This guide covers the wording added to Clauses 4.1 and 4.2, how to decide relevance, which records to update, and what auditors may expect. It is written for U.S. organizations implementing or maintaining ISO 9001:2015. Status note: ISO's catalogue now lists the 2015 amendment as withdrawn and ISO 9001:2026 as published, so confirm what applies to your audit cycle with your certification body and official ISO and IAF sources.
Key Takeaways
- The amendment touches Clauses 4.1 and 4.2 only.
- Decide whether climate change is relevant; emissions reporting, carbon targets, and ISO 14001 are not automatic.
- Relevant issues flow through existing QMS processes, not a separate climate program.
- Keep documented evidence of your decision, including a reasoned "not relevant" conclusion.
What the ISO 9001 Climate Change Amendment Changes
ISO published ISO 9001:2015/Amd 1:2024 on February 23, 2024. It adds two small pieces of text.
- Clause 4.1: "The organization shall determine whether climate change is a relevant issue."
- Clause 4.2: "NOTE: Relevant interested parties can have requirements related to climate change."
What the wording means
Clause 4.1 now names climate change as an external issue to consider alongside the others that could affect your QMS's intended results.
The 4.2 addition is a note, not another "shall." It prompts you to review stakeholder requirements. It does not oblige you to accept every climate-related request.
Applicability and timing
The IAF/ISO joint communiqué, dated February 22, 2024, says the overall intent of 4.1 and 4.2 is unchanged. ANAB's Heads Up 527 (March 4, 2024) covers certified organizations, including applicants, and states the change is effective from publication with no transition period.
IAF and ANAB indicate no revised certificate is issued solely for the amendment, and no amendment-specific special audit is specified. Consideration is assessed during regular audits. Verify details with your certification body.
Links to existing clauses
These clauses were not amended, but climate-change assessment connects to them:
- 4.3 (scope): scope reflects 4.1 issues and 4.2 requirements
- 6.1: relevant issues enter risk and opportunity actions
- 6.2: objectives where treatment calls for them
- 9.3: management review inputs include changes in external issues
- 10.3: continual improvement, with no added climate-project mandate
What Climate Change Relevance Means for an ISO 9001 QMS
The ISO 9001 Auditing Practices Group (APG) guidance on climate says relevance depends on size, sector, products and services, supply-chain position, geography, and QMS scope. It can range from none to extremely relevant.
Direct operations
Ask whether climate-related conditions could affect your ability to deliver conforming products or services:
- Storm, flood, or fire interruptions at facilities
- Energy availability and equipment performance
- Transportation disruptions
- Emergency preparedness and business continuity gaps
The scale is real. NOAA counted 27 U.S. billion-dollar weather and climate disasters in 2024, totaling roughly $182.7B, per its 2024 disaster review. That is historical context, not an ISO relevance threshold, and the total is not attributable solely to climate change.
Supply chain and interested parties
Indirect exposure often matters more:
- Supplier availability and raw-material shortages
- Logistics reliability and subcontractor continuity
- Changing customer or regulatory requirements
Review customers, regulators, suppliers, employees, owners, insurers, and contractual partners. Separate binding requirements, such as statutes and contract clauses, from general expectations. Binding ones must be met. Expectations get weighed.
Hypothetical examples
These are illustrations, not case studies.
- Small professional-services firm: remote-capable staff and no physical supply chain. Likely concludes "not relevant," with a documented rationale, and revisits it annually.
- Manufacturer with dispersed suppliers: a single-source resin supplier in a flood-prone area. Likely relevant, so it feeds supplier evaluation and contingency planning.
- Multisite organization: one coastal plant faces storm exposure while others do not. Relevance differs by site, so records should too.
How to Assess and Integrate Climate Change into the QMS
Don't build a disconnected climate process. Start from what you already have:
- Context review and interested-party register
- Legal and regulatory evaluation
- Customer requirements and supplier reviews
- Business-continuity plans and site risk assessments
A practical relevance assessment
- Identify potential climate-related issues that could touch products, processes, or the supply chain
- Evaluate whether each could affect intended QMS results
- Record who participated and what information they reviewed
- Document the decision and rationale so auditors can follow your reasoning
A "not relevant" conclusion can be acceptable. IAF expects the certification body to assess the effectiveness of your determination process. So make it specific, evidence-based, within QMS scope, and reviewed when conditions change.
If climate change is relevant
Work it into existing mechanisms:
- Risk and opportunity processes
- Quality objectives, where appropriate
- Supplier controls and operational planning
- Contingency arrangements and change management
Records to review
Check these and update only what the assessment affects:
- Context-of-the-organization procedure
- Interested-party register and risk register
- Quality objectives
- Supplier evaluation forms
- Business-continuity records
- Management-review inputs and internal-audit checklists
Nothing here calls for a wholesale QMS rewrite. ISO allows flexibility in the form and extent of documented information, and the amendments do not prescribe a template or climate register.
Verify the response
Use internal audits, management review, monitoring of external issues, and a check on whether actions produced the intended results.
Synergistic Systems helps organizations map climate-related considerations into existing modular documentation and training systems, so implementation avoids duplication and reinvention.
What Auditors May Expect to See
Auditors will look for evidence that you considered climate change in your organizational context and whether interested parties have climate-related requirements. The International Accreditation Forum (IAF) states that a suitable finding should be raised if you cannot demonstrate that consideration. Confirm current audit practice with your certification body.
Useful evidence includes:
- Completed context review
- Documented relevance decision
- Interested-party evaluation
- Risk or opportunity records
- Management-review minutes
- Supplier assessments
- Revised objectives and evidence of implemented actions, where relevance was found
Auditors are expected to stay objective and neutral. Their personal views on climate do not factor into the audit. If you make climate-related claims about products or services, you must show you can meet them.
Multisite organizations
Use a common assessment method centrally, and let each location document its own issues, processes, suppliers, and operating conditions. Keep central and local records consistent. Gaps between them are easy for an auditor to spot.
What the Amendment Does Not Require
The amendment text doesn't prescribe any of the following:
- A separate ISO 14001 system
- A greenhouse-gas inventory
- Emissions targets or carbon offsets
- An environmental policy or climate action plan
The APG states that the amendment "does not require an organization to have climate change initiatives unless it has been identified as a relevant issue to achieve the intended results of the QMS."
Those measures can still arise from your assessment, legal obligations, customer requirements, or objectives you choose. "Not prescribed" is not a blanket exemption from applicable legislation or contracts.
Two opposite mistakes show up in practice:
- Writing "not relevant" with no reasoned assessment behind it
- Adding elaborate climate controls with no link to your QMS
Keep the response proportionate, evidence-based, and periodically reviewed. For certificates and audits, rely on current IAF guidance and your certification body.
Frequently Asked Questions
Which clause in ISO 9001:2015 deals with leadership?
Clause 5, especially 5.1 (Leadership and commitment). Leadership is not one of the clauses directly changed by the climate amendment.
What is clause 4.3 in ISO 9001?
Clause 4.3 covers determining the scope of the QMS. Climate-related issues or interested-party requirements may influence scope, but they don't automatically require a scope change.
What is clause 7.2 in ISO 9001?
Clause 7.2 covers competence. Climate-related training makes sense only if your assessment identifies relevant responsibilities, controls, or competence needs.
Do I need a separate climate change management system for ISO 9001?
No. Relevant issues should generally be integrated into existing QMS processes in a proportionate way.
Do I need a new ISO 9001 certificate because of the climate change amendment?
IAF and ANAB indicate no revised certificate is issued solely for the amendment. Confirm with your certification body. The key task is documenting your relevance assessment and addressing what it finds.
