What is ISO 14001? Requirements, Benefits & Certification

ISO 14001 is an international standard for Environmental Management Systems (EMS) which helps organisations understand their impact on the environment and manage this impact, to continue to improve.

Organisations today are looking to be more sustainable and use resources efficiently, whilst following environmental legislation.

Using ISO 14001 will help organisations achieve these goals by using an Environmental Management Plan.

The latest version of ISO 14001 (ISO 14001: 2026) was released in April 2026.

1. What Is ISO 14001?

ISO 14001 is a standard created by the International Organization for Standardization (ISO).

It provides the requirements for an Environmental Management System.

It helps organisations understand their environmental aspects.

It covers;

• Environmental protection
• Pollution prevention
• Waste management
• Saving energy and water
• Compliance
• Continuous improvement

The standard can be used by both large and small businesses across any sector.

Further information can be found on the ISO 14001:2026 page.

2. Environmental Management System (EMS)

Organisations use the Environmental management system to get involved with environmental activities.

They will have a clear policy, roles, processes and objectives to manage their environmental impact.

For example,

If a manufacturing business creates wastewater, uses electricity and produces waste, they can, using ISO 14001, understand their environmental impacts, create controls and track improvements. The EMS uses the PDCA method.

This creates a continuous improvement cycle for the environment.

3. Key Requirements Of ISO 14001

There are many management requirements within ISO 14001.

Clause 4 – Understanding the context of the organisation

This requires understanding how the organisation will operate and identifying interested parties. This determines the EMS scope.

Clause 5 – Leadership

Leaders need to demonstrate commitment to managing the environment. They should be involved with creating the environmental policy, having clear roles and providing enough resources.

Clause 6 – Planning

Actively involved organisations will identify (environmental) aspects, legal compliance obligations and (risk and) opportunities. They will also set and monitor environmental objectives and targets.

Clause 7 – Support

The resources section includes: documentation, appropriate knowledge base, competence, awareness, communication and documented information.

Clause 8 – Operation

Controls will be created to manage significant environmental aspects. This could include managing waste, pollution prevention and emergency preparedness.

Clause 9 – Performance Evaluation

Performance is monitored and evaluated. This includes carrying out internal audits, legal compliance and management reviews.

Clause 10 – Improvement

Businesses will address non-conformities, corrective actions and continual improvements to environmental management.

4. Benefits Of Being ISO 14001 Certified

Implementing ISO 14001 can offer many benefits.

A. Improved Environmental Performance

Companies can understand their impact on the environment and take steps to reduce pollution and waste.

B. Better Legal Compliance

Using an EMS will help organisations identify and manage environmental compliance obligations.

C. Reduce Costs

Reduction in electricity, water and raw material costs.

D. Improve Business Image

This shows the business has had an independent verification of its environmental management.

E. Better Risk Management

Organisations can understand the risk and put controls in place.

F. New Business Opportunities

ISO 14001 could be used to help qualify suppliers and tender where an environmental management certificate is required.

5. How To Become ISO 14001 Certified – Guide

Organisations can follow the steps below.

Step 1 – Gap Analysis

Understand current environmental practices and ISO 14001 requirements. Identify any missing processes, controls and documentation.

Step 2 – Environmental Policy

Create a policy showing how the company contributes to the environment.

Step 3 – Identify Environmental Aspects

Look at what activities may have an impact.

This could include;

• Use of electricity
• Use of water
• Creation of waste
• Emissions into air
• Handling chemicals.

Step 4 – Implement EMS

Create processes, roles, objectives and monitoring. Train staff on the relevant practices.

Step 5 – Internal Audit

Ensure the management system meets requirements and is implemented.

Step 6 – Management Review

Results from environmental performance and audit are presented to senior management. Objectives and opportunities for improvement are also provided.

Step 7 – Certification Audit

The Environmental Management System is externally certified.

This normally includes Stage 1 and Stage 2 audits.

Because DNV has a long tradition in ISO 14001 certification, the organization has adopted a web-based system with a timeline projection concerning companies' certification renewal.

6. ISO 14001:2026 - Current version

Publication date: 15 April 2026.

A: It supersedes the former version (ISO 14001:2015) and features new and improved information about environmental management.

The revised edition provides:

• A clearer management system structure.
• Improved guidance on environmental priorities.
• Greater clarity regarding risks and opportunities.
• Stronger consideration of environmental conditions.
• Better integration with other ISO management systems.

Previous edition certified organizations should contact their certification bodies for transition options available.

7. Difference Between ISO 14001 and ISO 9001

While both standards are management system standards, the main difference is their purpose.

An organization can have both standards implemented in a single integrated management system.

8. ISO 14001 – Healthcare and Medical Laboratory Use

ESG is also relevant for hospitals, diagnostic centres and medical laboratories.

Healthcare facilities produce biomedical waste and utilise electricity, water and other resources.

An EMS may be able to assist these organisations with:

• Waste segregation and disposal.
• Chemical waste handling.
• Energy consumption.
• Water conservation.
• Environmental emergency preparedness.
• Compliance with applicable environmental regulations.

For a medical laboratory, it is ISO 14001 environmental management and ISO 15189:2022 laboratory quality and competence.

Note: ISO 14001 cannot be a substitute for accreditation of the medical laboratories, and there is no legal requirement for biomedical waste.

9. ISO 14001 Checklist

Other documented information required by the organization may include:

• Environmental policy.
• EMS scope.
• Environmental aspects and impacts register.
• Compliance obligations.
• Environmental objectives.
• Operational control procedures.
• Training and competency records.
• Environmental monitoring records.
• Internal audit reports.
• Management review records.
• Corrective action records.

The type of documentation also needed may vary depending on the nature of the organisation's activities, environmental risks, and which requirements of ISO 14001 are met.
