What Is Documented Information in ISO 14001:2026?

What Is Documented Information in ISO 14001:2026?

Documented information is information that an organization needs to control and maintain as part of its Environmental Management System.

It can include documents that describe how a process should be performed and records that provide evidence that a process has taken place.

The organization determines what documented information is necessary to support its EMS and demonstrate conformity with ISO 14001:2026.

Why Is Documented Information Important in ISO 14001:2026?

Documented information helps an organization maintain consistency and demonstrate that its EMS processes are working as intended.

For example, documented information can help employees understand operational requirements, while records can provide evidence of monitoring, audits, training, corrective actions and management reviews.

What Types of Documented Information Are Used in ISO 14001:2026?

ISO 14001:2026 can involve different types of documented information depending on the organization's EMS.

Examples may include the environmental policy, environmental objectives, information about environmental aspects and impacts, compliance-related information, operational control information, monitoring results, internal audit results and management review results.

The organization does not need to create documents simply because another organization uses them. Documented information should be relevant to the organization's own EMS.

What Is the Difference Between Maintaining and Retaining Documented Information?

In an EMS, maintaining documented information generally refers to keeping information current and available when it is needed.

For example, an organization may maintain an environmental procedure or operational control document.

Retaining documented information generally refers to keeping records as evidence that something has occurred or that a requirement has been fulfilled.

For example, an internal audit report can be retained as evidence that an internal audit was completed.

What Documented Information Is Required for an ISO 14001:2026 Audit?

The required documented information depends on the applicable ISO 14001:2026 requirements and the organization's EMS.

Auditors may review the environmental policy, objectives, information related to environmental aspects, compliance obligations, monitoring and measurement results, internal audit evidence, management review results and corrective-action records where applicable.

The auditor uses this information together with interviews and observations to evaluate whether the EMS has been effectively implemented.

How Does Documented Information Support Environmental Policy?

The environmental policy is maintained as documented information and provides the overall direction for the organization's EMS.

It can be supported by other documented information that shows how the organization's environmental commitments are implemented through objectives, processes and controls.

Read What Is the Environmental Policy in ISO 14001:2026? for a detailed explanation.

How Does Documented Information Support Environmental Objectives?

Environmental objectives need to be supported by appropriate planning and evidence.

An organization may maintain information about its objectives, targets, responsibilities, resources, timelines and methods for evaluating progress.

Monitoring and measurement records can then provide evidence of progress toward those objectives.

How Is Documented Information Controlled?

Documented information needs to be controlled so that it is available where and when it is needed and is adequately protected.

Organizations should consider issues such as access, distribution, storage, preservation, changes and retention.

Controls help prevent employees from accidentally using outdated information or losing important EMS records.

How Do Auditors Evaluate Documented Information in ISO 14001:2026?

Auditors may review documented information to determine whether the organization's EMS meets applicable requirements.

However, an audit is not limited to checking documents. Auditors can compare documented information with interviews, observations and actual workplace activities.

For example, if an organization has documented operational controls for waste management, the auditor may check whether employees understand those controls and whether they are actually being followed.

Does Every Organization Need the Same ISO 14001:2026 Documents?

No. ISO 14001:2026 allows organizations to determine the documented information necessary for their own EMS.

A large manufacturing organization may need more detailed documented information than a small office because its activities, environmental aspects and operational controls may be different.

The focus should be on having enough documented information to support an effective EMS and demonstrate conformity.

How Does Documented Information Support Continual Improvement?

Documented information provides evidence that an organization is monitoring its EMS and taking action when improvements are needed.

Audit findings, corrective actions, environmental performance results and management review outputs can help identify opportunities for improvement.
