Last year, while helping clients apply the climate change amendment to ISO 9001 (Amd 1:2024), the approach I saw most often was one line added to the 4.1 context table: “Climate change is not relevant to our operations.” Nothing else followed.

ISO 9001:2026 closes that door. Going by the FDIS text, the sixth edition is an evolutionary update. The clause structure carries over from 2015 and nobody needs to rewrite their quality manual from scratch. Three changes, though, deserve real attention, because they change what an auditor will ask to see.

1. Climate moves from an amendment into the main text

The 2024 amendment added one sentence to clause 4.1, asking organisations to determine whether climate change is a relevant issue, and a note to 4.2 that interested parties can have climate-related requirements. In the 2026 edition this becomes part of the standard itself.

A genuine assessment is not about the weather. For a manufacturer supplying international projects, the questions are much closer to home:

• Do customers already ask for CO₂ data, reduction targets or low-carbon materials in RFQs and supplier codes?
• Do carbon border mechanisms such as the EU CBAM apply to the products you ship?
• Are you being asked for product carbon footprints to ISO 14067?
• Does any of this affect which products and services you can keep selling, and to whom?

Risks and actions then have to follow from that assessment. If the 6.1 risk register contains nothing climate-related, expect the auditor to go back to 4.1 and ask how that assessment was actually done.

2. Quality culture and ethical behaviour become leadership duties

Clause 5.1 adds promoting quality culture and ethical behaviour to top management's commitments. A new note explains that culture and ethics can be demonstrated through shared values, beliefs, history, attitudes and observed behaviours.

“Observed behaviours” is the phrase that matters. It turns culture from a poster on the wall into something that can be audited. From the client representative side of the table, a supplier's quality culture shows up quickly: an inspector told to sign the ITP hold point and sort out the paperwork later, welding records filled in after the fact, a nonconformity closed without a root cause. Under the 2026 edition, findings like these connect directly to leadership, not only to the shop floor.

Transition guidance from certification bodies also indicates that the awareness requirements are expected to point in the same direction.

3. Smaller edits that make the system harder to fake

• 6.1 is split. Risks and opportunities get separate sub-clauses, each needing its own process to identify them and plan actions. Opportunities are no longer an extra column at the end of the risk table.
• 6.3 asks how a change is verified. Planning a change now includes how its effectiveness will be monitored and evaluated, and how the results will be reviewed.
• 6.2 is more pragmatic. Quality objectives need to be measurable where practicable. That is a reasonable relaxation, not a loophole: objectives still have to be monitored, communicated and updated.

Where quality data and carbon data finally meet

For years the QMS focused on documentation, procedures and continual improvement, while the greenhouse gas inventory sat with a separate team. The two sets of data were never reconciled. Under the 2026 edition, a customer's decarbonisation commitment or a supply chain carbon requirement needs a matching risk assessment and action inside the quality system.

In practice much of the evidence already exists. The data collected for an ISO 14067 product footprint or for CBAM embedded emissions, such as material sources, process energy and production volumes, is largely what a credible 4.1 and 6.1 climate assessment needs. Collecting it twice, in two formats, for two teams, is where companies lose time and consistency.

Timeline and a practical order of work

Certification bodies have to be accredited to the new edition before they can audit against it, so there is no prize for being first. Leaving everything until 2029 is the more common mistake. A sensible order of work:

1. Run a clause-by-clause gap analysis between your current system and the 2026 text.
2. Redo the 4.1 and 4.2 analysis with real inputs: customer requirements, export markets, product carbon data.
3. Split the risk register into risks and opportunities, and link climate items to actions.
4. Update leadership and awareness training to cover quality culture and ethical behaviour.
5. Complete an internal audit and management review on the new basis before the transition audit, ideally lined up with your surveillance cycle.

Most companies will pass the transition audit. The ones that get real value from it are those that stop treating the climate row as a formality and let it change what they actually measure.
