ISO/FDIS 14001:2026 Environmental management systems - Requirements with guidance for use

- A strengthened focus on a broader range of environmental conditions in addition to climate change for the analysis of the organisational context, such as pollution levels, biodiversity and availability of natural resources
- Restructured and clarified requirements related to risk and opportunity processes
- New clause and requirements for the planning of changes
- Strengthened emphasis on life cycle perspective in the environmental aspect process
- For operational controls, the focus is extended from “outsourced processes” to “externally provided processes, products and services”

In addition, the guidance section has been substantially extended and improved for various clauses to support interpretation of the various requirements.

Transition period expected to be three years

ISO is planning to publish the revised standard in April 2026, replacing ISO 14001:2015. The FDIS was released on 5 January 2026 for an eight-week ballot and comment period.

Based on a draft mandatory document from the International Accreditation Forum (IAF), the transition period for ISO 14001:2026 is expected to be three years. If confirmed, this means that all certificates issued to ISO 14001:2015 will need to be transitioned to the new edition before May 2029 to remain valid.
