ISO 50001 Certification: Energy Management System
ISO 50001 is an international standard for energy management systems that sets out clear requirements to help organisations take a structured approach to achieving systematic and measurable improvements in energy performance. By gaining a clear understanding of energy use, organisations can identify opportunities for efficiency, reduce consumption, lower costs, and make more effective use of equipment and processes.
Certification of your energy management system demonstrates compliance with ISO 50001 requirements. It also shows your commitment to improving energy performance and provides a credible basis for transparent and trusted communication of your organisation's energy performance.
What is the ISO 50001 standard?
ISO 50001 is applicable to organisations of any size, sector or location. It provides a structured framework for establishing an energy management system that enables more efficient and effective use of energy across operations and throughout the supply chain.
By meeting the requirements of the standard, organisations can systematically understand and reduce energy consumption, improve operational performance, and minimise environmental impact.
ISO 50001 helps you:
- Establish a systematic approach to managing energy performance across your operations
- Conduct an energy review to identify significant energy uses and prioritise improvement opportunities
- Set objectives and action plans that drive continual improvement in energy performance
- Implement consistent processes for monitoring, measuring and analysing energy use
- Improve energy performance, including energy efficiency, energy use and energy consumption
- Ensure effective monitoring, measurement, documentation and reporting of energy consumption
- Support emission reduction initiatives and reduce adverse impact from energy use Promote energy‑efficient practices internally and across the value chain
The standard is built on ISO's Harmonized Structure (HS), a set of aligned clauses that make it easy to be integrated with other management system standards such as ISO 14001 for environment and ISO 9001 for quality.
Value of ISO 50001 certification
Certification to ISO 50001 by an independent third party, such as DNV, demonstrates your organisation's commitment to improving energy performance and reducing environmental impact. It provides internal assurance that energy use is being managed in a structured and systematic way, while also signalling this commitment to customers, regulators and other stakeholders.
As a result, you get:
- Credible and transparent communication about your energy performance efforts
- Competitive advantages where energy‑efficient partners are prioritised
- Greater understanding and awareness around energy management among managers and staff
- Clear demonstration of your commitment to contribute to mitigate climate change

How to get certified to ISO 50001
To achieve certification, your organisation must first establish and implement an effective energy management system that meets the requirements of ISO 50001. DNV is an accredited independent third-party certification body and can support you throughout the entire process: from ISO 50001 training and self-assessments to gap analysis and certification services.
As a DNV customer, you also gain access to digital tools designed to help you maintain compliance, drive continual improvement, and manage every stage of your ISO 50001 certification journey with us.
Learn how to get started and be certified
-
-
Obtain the standard:
Get a licensed copy of the relevant standard and familiarise yourself with the requirements to decide whether certification or registration to this standard is appropriate for your organisation.
-
Review available literature and apply digital tools
Explore available literature, guidance from the standard owners (e.g. ISO/TS 9002 for ISO 9001, ISO 14004 for ISO 14001) and digital sources and tools that can support implementation. As a DNV customer, you also get access to tailored tools that can help you.

Assemble a team and define strategy:
Implementing a management system should be a strategic decision for the entire organisation. Senior management must be engaged in the decision, committed to it, and involved in shaping the system. They decide the business strategy the management system should support. In addition, you need a dedicated team to develop and implement your management system.
-
Determine competence needs:
First, your team responsible for implementing and maintaining the management system needs a thorough understanding of the chosen standards. Later, the wider organisation needs awareness training. DNV offers a variety of public and in-house courses worldwide that meet competence development needs at all levels of your organisation.
-
-
-
Review consultant options:
Independent consultants can advise on a workable, realistic and cost-effective implementation strategy if you do not already have this competence or capacity in-house.
-
Develop management system documentation:
Decide on an appropriate platform for your documented information (e.g. software, process map- or SharePoint-based). The right platform is important to ensure effective management, communication and implementation.
-
-
-
Determine, manage and document processes:
First, identify key processes – what they are, how they work and how they interact. Each process should have a clear purpose, defined responsibilities and expected outputs. The level of documented information needed depends on the organisation’s size, complexity and the importance of each process, but it must include the relevant processes and other documented information needed to deliver intended outcomes and comply with the chosen standard’s requirements.
-
Implement management system:
Clear communication and appropriate competence training are essential. During the implementation phase, you will work to ensure that your organisation operates in line with defined and documented processes. Once this is achieved, you can demonstrate the system’s compliance and effectiveness.

-
Select a certification body/registrar:
Selecting the right certification body or registrar can make a difference throughout your certification journey. DNV offers a trusted partnership approach, a risk-based approach and a range of free digital tools to help you manage your certification journey before, during and after the audit.
-
Consider a pre-audit gap analysis:
Consider a preliminary evaluation by your certification body or registrar to identify and correct non-conformities before starting the official certification process. The purpose is to identify areas of non-conformance or weakness, allowing you to address them before the official certification process begins.

ISO 50001 - FAQ
-
ISO 50001 is a voluntary international standard for energy management systems (EMS). It provides organisations of any size or sector with a structured approach to managing energy use and consumption.
The standard supports organisations in establishing an energy policy, identifying significant energy uses, and implementing action plans to improve energy performance. It offers a systematic framework to embed effective energy management practices and drive continual improvement across the organisation.
Built on ISO's Harmonized Structure (HS), ISO 50001 can be easily integrated with other management system standards, such as ISO 9001 and ISO 14001.
-
An energy management system based on the ISO 50001 standard helps organizations take a structured approach to understand, manage and improve their energy performance. A well-implemented energy management system helps organisations monitor and analyse energy data, assign clear roles and responsibilities, and integrate energy considerations into daily operations and longterm planning.
-
To achieve ISO 50001 certification, an organisation must first implement an energy management system that meets the requirements of the standard and then undergo an audit by an independent, accredited certification body such as DNV. If the management system is found to be compliant, certification is granted.
To maintain certification, the organisation must successfully complete annual surveillance audits and undergo recertification every three years.
