ISO 14001:2026 – What Has Changed

ISO 14001:2026 has replaced ISO 14001:2015, and certified organisations have until 30 April 2029 to move across. The changes are moderate, but they touch the parts of an environmental management system that auditors look at most closely. Salvus can help you find the gaps and close them well before your transition audit.

What is ISO 14001:2026?

The revised environmental management system standard was published on 15 April 2026. It replaces ISO 14001:2015 and absorbs the climate change amendment issued in 2024. The aim of the revision was to clarify existing requirements rather than add a long list of new ones, so a well-run system will not need rebuilding. It will need a careful review.

The main changes

• Context of the organisation. You are now expected to consider a wider range of environmental conditions, not only climate change. Pollution levels, biodiversity and the availability of natural resources are all named.
• Risks and opportunities. The requirements have been restructured and clarified.
• Life cycle perspective. There is a stronger emphasis on life cycle thinking when you identify your environmental aspects.
• Managing change. There are new requirements for planning and managing changes to the system.
• Suppliers and contractors. Operational control now reaches beyond "outsourced processes" to all externally provided processes, products and services.
• Guidance. The guidance annex has been extended to help with interpretation.

Key dates for UK certified organisations

• 15 April 2026: ISO 14001:2026 published.
• 31 October 2027: UKAS-accredited certification bodies stop issuing new certificates to ISO 14001:2015.
• 30 April 2029: all certified organisations must have transitioned. ISO 14001:2015 certificates are no longer valid after this date.

Your certification body will confirm when your own transition audit will take place. Most organisations will transition at a planned surveillance or recertification visit, so the practical deadline is often much sooner than 2029.

How Salvus can help

• Gap analysis. A clause-by-clause review of your current system against ISO 14001:2026, with a clear, prioritised action plan.
• System updates. Practical help to revise your context review, aspects register, risks and opportunities, change management and supplier controls.
• Compliance obligations. A review of your legal register so that it supports the revised standard.
• Internal audit. An independent internal audit against ISO 14001:2026 before your certification body arrives.
• Briefings. Short, plain-English sessions for directors, managers and internal auditors on what has changed.

Our support is led by a qualified ISO 14001 lead auditor, so you get advice based on how the standard is audited in practice. If you also hold ISO 9001, we can review both standards in one exercise.
