5 Lessons learned about ISO 50001

As the deadline is approaching rapidly, many companies are already looking to prepare thoroughly. Yet the same question keeps coming up: where do you start, and how do you approach this in a structured way?

During a recent seminar we organized, an auditor and a company shared their experiences and practical insights. Here are five key lessons learned that we would like to highlight.

1. Focus on long-term objectives

We do not recommend working with annual targets. A long-term approach offers greater flexibility and is often more realistic. For example, aiming for a 30% reduction in energy consumption over three years is generally more achievable than committing to a 10% reduction every single year.

Failing to meet an annual target could put your accreditation at risk. By setting longer-term objectives, you reduce this risk while still maintaining a clear direction for improvement. Of course, targets can and should be adjusted along the way if circumstances change or new insights emerge.

In addition, make sure your KPIs are logical, relevant, and well-structured. Establish a clear method for reviewing them regularly and adjusting them when necessary—an important step that is often overlooked in practice.

2. Translate corporate objectives into the local reality

For companies with multiple sites, group-level objectives do not necessarily have to be adopted locally on a one-to-one basis. Each site has its own context, energy consumption profile, and improvement opportunities.

It is therefore perfectly acceptable to define site-specific, achievable objectives that reflect local realities. However, it is important to ensure proper internal alignment, identify potential risks, and involve the relevant stakeholders. In many cases, the corporate group sets the overall vision, while individual sites are responsible for translating that vision into concrete actions and targets.

3. Analyze not only deviations, but also successes

When monitoring performance, the focus is often placed on negative deviations. However, it is equally worthwhile to analyze your "golden runs"—periods in which outstanding results are achieved. These can provide valuable insights and best practices that can be applied elsewhere in the organization.

It can also be useful to examine data at a finer level of detail, such as 15-minute intervals. This often provides a clearer understanding of the factors that drive superior performance. In addition, make sure to share successes internally. Doing so allows other departments to learn from these achievements and contribute more effectively to the organization's energy objectives.

4. Build a strong multidisciplinary team

Do not make the implementation dependent on a single manager, but instead assemble a strong team of experts. Ideally, this team should consist of internal employees from different departments, complemented by an external energy manager.

This approach brings together expertise, creates internal support, and increases the chances of successful implementation. Moreover, a joint approach makes it easier to achieve more targeted impact among significant energy users.

Bonus tip: also establish a communication matrix. Define who communicates what, to whom, and through which channels.

5. Define a realistic scope for your management system

Carefully consider in advance which elements you want to include in your energy management system. The more specific and extensive your scope becomes, the more you will need to fully integrate it into your implementation and management processes. In practice, this level of detail is not always necessary.

Therefore, avoid unnecessary complexity and choose a clear and realistic focus. This keeps governance manageable and allows processes to be translated more efficiently into workable procedures and protocols. For example, it may be appropriate to exclude product transport from the scope, unless this is an activity directly managed by your own company.

Sustainability is everybody’s business
