The revised environmental management system standard, ISO 14001:2026, has now been officially released. This edition replaces ISO 14001:2015 and incorporates the climate change amendment issued in 2024.
ISO 14001 is one of the most widely used environmental management system standards globally. It supports hundreds of thousands of organisations in managing their environmental responsibilities and continually improving environmental performance.
Regular reviews play an important role in ensuring that international standards remain relevant, effective, and aligned with evolving expectations.
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
One of the main objectives of the revision was to provide greater clarity around existing requirements while limiting the introduction of new ones. At the same time, the standard has been aligned with the latest version of ISO’s Harmonized Structure for management system standards.
Overall, the changes are considered moderate and are not expected to require significant implementation effort for organisations already certified to ISO 14001:2015.
Key updates 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 by May 2029 in order to remain valid.
DNV supports organisations throughout the transition to ISO 14001:2026 through webinars, training programmes, and transition audits, helping them align existing certifications with the revised standard.
