ISO Releases New Version of ISO 14001 for 2026

When the International Organization for Standardization (ISO) released its 2015 version of ISO 14001 for environmental management systems, sustainability was still struggling to find a seat at the corporate leadership table, many environmental regulations were still in the planning stage, and the world of data analysis had yet to be revolutionized by the application of artificial intelligence (AI).

ISO's new 14001:2026 standard aims to help companies improve environmental performance and ensure long-term resilience in a world in which sustainability is being buffeted by strong winds from economic fragility, the climate crisis, and geopolitical tension.

ISO 14001:2026 is designed to help organizations protect the environment from adverse impacts of their business operations, as well as to protect the business from the potential impacts of environmental degradation. It also helps organizations meet customer requirements for product and service design, supports regulatory compliance, and facilitates communication of the organization's environmental efforts to stakeholders.

“Environmental risks are increasingly interconnected,” said Susan Taylor Martin, chief executive at BSI, during a webinar led by BSI and ISO. “Climate impacts are accelerating, biodiversity loss is intensifying, stakeholder expectations are rising, and the demand for transparency has never been greater.” Taylor said that organizations are under increasing scrutiny from investors, regulators, customers, and communities that are demanding credible evidence of environmental action.

Research from the Standards Council of Canada (SCC) showed that adoption of ISO 14001 can have a significant economic impact at both the organizational and the national levels. According to the research, UPCON Corporation in Japan reduced its carbon dioxide (CO2) emissions by 90% by using ISO 14001, while a 1% increase in ISO certifications was found to contribute to a 0.14% reduction in greenhouse gas (GHG) emissions per unit of GDP.

“It's given us a robust framework that's allowed us to both measure and monitor the impact of our works,” said Julie Davidson, head of Business Assurance at Jointline. “It gives us a structured method for early identification of risk and to therefore reduce it and hopefully exceed the expectations that our clients have of us.”

Amarjit Kaur, director of SHEMSI Sdn Bhd, noted that ISO 14001 has become a critical component of customer and investor expectations.

“In terms of acquiring funding and investment, investors now look at organizations' sustainability performance,” said Kaur. “Even rating agencies are looking at environmental performance. In S&P Global's assessments, ISO 14001 is specifically mentioned, and other schemes like EcoVadis mention ISO 14001.”

Continuous Improvement of Organization

A management system is not a technology platform or digital solution. According to the ISO, it is a “set of interrelated or interacting elements of an organization to establish policies and objectives as well as processes to achieve those objectives.”

An environmental management system (EMS) manages environmental aspects to meet compliance obligations and address risks and opportunities. It can cover a single discipline or several disciplines and can include the entire organization, sections of the organization, or functions across a group of organizations.

An EMS can also be a component of an integrated management system (IMS) that contains other management systems, most frequently a quality management system (QMS) managed through ISO 9001:2015 and a health and safety management system managed through ISO 45001:2018. ISO's management system standards share a common harmonized structure designed to facilitate the integration of resources from other management systems into an IMS.

ISO's approach to management systems is built on the Plan-Do-Check-Act (PDCA) cycle, sometimes known as the Shewhart Cycle after physicist Walter Shewhart or the Deming Cycle after management expert W. Edwards Deming. PDCA provides a four-step iterative process to achieve continuous improvement in a management system:

• Plan: Establish objectives and processes necessary to deliver results in accordance with the policy.
• Do: Implement the processes.
• Check: Monitor and measure processes against the policy and report the results.
• Act: Take action to continuously improve.

The image below shows the relationship of the PDCA cycle to the harmonized structure of ISO's standards for management systems.

Making Systems Thinking a Priority

ISO 14001:2026 includes the following three significant updates:

Context: This update relates to environmental conditions, which are defined as the “state or characteristic of the environment as determined at a certain point in time.” While this requirement already existed in ISO 14001:2015, it now lists types of environmental conditions for consideration, including pollution levels, climate change, and biodiversity. It also requires that organizations understand how environmental conditions impact the organization and are impacted by it.

Alignment with Harmonized Structure: The harmonized structure has been refined to facilitate an IMS with other management system standards such as ISO 45001:2018 and ISO 9001:2015. There are terminology changes related to risks and opportunities, a new clause on change management, expanded requirements for “externally provided products, services, and processes” to replace the term “outsourced,” new documentation requirements for audits, and a finer distinction of the components of a management review.

Enhanced and Strengthened Annex A: Annex A, which provides guidance on requirements and how clauses are connected, now has a greater emphasis on understanding linkages across clauses, systems thinking across the entire standard, and explanations for requirements. Clauses are no longer considered in isolation but as part of the overall system. Organizations will now find it easier to design systems suited to their context while reducing unnecessary documentation and improving the performance of the management system overall.

For large organizations, this will support integration across environmental management, risk management, and sustainability reporting while reducing duplications and strengthening governance. For small- and medium-sized enterprises (SMEs), it means a structured-yet-flexible framework, scalable implementation, reduced documentation burdens, and more support for customer requirements and supply chain expectations.

Next Steps to Certification

While the details of the transition from ISO 14001:2015 to ISO 14001:2026 are still to come, experts in the webinar by BSI and ISO noted that the transition period will likely be up to three years, depending on when the organization was certified under ISO 14001:2015, during which time the earlier certification will remain valid.

Howard Dawes, global training technical lead for Sustainability and Safety, Health and Wellbeing at BSI, noted that for most organizations, the transition process should include an understanding of the changes, conducting a gap assessment of the EMS to prioritize high-impact areas, updating the EMS, and then engaging the certification body.

“Focus on integration, not just compliance or conformance,” said Dawes. “The most successful transitions or adoptions are those that embed the changes into how the organization actually operates.”

Dawes also addressed whether organizations should prepare for significant changes to their EMS because of the move to the new standard.

“Many organizations will need to take into account their own individual circumstances,” said Dawes. “For many, I think they will make a smooth and quick transition between the 2015 and the 2026 edition. But for others, I think to give them confidence about the smooth transition, it would be prudent to carry out a gap analysis between requirements of 2026 and their current environmental management system.”
