ISO published the sixth edition of ISO 9001, its quality management systems standard, on September 16, 2026. ISO 9001:2026 replaces ISO 9001:2015 and its 2024 climate change amendment, which are now withdrawn. Digitally enhanced content for the new edition becomes available October 1, 2026.
ISO 9001 is used by more than 1 million certified organizations worldwide, across every sector and organization size. The revision was developed by ISO/TC 176/SC 2, the subcommittee responsible for quality systems standards, and runs 36 pages.
What Changed From the 2015 Edition
ISO 9001:2026 keeps the same core requirements and process approach as the 2015 edition, but adds or reworks several areas:
- Harmonized Structure. The standard moves to the Harmonized Structure now used across ISO management system standards, which is meant to make it easier to run ISO 9001 alongside standards such as ISO 14001 (environment) or ISO 45001 (occupational health and safety).
- Leadership and quality culture (Clause 5). Top management's role now covers building a quality culture and ethical behavior, not only assigning responsibilities. The quality policy must connect more explicitly to the organization's context and strategic direction.
- Risk and opportunity (Clause 6). Risks and opportunities move into separate, clearer subclauses instead of being handled together, with expanded guidance on managing changes to the quality management system.
- Awareness (Clause 7). New requirements call for people to understand quality culture and ethical behavior, in addition to their own role in the system.
- Terms and definitions (Clause 3). The standard adds its own quality-management-specific terms, reducing how often readers need to cross-reference the separate ISO 9000 vocabulary standard.
- New Annex A. A new annex explains the intent behind requirements and clarifies key concepts, to support more consistent interpretation between auditors and organizations.
The climate change considerations added to ISO 9001:2015 by its 2024 amendment carry forward into the new edition.
Why ISO Revised the Standard Now
ISO says organizations are now operating in a different environment than when the 2015 edition was written, citing digital transformation, more interconnected supply chains, evolving stakeholder expectations, and pressure for speed, resilience, and transparency. Sam Somerville, chair of ISO/TC 176/SC 2, described the result as "a standard that reflects the different realities organizations face today."
ISO Secretary-General Sergio Mujica framed the publication as evidence the standard can evolve while keeping the qualities that made it the most widely adopted management system standard in the world. BSI chief executive Susan Taylor Martin, quoted in the same release, said ISO 9001 remains the standard most organizations reach for when they need a common framework for quality.
Transition Timeline
- September 16, 2026: ISO 9001:2026 published, superseding ISO 9001:2015 and its 2024 amendment.
- October 1, 2026: Digitally enhanced content for the new edition becomes available.
- March 31, 2027: Accreditation bodies must be ready to assess against ISO 9001:2026.
- June 30, 2027: Certification bodies submit their transition declarations.
- September 30, 2027: Accreditation bodies complete their transition decisions.
- March 31, 2028: New certifications can only be issued against ISO 9001:2026, not the 2015 edition.
- September 30, 2029: Final deadline for organizations already certified to ISO 9001:2015 to complete their transition.
This schedule is set by Global Accreditation Cooperation Incorporated (Global ACI), the body that now oversees accredited certification worldwide. Global ACI was formed on January 1, 2026, when the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC) ceased separate operations and merged. Existing IAF and ILAC accreditation marks stay valid through the changeover, so certification bodies and their accreditation stay recognized while the two organizations combine.
Organizations do not need to restart certification from scratch. Certification bodies keep auditing against ISO 9001:2015 until the transition windows above close, and each organization completes its own move during a scheduled surveillance or recertification audit, or through a separate transition audit, arranged with its certification body.
What This Means for EHS Teams
ISO 9001 is a quality management standard, not an EHS one, so this revision doesn't change anyone's safety or environmental obligations directly. But it still tends to land on an EHS or QHSE manager's desk, because quality, environmental, and safety management systems are frequently run together.
That overlap is built into the standard now more than before. ISO 9001:2026 adopts the Harmonized Structure already used by ISO 14001 (environmental management) and ISO 45001 (occupational health and safety), the same structure most integrated management systems are built on. Organizations that run all three together will plan this transition alongside their existing EMS and OHSMS work, often through the same management review meetings and the same internal audit program.
Two practical points follow from that overlap. First, document control: ISO 9001's requirements around documented information and change management run on the same discipline EHS teams already apply to SDSs, safety procedures, and audit records, so a revised quality manual is a reasonable moment to check that document control practices stay consistent across all the management systems a site maintains. Second, audit scheduling: where a certification body runs combined audits across 9001, 14001, and 45001, the transition dates above (through September 30, 2029) will shape when those combined audits happen, not just the quality-specific ones.
Quality certification also shows up in supplier qualification and procurement paperwork alongside chemical and safety compliance documentation, so EHS teams that handle supplier questionnaires may see this revision referenced there too. For most sites, the practical next step is the same one raised earlier: ask the certification body handling the 14001 or 45001 audit whether the ISO 9001:2026 transition will be folded into that same visit.
