The three most widely used ISO management system standards are being revised together. ISO 14001:2026 and ISO 9001:2026 are now published, and ISO 45001 has passed its Draft International Standard (DIS) ballot, with the new edition expected in 2027.

The common thread is the 2024 climate action amendment, which is now built permanently into each standard. Each revision also puts more weight on supply chains, resilience, organisational culture and the wellbeing of people at work.

This guide sets out the timelines, the main changes in each standard, how to handle the transition if you run an integrated management system (IMS), and what certified organisations should do now.

Key takeaways

  • ISO 14001:2026 was published on 15 April 2026 and ISO 9001:2026 on 16 September 2026.
  • Certified organisations get a transition period of about three years for each standard.
  • ISO 45001:2027 is still a draft. Its main themes are wellbeing and psychosocial risk, hybrid work, contractors and new technology.
  • If you run an IMS, plan one integrated transition rather than three separate projects.

Final transition deadlines are set through IAF and applied by each certification body. Confirm the exact dates for your certificate with your certification body.

ISO 14001:2026 (Environmental management)

The 2026 edition moves organisations from basic compliance towards environmental outcomes they can show and measure.

  • Climate change in context and planning: The 2024 climate amendment is now part of the standard. Climate change must be considered when you set your context, your aspects and impacts, and your risks and opportunities.
  • Wider environmental conditions: More attention to natural resources, pollution and biodiversity, both as impacts you cause and as conditions that affect your operations.
  • Life-cycle and value-chain thinking: Stronger expectations to control and influence environmental performance across suppliers, contractors and externally provided processes.
  • Planned management of change: A dedicated requirement to plan changes to the environmental management system and reassess their environmental effects.
  • Clearer structure: The guidance on risks and opportunities is reorganised, the improvement clauses are consolidated, and the guidance annex is updated.

ISO 9001:2026 (Quality management)

The core process approach is unchanged, but the 2026 edition adds expectations aimed at long-term business resilience and the way people behave inside the system.

  • Quality culture and ethical behaviour: Top management must promote a culture of quality and ethical behaviour, and auditors will look for evidence of it, not only a policy statement.
  • Climate change in context: You must decide whether climate change is a relevant issue for your organisation, for example if it could affect your supply, operations or the delivery of your products and services.
  • Risks and opportunities treated separately: The requirements now separate how you address risks from how you pursue opportunities, which makes planning clearer and easier to audit.
  • Resilience: More emphasis on preparing the system for disruption such as supply chain failure or sudden changes in the market.

ISO 45001:2027 (Occupational health & safety)

The revision has completed its Draft International Standard ballot (June to September 2026), and publication is expected in 2027. The final text may still change, but the direction is clear and reflects how work has changed since 2018.

  • Wellbeing and psychosocial risk: Broader treatment of mental health and wellbeing, including stress, burnout and workplace behaviour, in line with ISO 45003.
  • Remote, hybrid and digital work: OH&S arrangements that cover people working from home, on the move or in flexible teams.
  • Contractors and external providers: Stronger control of outsourced activities and supply-chain OH&S risks.
  • New technology: Assessing the risks of new and changing technology at work, such as automation and collaborative equipment.
  • Climate and a diverse workforce: Climate-related OH&S risks such as extreme heat, and recognition that different groups of workers can face different risks.

Managing the transition with an integrated management system (IMS)

If you combine quality, environment and health & safety in one system, these revisions are a chance to simplify compliance instead of repeating the same work three times.

  • One climate risk assessment: Run a single, consolidated climate review that feeds the context requirements (Clause 4) of all three standards.
  • Harmonised documentation: All three standards follow ISO's Harmonized Structure (Annex SL), so change management, resilience and context procedures can sit in one IMS manual.
  • Combined internal audits: Train your internal auditors on all three revisions together and run one readiness audit, which saves time on the shop floor.
  • Move records off spreadsheets: A transition is a good time to centralise CAPA, incident investigations and audit findings. A platform such as HSEFQ keeps evidence for all three standards in one dashboard.

What certified organisations should do now

  1. Realign your context (Clauses 4.1 and 4.2). Review climate change, supply chain constraints and the needs of interested parties, and record the outcome.
  2. Run a gap analysis. Compare your current system with the published 2026 editions and rate each gap so you can prioritise.
  3. Update documented information. Revise the manual, procedures, registers and records that the gaps affect.
  4. Train people. Brief top management on the new leadership and culture requirements, and train internal auditors on the changes.
  5. Audit your readiness. Hold an internal audit and management review against the new edition before you book the transition audit.
  6. Agree dates with your certification body. Plan the transition audit alongside a surveillance or recertification visit to reduce cost.

Frequently asked questions

Is my ISO 9001:2015 or ISO 14001:2015 certificate still valid?

Yes, during the transition period. Certificates to the 2015 editions stay valid until the transition deadline, but you must complete a transition audit to the 2026 edition before then.

Should I wait for ISO 45001:2027 before starting?

No. Start ISO 14001 and ISO 9001 now, and build your context, climate and change management work so it can be extended to ISO 45001 when the final text is published.

How long does a transition take?

For a well-maintained system, the gap analysis, document updates, training and internal audit usually fit into a few months. Larger or multi-site organisations should allow more time.

Does a consultant issue the certificate?

No. Certificates are issued only by accredited certification bodies. Himaya Prevention prepares your system and your team so the transition audit goes smoothly.
