Transitioning to ISO 14001:2026

• Written by: Deb Piatt, Sr. QMS, EMS and EEI Manager

The release of ISO 14001:2026 marks the latest revision to the environmental management system standard.

While the core framework of ISO 14001 remains, the 2026 revision introduces focused changes to requirements, terminology, and structure.

This article reviews the key updates in ISO 14001:2026, including changes related to organizational context, leadership, risks and opportunities, life-cycle perspective, change management, externally provided processes, performance evaluation, and continual improvement.

ISO 14001:2026 was published on April 15, 2026, replacing ISO 14001:2015.

Organizations currently certified to ISO 14001:2015 should use the transition period to evaluate their existing Environmental Management Systems (EMS), conduct gap assessments, provide staff and auditor training, and update the EMS where necessary to meet the ISO 14001:2026 requirements.

Clause 4 – Context of the Organization

• Organizations are required to consider relevant environmental conditions such as climate change, pollution, availability of natural resources, biodiversity, and ecosystem health when determining the context in which they operate.
• Consider how environmental conditions can affect the organization and how the organization can affect those environmental conditions.
• The requirements related to interested parties remain, including determining which relevant needs and expectations become compliance obligations.
• The EMS scope is to be defined by considering the organization’s activities, products, and services and where the organization has the authority or ability to exercise control or influence.

Clause 5 – Leadership and Commitment

• The words “meet compliance obligations” replace “fulfil compliance obligations.”
• Top Management remains responsible for demonstrating leadership and commitment to the EMS and supporting relevant roles that contribute to the EMS effectiveness.
• Top Management is to ensure environmental considerations into the organization’s business processes, where applicable.
• The environmental policy is to include the organization’s commitments related to protection of the environment and prevention of pollution.

Clause 6 – Planning

The structure of Clause 6 has been revised.

• Requirements for identifying and addressing risks and opportunities have been reorganized.
  • Clause 6.1.4 addresses the determination of risks and opportunities.
  • Clause 6.1.5 addresses planning actions to address identified risks and opportunities.
• Environmental aspects, compliance obligations, environmental conditions, risks, and opportunities continue to be considered as part of EMS planning.
• Potential environmental emergency situations are addressed separately from normal and abnormal operating conditions when evaluating environmental aspects.

Clause 6.3 – Planning of Changes

A new Clause 6.3, Planning of Changes, has been added.

The organization must plan changes that can affect the Environmental Management System.

Changes may include:

• New or modified processes
• New equipment or technology
• Changes in products or services
• Facility changes
• Organizational changes
• Changes in compliance obligations
• Changes involving suppliers or externally provided processes
• Other changes that can affect environmental performance or the EMS

Organizations that already use management-of-change, engineering-change, or project-management processes should determine whether environmental impacts and EMS requirements are included in those processes.

Life-Cycle Perspective

Consider environmental aspects associated with stages of the life cycle that the organization can control or influence.

Life-cycle stages includes:

• Raw material acquisition
• Design and development
• Operations
• Transportation and delivery
• Use
• End-of-life treatment
• Final disposal

Note: ISO 14001 does not require organizations to conduct a formal life-cycle assessment.

Organizations are required to consider the life-cycle perspective when determining environmental aspects and establishing operational controls.

Clause 7 – Support

The overall structure of Clause 7 remains basically unchanged.

Continue to address needs for EMS:

• Resources
• Competencies
• Awareness
• Communication
• Documented information

Documented information must be available where required by the standard and where determined necessary by the organization for the effectiveness of the EMS. Terminology for documented information has been revised.

• “Maintain documented information” is replaced by “shall be available as documented information”
• “Retain documented information” is replaced by “documented information shall be available as evidence of”

Clause 8 – Operation

• The words “outsourced processes” have been replaced with “externally provided processes, products and services.”
• Organizations are to determine the type and extent of control or influence to apply to externally provided processes, products, and services.
• Environmental requirements need to be communicated to external providers.
• Life-cycle considerations apply to operational planning and control.
• Emergency preparedness and response should address all potential environmental emergency situations associated with the organization’s activities, products, services, and environmental aspects.

Externally provided processes, products, and services may include:

• Suppliers
• Contractors
• Service providers
• Transportation providers
• Waste management providers
• Other external organizations that can affect environmental performance or compliance obligations

Clause 9 – Performance Evaluation

• Monitor, measure, analyze, and evaluate environmental performance and the effectiveness of the EMS.
• Internal audit programs need to include defined audit objectives.
• Retain documented information as evidence of implementation of the audit program and audit results.
• Management review is reorganized with distinct sub-clauses for inputs and outputs.
• Evaluate the suitability, adequacy, and effectiveness of the EMS during Management Review.

Clause 10 – Improvement

The structure of Clause 10 has been revised.

• Continual improvement remains a requirement of ISO 14001:2026.
• Identify opportunities for improvement and implement actions necessary to achieve the intended outcomes of the EMS.
• Address and correct nonconformities.
• Corrective actions need to address the causes of nonconformities and prevent recurrence.
• Retain documented information related to nonconformities, actions taken, and corrective-action results.

Information from monitoring and measurement, compliance evaluations, internal audits, management review, nonconformities, corrective actions, and environmental objectives are to be used as inputs for improvement activities and management review.

Summary of Key Changes

• Within the context of the organization, environmental conditions such as climate change, pollution, biodiversity, natural resources, and ecosystem health need to be identified.
• The words “meet compliance obligations” replace “fulfil compliance obligations.”
• Requirements for identifying risks and opportunities and planning actions have been reorganized.
• New Clause 6.3 addresses planning of changes.
• Potential environmental emergency situations are distinguished from normal and abnormal operating conditions when evaluating environmental aspects.
• Life-cycle perspective continues to apply to activities, products, and services that the organization can control or influence with emphasis on the Life-cycle stages.
• The terminology “externally provided processes, products and services” replaces references to outsourced processes.
• Internal audit programs must include defined audit objectives.
• Management review is reorganized into distinct sub-clauses for inputs and outputs.
• Clause 10 has been reorganized while retaining requirements for nonconformity, corrective action, and continual improvement.
• Terminology, notes, and Annex A guidance have been revised in several areas.

Transition Timeline

Organizations currently certified to ISO 14001:2015 have until April 30, 2029 to complete the transition to ISO 14001:2026.

Note: Per Global ACI Transition Requirement, beginning October 31, 2027, new and initial accredited certifications are to be issued to ISO 14001:2026 rather than ISO 14001:2015. (reference: Global ACI-TECH-3-TR 2029-04-30 (M)).

Organizations are advised to work directly with their certification body to determine when their transition audit will occur and whether the transition will be completed during a surveillance audit, recertification audit, or separate transition audit.

Recommendation: Organizations should update their EMS where required by the revised standard rather than rewriting existing processes and documentation that continue to meet the requirements.
