Comparison of Standards
Changes and Updates in ISO 14001:2026 Compared to 2015
The revision of ISO 14001 clarifies existing requirements and sets new technical priorities. While the basic structure remains unchanged, ISO 14001:2026, published on April 15, 2026, clarifies key content and emphasizes topics such as climate change, biodiversity, life cycle assessment, and change management.
This raises the question for companies: What are the key differences between ISO 14001:2015 and ISO 14001:2026 – and what implications does this have for certified environmental management systems?
Our free white paper offers a structured comparison between existing and new standard requirements and clearly outlines the differences between the 2015 and 2026 versions.
Overview of the White Paper
- Detailed Comparison of Standards: A tabular comparison of key requirements from ISO 14001:2015 and ISO 14001:2026
- Key Changes: Newly added, clarified, and structurally revised requirements
- Support for Transition Planning: Guidance for internal assessment during the transition to the new standard
Background
Environmental management systems are subject to a continuous process of development. In the course of the revision of ISO 14001, aspects such as climate change, biodiversity, and the life cycle perspective were specifically addressed and more firmly anchored in the standard. At the same time, the fundamental structure of the standard remains intact, though individual requirements have been refined.
This free white paper is based on the standard version ISO 14001:2026-04, published on April 15, 2026, and offers a structured comparison with the “old” ISO 14001:2015.
