The updated environmental management system standard, ISO 14001:2026, has now been officially released. This new version replaces ISO 14001:2015 and incorporates the climate change amendment that was issued in 2024.
ISO 14001 is among the most widely adopted environmental management system standards worldwide. It supports hundreds of thousands of organizations in managing their environmental responsibilities and driving continual improvement in environmental performance.
Ongoing reviews are critical to ensure that international standards remain relevant and effective over time.
ISO 14001 has proven its value in supporting systematic environmental management and improved environmental performance. We therefore welcome the publication of the new edition.

“It is key that standards such as ISO 14001 are reviewed and revised regularly with the involvement of subject matter experts. This ensures that the standard evolves based on user experience and remains fit for purpose in addressing emerging environmental challenges and sustainability trends,” Tollefsen adds.
Moderate updates in the revised standard
A central objective of the revision was to clarify existing requirements while keeping the introduction of new requirements to a minimum. In parallel, the standard has been aligned with the most recent version of ISO’s Harmonized Structure for management system standards.
Overall, the scope of the changes is considered moderate and is not expected to demand significant implementation efforts from organizations that are already certified to ISO 14001:2015.
Key changes in ISO 14001:2026
Among the main changes in ISO 14001:2026 are:
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
Strengthened emphasis on life cycle perspective in the environmental aspect process
New requirements for planning and managing changes
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 across several clauses to support interpretation of the requirements.
Three‑year transition period
The transition period for ISO 14001:2026 is expected to be three years. Certificates issued to ISO 14001:2015 must transition to the new edition before May 2029 to remain valid.
DNV supports organisations throughout the transition to ISO 14001:2026 through webinars, training and transition audits, helping them align their existing certification with the revised standard.
