Environmental Management Systems ISO 14001: 2026 is coming

26^th February 2026

ISO 14001:2015 the environmental management standard is undergoing revision in early 2026.

International Organization for Standardization (ISO) released the Final Draft International Standard (FDIS) at the end of January 2026 and ISO are now expected to release the new version of ISO 14001 around mid-April 2026. It has been 10 years since the standard was last updated and is an expected iteration and update, building in additional enhancements and clarifications. It remains under the harmonised “Annex SL” structure which has been so successful aiding with QHSE systems integration.

Why the change? ISO Standards are revised and updated periodically; focusing the purpose of the standards in a relevant, modern context. The update will officially include the text of The climate change amendment introduced in 2024 (ref). The update will officially include:

The text of the climate change-related amendment (ref. ISO 14001:2015/Amd1:2024) introduced in 2024;

Additional clarifications with an expanded Annex A (helpful explanatory text at the back of the standard), and

Further alignment with the Annex SL (ISO’s harmonised structure) for management system standards.

Are the changes significant?

Whilst there are some new clauses and improved layout of clauses, mainly the changes are around clarifying and enhancing the standard. Many well implemented ISO 14001:2015 systems will already cover many of these enhanced elements; to gauge your own organisation’s readiness for the ISO 14001:2026, building understanding first of the new requirements and then undertaking a Gap Analysis process will help identify areas for improvement.

A flavour of the FDIS ISO 14001:2026 proposed changes:

Understanding the organisation and its context/ Understanding the needs and expectations of interested parties (Clause 4.1.and 4.2): The climate change amendment (https://www.iso.org/standard/88209.html) which was introduced in 2024 is formalised into the body text, including specific note of issues to consider such as pollution levels, availability of natural resources, climate change, biodiversity and ecosystem health. As organisations rely on many ecological and environmental spaces in which they or their supply chain and customers operate, building in these considerations into EMS decision making is a move to bring external environment considerations into the boardroom. As an example, consider crop failure as a result of biodiversity loss or climate change and its subsequent operational impacts for a food manufacturer whom is reliant on this crop.

Environmental Management System (Clause 4.4) The EMS itself is clarified, for example, that organisations may have combined processes which meet several requirements, and/or integration with other business processes. This provides flexibility on how EMS processes are designed, and focuses on what’s important – i.e. environmental performance outcomes rand integration with how the organisation runs, rather than emphasising separate processes or procedures.

Leadership and commitment (Clause 5.1) – enhancing the expectation on leadership to promote a culture that engages persons working on behalf of the organisation in activities that contribute to the EMS outputs. A link to leadership engagement combining with enhancing trust with their organisations interested parties is an interesting emphasis. So many organisations have complex supply chains, and working together, for example on net zero goals or sustainable sourcing can have a positive multiplier effect for both delivery and pace of delivery on environmental performance.

Environmental aspects and impacts (Clause 6.1.2) – enhanced focus on considering life cycle for aspects and control/influence over these impacts, with additional explanatory text in Annex A relating to methods (e.g. grouping) of identifying environmental aspects and impacts. There is reassurance that formal life cycle assessment is not required to meet the standard. Annex A also specifically provides additional guidance on the inclusion of potential emergency situations which may give rise to new environmental aspects. The linkage of environmental aspects and impacts to risks and opportunities is further enhanced.

Risks and Opportunities (Clause 6.1.4) *New Section* – Now requires a documented process. In alignment with other ISO standards, environmental management risks and opportunities and their interaction with environmental aspects are enhanced – opportunities such as circular economy, improvements in land management for biodiversity impact. Risk based considerations are explained more fully in terms of climate impacts, geographic areas, biodiversity reduction impacting on an organisation – directly or through value chain. As usual within an ISO 14001 EMS, it’s all about identifying and mitigating risks and enhancement of opportunities.

Planning of Changes (Clause 6.3) *New Section* Change management for the EMS has a new specific planning clause – for organisational changes which are relevant to the environmental management system, a structured approach is to be taken to change management. This means having a plan for temporary or permanent changes which can impact on environmental performance – these can be far-reaching and a change trigger may come from external factors like natural disasters or political/ regime change. Changes can impact on resources, knowledge, training, equipment, supply chain matters etc, so planning is essential, including revision cascade into environmental aspects, impacts, risks and opportunities to align with EMS objectives/outputs.

Internal Audit (Clause 9.2) this clause includes a clarification for the documented information required to be available. This is highlighted in sub-clause 9.2.2 Internal Audit Programme, forming a mini-checklist. The wording is re-organised for clarity, but the intent is the same as the previous standard.

Management Review (Clauses 9.3.1, 9.3.2 and 9.3.3) *Reorganised Section* The Management Review section has been re-organised and better structured into three sub-clauses. After the General sub-clause, the section is divided into clear management review inputs (clause 9.3.2) and management review results (clause 9.3.3). These form into a structured check for agendas, inputs and outputs for organisations to use for the management review process.

Takeaways

Whilst there are a handful of new clauses (the concepts are not new, but they are more prescriptive than the previous standard), and obvious work to be done in aligning with the intent and requirements for current EMSs aligned to ISO 14001:2015, the larger scale updates are actually contained in the Guidance, Annex A.

The guidance in Annex A of the document has been updated and clarified, to support the intent of the ISO 14001 clauses (including clause changes) to help with consistent understanding and interpretation of the requirements. This is helpful for viewing your organisations’ performance management through an environmental lens, covering internal and external issues. ISO 14001 remains a powerful tool if deployed with commitment and due consideration, and with the growing emphasis on supply chains and engagement the revision is hitting the right notes for collaboration and improvement.

When will the new ISO 14001:2016 standard be published?

The ISO 14001:2026 standard update date based on current indications are that this is expected in mid-April 2026. There will be a mandatory transition timetable announced by the International Accreditation Forum (IAF) and your external certification audit body will also provide information.

Transition timelines

The transition period for registered sites (those with a current ISO 14001:2015 Certificate) is likely to be up to 3 years, so it’s worth starting now to adapt and improve your systems to align with the new standard. As usual, during this timeline your ISO 14001:2015 Certificate will remain valid so long as your systems and performance are in conformance.

Noting it will take the Certification Bodies some 0-6 months to themselves be accredited to deliver external audits for the new standards, there is an opportune time now to plan your transition in a controlled way – maybe an opportunity to fire up your new Clause 6.3!

What do I have to do next?

Follow your Certification Body’s website and updates; the Arthian website www.arthian.com, Arthian LinkedIn pages and industry body updates.

It is recommended to diarise the change, note in your management systems and Management Review meetings that the change is coming and purchase a copy of the new standard when published.
