Module 5 of 5 · ISO 14001:2026 · Block 5

Evaluation, improvement, and transition from the 2015 certification

As with every ISO standard revision, a transition period is expected in which certified companies will need to update their system.

Content reviewed on

Transition period

ISO standards typically give a two- to three-year window from publication for certified organizations to migrate to the new edition.

Transition audit

The migration is usually verified at the next surveillance or recertification audit with the certification body, without needing a full initial audit.

Preparation plan

A gap analysis between the current system and the expected requirements, with an action plan to close them before the transition audit.

What an auditor usually asks for

  • Expected standard publication date tracked
  • Gap analysis against the 2015 edition carried out
  • Transition action plan with owners and deadlines
  • Transition audit coordinated with the certification body

How to cover this block in Kimobox

  1. 1Log the gap analysis as a version-controlled record linked to your current ISO 14001:2015 system.
  2. 2Document the transition action plan with owners and dates in Kimobox.
  3. 3Keep evidence of the transition audit as a controlled document.

The transition plan stays documented with its deadlines, ready to review at every surveillance audit.
