matter of much wider scope. This article deals only with what's already confirmed and in force.

What exactly changes: clause 4.1 and clause 4.2

The amendment adds exactly two provisions, incorporated into the Harmonised Structure shared by management system standards (Annex SL, Appendix 2). It's important to tell them apart precisely, because they carry very different legal-technical weight.

Clause 4.1: an auditable requirement

Clause 4.1 deals with the organisation's understanding of itself and its context. The amendment adds a sentence with an obligation verb ("shall"). The official text reads: "The organization shall determine whether climate change is a relevant issue." That's the governing wording; any other-language rendering (for example an official Spanish AENOR/UNE translation) should be read as informative, with the English original taking precedence.

The use of the verb "shall" is what turns this sentence into a requirement. A requirement is enforceable and auditable: an auditor can ask you for evidence that you've met it, and its absence can generate a nonconformity. This isn't a recommendation or an optional good practice.

Clause 4.2: an informative note

Clause 4.2 deals with the needs and expectations of interested parties. The amendment adds a note, not a requirement. The official text reads: "Relevant interested parties can have requirements related to climate change."

In the grammar of ISO standards, a note is clarifying information that helps interpret the text, but it doesn't create an obligation. The verb here is "can", not "shall". So clause 4.2 doesn't add anything enforceable: it simply reminds you that your customers, regulators, investors or other interested parties might have climate-related expectations worth bearing in mind when you analyse your context.

This distinction isn't an academic nuance. I've seen the amendment interpreted as if it obliged you to open up a full climate chapter in your management system, and that overstates what it says. What's actually on the table are two specific provisions: a requirement in 4.1 and a note in 4.2. Not a comma more.

What it really obliges — and what it doesn't

Let's get to the heart of it, because this is where the misunderstandings pile up. The obligation the amendment introduces is analytical in nature, not a performance obligation. What you're required to do is determine whether climate change is a relevant issue for your quality management system. The auditor will assess how you reached that conclusion, not what climate initiatives you have.

From there, two paths open up, both legitimate:

What the amendment does not do is force you to have climate policies, emission-reduction targets or sustainability initiatives. Those obligations only appear if you yourself identify climate change as relevant and, as a result, decide to manage it. It isn't a carbon footprint standard, it doesn't ask you to calculate Scope 1, 2 or 3 emissions, and it doesn't overlap with standards such as ISO 14064 or ISO 14001. Its scope is strictly that of context analysis.

The following table summarises the line between what's required and what isn't:

What the amendment requiresWhat it does NOT require
Determining whether climate change is a relevant issue (clause 4.1, requirement).Having a climate policy or strategy per se.
Leaving reasoned evidence of that determination, whatever the outcome.Setting emission-reduction targets.
If it is relevant, integrating it among your context issues and treating it as such.Calculating your carbon footprint or Scope 1, 2 or 3 emissions.
Considering the clause 4.2 note when analysing interested parties (no new obligation).Meeting third parties' climate requirements you haven't identified as applicable.

How it's demonstrated in an audit

The practical question I get from almost every client is: "what do I have to show the auditor?". The answer is simple, which is exactly why it's worth not overcomplicating it. What gets audited is the relevance determination — that is, evidence that you've done the exercise of thinking through whether climate affects your management system.

In most organisations, the natural place to document it is the context analysis you already maintain for clause 4.1: the matrix of internal and external issues, the SWOT analysis, the management review minutes, or whatever procedure captures your context. You don't need to create a new document or a special record. It's enough for climate change to be explicitly addressed, with a reasoned conclusion.

My recommendation, from the perspective of someone who's been through many audits, is to leave a record of three elements:

This point fits naturally into your internal audit: reviewing it before the certification audit is the most effective way to avoid surprises. If you manage several standards at once under an integrated management system, the logical approach is to resolve the relevance determination once, in the shared context analysis, and have it serve all the affected standards.

Which standards it affects

Because the amendment was applied to the shared Harmonised Structure (Annex SL), it isn't limited to ISO 9001. It affects around 31 so-called "Type A" management system standards (the certifiable ones), which share the same chapter 4 wording. Among the best known are:

The practical consequence for anyone with an integrated system is a good one: the determination exercise is essentially the same across all of them, because the added sentence is identical. You don't have to repeat the analysis standard by standard; you do it once, in your organisation's context, and project it across every standard you certify to.

Common mistakes and myths

I'll finish with the misunderstandings that circulate most, because correcting them in time saves work and headaches:

Conclusion

The 2024 climate change amendment is a small change in extent but an important one in intent: it makes sure no certified organisation can ignore climate without having thought about it. The key is understanding it precisely — no less, no more. There's a real requirement in clause 4.1 (determine relevance) and a note in clause 4.2 (no obligation). Everything else — policies, targets or emissions calculations — only comes into play if you identify climate as relevant to your activity.

If you'd like to review how this point is handled in your context analysis before your next audit, or you need to integrate the relevance determination into a system with several standards, I can help with a proportionate approach that won't overload your system, through my ISO consulting. Let's talk about your case in an initial consultation and get it resolved properly.

Frequently asked questions

Is the ISO 9001 climate change amendment already in force?
Yes. ISO 9001:2015/Amd 1:2024 was published on 23 February 2024 and applies immediately. The IAF confirmed it doesn't require a specific transition programme, so it's been part of the auditable requirements since publication and is built into ordinary surveillance and recertification audits.
What exactly does the amendment add?
It adds exactly two provisions to chapter 4. Clause 4.1 introduces a requirement ("the organization shall determine whether climate change is a relevant issue") and clause 4.2 adds an informative note that interested parties can have requirements related to climate change. 4.1 obliges; 4.2 doesn't.
Am I required to have a climate policy or measure my carbon footprint?
No. The amendment isn't a carbon footprint standard and doesn't require you to calculate emissions. It only requires you to determine whether climate change is a relevant issue for your management system. Climate policies, targets or initiatives would only be needed if you conclude that climate is indeed relevant to your activity.
How do I demonstrate compliance in an audit?
By leaving reasoned evidence of the relevance determination in your clause 4.1 context analysis (matrix of internal and external issues, SWOT, management review, etc.). It's worth reflecting that climate change has been considered, the conclusion reached, and a brief justification consistent with your activity. There's no need to create a new document.
Which standards does it affect besides ISO 9001?
Since it was applied to the shared Harmonised Structure (Annex SL), it affects around 31 certifiable management system standards, including ISO 14001:2015, ISO 45001:2018, ISO/IEC 27001:2022, ISO 22000:2018 and ISO 22301:2019. The added sentence is identical across all of them, so in an integrated system the analysis is done just once.
