When was ISO 14001:2026 published?

The fourth edition, ISO 14001:2026, was published in April 2026. It cancels and replaces the 2015 edition and incorporates the 2024 amendment on climate change (source: ISO 14001:2026).

How long is the transition period?

After publication, certified organizations usually have a three-year transition period set by the IAF resolution. ISO 14001:2015 certificates remain valid during this window, while certification bodies are accredited to the new version and carry out transition audits.

Is climate change a new requirement?

The 2026 edition incorporates amendment ISO 14001:2015/Amd 1:2024. The organization must determine whether climate change is a relevant issue when analysing its context (clauses 4.1 and 4.2) and consider interested parties' expectations on the subject.

Do we have to redo everything to migrate to ISO 14001:2026?

No. The fundamentals remain stable: the PDCA cycle, life cycle perspective, environmental aspects and impacts, compliance obligations and continual improvement. The transition mainly means updating the context analysis (including climate), aligning the system with the updated harmonized structure, and reviewing operational control in light of the clarifications.
