ISO 14001:2026 — what changes compared to the 2015 edition

On 18 May 2026, BS EN ISO 14001:2026 entered into force — the fourth edition of the international standard for environmental management systems (EMS). It replaces the current BS EN ISO 14001:2015 (and amendment /A1:2024).

Good news for already certified organisations: unlike the 2004 → 2015 transition, which fundamentally changed the structure of the standard, the 2015 → 2026 transition is evolutionary. Both editions share the same harmonised structure (clauses 1–10), the same term groups and the same Annex A. The changes are targeted and concentrated in a few specific areas.

The essence of the change — in three directions

The analysis identified three main areas where the changes are concentrated:

• Climate change (clause 4) — explicitly introduced in 4.1 and 4.2. Organisations must determine whether climate change is a relevant factor for their environmental management system.
• More visible risk-based approach and planning of changes (clause 6) — two new subdivisions that increase the visibility of risk management.
• Clearer text — updated and aligned with the latest ISO harmonised structure (2022 version) and with the sustainable development goals.

What this means for the 2015 → 2026 transition

For an organisation already certified to ISO 14001:2015, the transition is moderate. It is enough to address the specific additions:

• account for climate change as a factor in the analysis of context (4.1) and of interested parties (4.2);
• identify and document the management of risks and opportunities (new 6.1.4);
• introduce a process for planning changes to the EMS (new 6.3);
• review procedures against the clarifications in clauses 7–9 and the updated Annex A.

The core framework — policy, aspects, compliance obligations, objectives, operational control, audit, management review and continual improvement — remains unchanged.
