4.2ISO 9001:2026

Understanding the needs and expectations of interested parties

Changed in ISO 9001:2026

Same, with explicit recognition that parties can have climate-related requirements (in force via the 2024 amendment) — plus one new determination: which of the interested-party requirements your QMS will address.

Checked against the published text on 27 September 2026.

Plain-language summary

The mechanics carry over from 2015: determine the interested parties relevant to the QMS and their relevant requirements. The 2026 text (in force since the 2024 amendment) adds a note-level nudge with practical teeth: interested parties can have climate-related requirements, and your register is expected to show they were considered. Customers asking for emissions data with quotations, insurers and lenders imposing site conditions, and regulators tightening energy or reporting rules are the everyday forms this takes. The published text also adds one small new determination: for each interested-party requirement, which of them your QMS will actually address — so the register needs a column, not just a list.

What the clause is really asking

Whether you have looked at your actual customers, regulators, financiers, employees and neighbours and asked which of them now carry climate-linked expectations of you — and captured the ones that are real requirements rather than sentiments.

What auditors look for

A scan of the interested-parties register against the auditor's knowledge of your industry. If your biggest customer publishes supplier sustainability requirements and your register shows nothing climate-related against that customer, expect the question. Consistency between 4.1 and 4.2 conclusions is also checked — 'climate relevant' in context but absent from every interested party (or vice versa) reads as a paper exercise.

Typical evidence

Interested-parties register (FM-015-style) reviewed within the cycle, with climate-related requirements captured where they genuinely exist — customer sustainability clauses, regulatory reporting duties, insurer conditions.

How to comply — recommendations

Walk the register once: for each party, is there a climate-linked requirement that is actually theirs (contractual, regulatory, financial)? Add the real ones with a source reference. Keep the register review dated and align its conclusions with the 4.1 context analysis.

Common nonconformities

Register untouched since certification; climate expectations noted in context (4.1) but no corresponding party requirement (or vice versa); customer sustainability requirements sitting in contracts but absent from the register.
