ISO 9001:2015 vs ISO 9001:2026: What Is the Difference?
Quick Answer: ISO 9001:2026 is an updated edition of ISO 9001:2015, not a new standard. It keeps the same quality management framework and adds a stronger focus on quality culture, ethical behavior, change management, separate treatment of risks and opportunities, and a consolidated improvement clause. ISO 9001:2015 certificates stay valid until 30 September 2029.
ISO published ISO 9001:2026 on 16 September 2026, so many organizations are asking what has actually changed. This guide explains the differences in plain language and shows what to do next.
What Is ISO 9001:2026?
ISO 9001:2026 is the sixth edition of the international standard for quality management systems (QMS). It replaces ISO 9001:2015 and includes the climate change amendment that was added to the 2015 edition in 2024. The familiar structure remains, so an organization with a working QMS is not starting from zero.
What Are the Main Differences Between ISO 9001:2015 and ISO 9001:2026?
The table below compares the areas that changed. Clause numbers follow the published standard, so always confirm details against the final text.
| Area | ISO 9001:2015 | ISO 9001:2026 |
|---|---|---|
| Leadership (5.1.1) | Top management shows leadership and commitment to the QMS and customer focus | Adds a duty to promote quality culture and ethical behavior |
| Risks and opportunities (6.1) | Handled together in one planning clause | Risks (6.1.2) and opportunities (6.1.3) are addressed separately |
| Planning of changes (6.3) | Basic requirement to plan changes to the QMS | Reinforced requirements to manage changes so the system keeps delivering results |
| Awareness (7.3) | People know the policy, objectives, and their contribution | More emphasis on awareness of quality culture and ethical behavior |
| Continual improvement (10.1) | Covered across clauses 10.1 and 10.3 | Consolidated into clause 10.1, with new guidance in Annex A |
| Terms and structure (3) | Terms refer to ISO 9000 | Also lists the twenty terms of the harmonized structure |
| Climate change | Added by the 2024 amendment | Carried into the standard text, so not a brand new requirement |
| Certificate status | Valid until 30 September 2029 | Current edition since 16 September 2026 |
For most teams, the biggest shift is in leadership. Top management should be ready to explain how it promotes quality culture and ethical behavior, and to show evidence of it.
Is ISO 9001:2026 a Completely New Standard?
No. It is an update built on the 2015 edition. Most requirements stay the same, so your existing procedures, records, and audit routines remain useful. Review them against the changed clauses instead of rebuilding your system.
What Happens to ISO 9001:2015 Certificates?
Global ACI has set a three year transition period. ISO 9001:2015 certificates stop being valid after 30 September 2029, so every certified organization needs a transition audit before that date. Until then, your current certificate stays valid.
What Should Certified Organizations Do Now?
- Get the published standard from ISO or your national standards body and compare clauses 5.1.1, 6.1, 6.3, 7.3, and 10.1 with your system.
- Update your risk and opportunity records so each one is handled separately.
- Brief top management on quality culture and ethical behavior, and record how leaders promote them.
- Ask your certification body when to schedule the transition audit. Many organizations combine it with a surveillance or recertification audit.

What If I Am Applying for the First Time?
Ask your certification body which edition your first audit will be assessed against, because availability of audits to the new edition depends on accreditation. Buyers and tender committees may also name an edition, so check the prequalification documents before you apply. Work you complete on your QMS now carries over to either edition.
FAQ
What is the difference between ISO 9001:2015 and ISO 9001:2026?
ISO 9001:2026 keeps the 2015 framework and adds a leadership duty to promote quality culture and ethical behavior, separate clauses for risks and opportunities, stronger change management, and a consolidated continual improvement clause.
When do I need to move from ISO 9001:2015 to ISO 9001:2026?
You have until 30 September 2029. After that date ISO 9001:2015 certificates are no longer valid, so plan your transition audit with your certification body well before then.
Is ISO 9001:2026 harder to meet than ISO 9001:2015?
Most changes are targeted refinements, so organizations with a mature QMS should find the gaps limited. The effort depends on how well your current system handles leadership, risks, and change.
Are the climate change requirements new in ISO 9001:2026?
No. Climate provisions were added to ISO 9001:2015 through a 2024 amendment and are carried into the 2026 edition.
