ISO 14001:2015 — Environmental Management

ISO 14001:2026 is the Fourth Edition (published April 2026). It cancels and replaces ISO 14001:2015 and its Amendment 1:2024. Main changes: (1) Full incorporation of the latest ISO Harmonized Structure (HLS) requirements applicable to all management system standards. (2) Climate change is now fully embedded in §4.1 and §4.2 (previously only in the 2024 Amendment). (3) Clarification of requirements on key topics including environmental aspects (§6.1.2), compliance obligations (§6.1.3), and operational planning (§8.1). (4) New terminology clarifications in Annex A.

No. ISO 14001:2015 certificates remain valid until they are transitioned, and at the latest until 30 April 2029, the end of the transition set by Global ACI-TECH-3-TR 2029-04-30 (M); after that date an ISO 14001:2015 certificate is no longer valid whatever expiry date it prints. After 31 October 2027, new and initial certifications are issued only to ISO 14001:2026. CAS will notify all certified clients of their transition schedule and will support them through the transition audit process.

Global ACI TECH-3-004 classifies organisations into High, Medium, Low, or Limited environmental complexity based on the nature and gravity of their environmental aspects. This directly affects audit time and cost. High complexity (e.g. mining, chemicals) requires more audit days than Limited complexity (e.g. offices, business services).

Yes. CAS conducts integrated audits per Global ACI TECH-3-008 (formerly IAF MD 11), under which the combined audit time can be reduced by up to 20%, according to how integrated your management system is and how far the audit team can audit the standards together; it can also increase where the integrated audit is more complex. This is an audit-time rule applied to every client, not a discount. ISO 14001:2026 uses the same ISO Harmonized Structure as ISO 9001:2015 and ISO 45001:2018, making integration straightforward.

No. The standard requires the organisation to set environmental objectives appropriate to its context, demonstrate continual improvement, and meet its compliance obligations — but it does not prescribe specific performance levels or numerical targets.

The audit checks that your environmental management system meets the requirements of ISO 14001:2015, clauses 4 to 10. In practice this covers how you identify environmental aspects and compliance obligations, set environmental objectives, control operations from a life cycle perspective, prepare for emergencies, evaluate compliance and performance, and act on nonconformities. Auditors look for evidence of implementation, not only documents.

Not by itself. ISO 14001 requires the organisation to determine its compliance obligations, evaluate whether they are being fulfilled and act on any gaps. The certification audit checks that these processes exist and work. The certificate confirms conformity with the standard; it is not a permit or a legal ruling from a regulator.

No. ISO 14001 is a standalone standard and can be certified on its own. Because it shares the ISO Harmonized Structure with ISO 9001:2015 and ISO 45001:2018, it can also be audited alongside them in an integrated audit; in that case you receive separate certificates for each standard.

A CAS ISO 14001 certificate is valid for 3 years. The initial certification is year 1 of the cycle; surveillance audits in years 2 and 3, the first no later than 12 months after the certification decision, verify that the environmental management system continues to meet the requirements of the standard, and a recertification audit before the certificate expires renews it for a new cycle.

CAS currently certifies to ISO 14001:2015. ISO 14001:2026, the fourth edition, has been published by ISO and cancels and replaces ISO 14001:2015 and its Amendment 1:2024. CAS continues to issue EGAC-accredited certificates against ISO 14001:2015 until EGAC records its transition decision on CAS and re-issues Schedule 012418B for the 2026 edition (decision due by 30 April 2027 under Global ACI-TECH-3-TR 2029-04-30 (M)). After 31 October 2027, new and initial certifications are issued only to ISO 14001:2026, and every certified client completes the transition, including issue of the ISO 14001:2026 certificate, before 30 April 2029. All existing certificates remain valid until they are transitioned, and at the latest until 30 April 2029.
