ISO climate change amendment: what the 2024 changes mean for ISO 14001 and other management systems

What did the ISO climate change amendment add?

The ISO climate change amendment added exactly two statements to the context clauses of ISO's management system standards. Clause 4.1, which asks an organisation to understand the internal and external issues that affect its system, gained a sentence requiring the organisation to determine whether climate change is a relevant issue. Clause 4.2, on interested parties, gained a note: "Relevant interested parties can have requirements related to climate change."

For environmental management the change was issued as ISO 14001:2015/Amd 1:2024, "Amendment 1: Climate action changes", a one-page document from ISO/TC 207/SC 1 published in February 2024. The same wording reached other certifiable standards at the same moment, among them ISO 9001:2015, ISO/IEC 27001:2022, ISO 45001:2018 and ISO 50001:2018, each through its own Amendment 1:2024.

Only the first statement is a requirement. The second is a note, and notes in ISO standards explain or illustrate; they do not add obligations of their own. It tells you where to look: customers, regulators, lenders and parent companies may already expect something of you on climate.

Why ISO changed its management system standards

The amendments trace back to the London Declaration of 24 September 2021, in which ISO committed to work with its members and partners so that its standards and publications help deliver the Paris Agreement, the United Nations Sustainable Development Goals and the United Nations Call for Action on Adaptation and Resilience. ISO also committed to bring climate considerations into new standards and into existing ones as they are revised.

Management system standards share a common core text, the Harmonized Structure, and the same two statements were issued for all of them together. The communiqué states that the two new statements will be incorporated into the new text of the Harmonized Structure, so standards revised since then carry them as part of their own wording rather than as a separate amendment.

What auditors check after the 2024 amendments

No one has published a new audit checklist for the amendment. What certification auditors look for comes from three official texts, and none of them goes beyond the two added sentences. The table sets out what each says.

Read together, the texts ask whether the question was asked, whether the answer fits your site and the law that applies to it, and whether a positive answer flows into planning. The APG paper is equally clear on the other side: the amendment does not require climate change initiatives unless climate change has been identified as a relevant issue. For an environmental system the practical questions an auditor asks by clause are covered in our ISO 14001 audit questions guide.

How to decide whether climate change is relevant to your EMS

The decision belongs in the context review you already run for clause 4.1, not in a separate climate project. A workable method has four steps.

1. Look at climate change both ways

Ask how your activities contribute to climate change, through fuel, electricity, refrigerants, transport and materials, and how climate change can affect your ability to achieve the intended outcomes of the EMS: heat, flooding, storms, water stress and the regulatory response to all of them.

2. Check what interested parties expect

List the climate-related requirements that actually reach you: a customer's supplier questionnaire, a lender's disclosure request, a permit condition, a parent company's target. Decide which of them you adopt as compliance obligations. The note in 4.2 is a prompt to look, not a rule that every expectation binds you.

3. Reach a decision and give the reason

The answer is yes, no, or yes for part of the scope. The amendment itself adds no requirement for documented information, but an auditor can only accept a decision you can show, so most organisations record it in the minutes of the context review or the management review, with the reasoning in two or three sentences.

4. Carry a yes into planning

If climate change is relevant, it feeds the risks and opportunities of clause 6.1 and may shape objectives, operational controls and emergency preparedness. How climate-related activities enter your significance scoring is explained in our guide to environmental aspects and impacts.

Two examples show how differently the answer can land. A cold-chain logistics company in the UAE finds climate highly relevant: refrigerant leaks and fleet fuel are significant aspects, extreme heat threatens its operations and customers ask for emissions data. A textile dyeing unit in India discovers that monsoon flooding is the real issue for its effluent treatment plant and adds it to its emergency scenarios. Both decisions can satisfy an auditor because each rests on the facts of the site.

Where ISO 14001:2026 takes the climate requirement

ISO 14001:2026, published on 15 April 2026, replaced both the 2015 edition and its 2024 amendment. The new edition keeps the climate change requirement in its context clause and places it alongside other environmental conditions such as natural resources, pollution levels and biodiversity. A determination made for the amendment is therefore the starting point for the new edition, not a document to discard. Transition dates, the other changes and the route for moving a certificate are covered in ISO 14001:2026: what changes and how to transition.

Mistakes organisations make with the climate amendment

• Treating it as a carbon reporting mandate. The amendment asks for a determination, not an inventory. If you choose to quantify emissions, standards such as ISO 14064-1 exist for that purpose; our comparison of ISO 14064-1 and ISO 14068-1 explains the options.
• A one-line "not relevant" with no reasoning. An auditor has nothing to test.
• A climate section bolted onto the manual. The decision should sit in the context review, where issues are already determined, and flow into planning from there.
• Considering only emissions. Physical effects of climate on the site, such as flooding, heat and water scarcity, are often the more material issue for operations and emergency plans.
• Deciding once and never again. Climate expectations move quickly, so the decision belongs on the management review agenda.
