ISO 14001:2015 vs. ISO/FDIS 14001:2026
Comparison of standard requirements
ISO 14001:2015 vs. ISO/FDIS 14001:2026-01
The revision of ISO 14001 specifies existing requirements and sets new technical priorities. While the basic structure remains the same, the final draft ISO/FDIS 14001:2026-01 specifies central content and strengthens topics such as climate change, biodiversity, life cycle perspective and change management.
This raises the question for companies: What are the main differences between ISO 14001:2015 and ISO 14001:2026 - and what are the implications for existing environmental management systems?
Our free white paper offers a structured comparison between existing and new standard requirements and presents the differences between 2015 and 2026 in a comprehensible way.

Background
Environmental management systems are subject to a continuous development process. In the course of the revision of ISO 14001, aspects such as climate change, biodiversity and the life cycle perspective in particular will be specified and anchored more firmly in the standard. At the same time, the basic structure of the standard is being retained, but individual requirements are being made more specific and thematically sharpened.
The free white paper is based on the final draft ISO/FDIS 14001:2026-01 and offers a structured ISO 14001 FDIS comparison between ISO 14001:2015 and the planned revision. The contents are clearly structured and enable a comprehensible classification of relevant changes.
