Introduction
Fortunately, there are many people, companies and organizations who want to act sustainably, ultimately it starts with yourself. Unfortunately, this is really not enough, we cannot escape the fact that regulation is needed to get a more sustainable world. Without regulation, we will never become sustainable enough. I am therefore a supporter of regulations on sustainability, however, it is important that the regulations are correct and enforceable.
With the huge growth and incredibly large impact that data centers can have in areas such as energy, regulatory compliance is vital. Besides regulation, transparent insight into data is key. What exactly are we talking about, where can we do better and what can we learn from others. More importantly, is the company you want to do business with as sustainable as they say they are?
This is therefore the reason why more and more insight into a company is needed, and the EU Taxonomy is a great example who to get more insights. Also data centers want to comply with the EU Taxonomy. One of the requirements for the EU Taxonomy is that the data center will be audited on the “EU Code of Conduct for data centers best practices”.
When this article refers to the EU Code of Conduct, it may also refer to a similar document such as the CLC/TR 50600-5-1.
The CLC/TR 50600-99-1 Recommended Practice has been withdrawn since the publication of the CLC/TR 50600-5-1.
What are the EU Taxonomy, EU Code of Conduct and the ISO 50001
EU Taxonomy
The EU taxonomy is a cornerstone of the EU’s sustainable finance framework and an important market transparency tool. It helps direct investments to the economic activities most needed for the transition, in line with the European Green Deal objectives. The taxonomy is a classification system that defines criteria for economic activities that are aligned with a net zero trajectory by 2050 and the broader environmental goals other than climate.

EU Code of Conduct
The Data Centres Energy Efficiency Code of Conduct has been established in response to increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply security impacts. The aim is to inform and stimulate data centre operators and owners to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres. The Code of Conduct aims to achieve this by improving understanding of energy demand within the data centre, raising awareness, and recommending energy efficient best practice and targets.

The EU Code of Conduct for data centers is a framework to identify opportunities in data centers, a collection of best practices which was not meant and developed as an auditing framework, there is also no certification possible.
ISO50001 Energy Management
ISO 50001 is based on the management system model of continual improvement also used for other well-known standards such as ISO 9001 or ISO 14001. This makes it easier for organizations to integrate energy management into their overall efforts to improve quality and environmental management.
ISO 50001 provides a framework of requirements for organizations to:
- Develop a policy for more efficient use of energy
- Fix targets and objectives to meet the policy
- Use data to better understand and make decisions about energy use
- Measure the results
- Review how well the policy works, and
- Continually improve energy management.

The EU Code of Conduct best practices consists of more than 100 possible areas of improvement which not only need to be checked but it must also be supported by evidence. Many data centers already comply to a large extent with the EU Code of Conduct, this is because it is in the interest of the data center organization to have a low Power Usage Effectiveness(PUE). This document does not elaborate on PUE; for more information on this, please refer to ISO/IEC 30134-2
A lot of energy can be saved with a low PUE. Customers therefore expect a data center organization to have a process in place for continuous PUE improvement.
At a PUE of 1.6, around 63% of the total energy can be usefully consumed by IT, at a PUE of 1.2 around 83% of the total energy can be usefully consumed by IT, this is a gain of 20%.
Initially, applying the Taxonomy and thus the EU Code of Conduct seems a logical step but is this really the case? Isn’t it perhaps a lot of unnecessary work for data center organizations to collect all the evidence, a burden that also results in well-trained technical staff mainly supporting compliance rather than actually implementing projects that lead to more energy savings and sustainability?
However, the question is why EU taxonomy requires data centers to be assessed against the EU Code of Conduct or a similar document, especially obtaining and providing evidence takes a very long time, rather than going through a checklist. Many parts of the EU Code of Conduct have been applied for many years, simply because it is the logical thing to do, no evidence of each best practice has been recorded before.
ISO/IEC 30134 Data Centers | Key Performance Indicators
As a data center industry, we do want to provide insight, so for many years several Data Centre Key Performance Indicators have been included as an international standard, the ISO/IEC 30134. More and more regulations refer to this ISO/IEC 30134, it is even quite possible that the data center industry is leading the way with these KPIs which can be used to determine and share the efficiency of various things. These include the PUE, WUE, CUE, ERF, REF, CER, ITEU, ITEE.

The most well-known KPI is the PUE which gives a good insight into the energy efficiency of the data center infrastructure which is the energy required so that the IT equipment is 24×7 available. An example of the data center infrastructure would be for example the cooling installations.
However, the PUE is a number at a given time, or, say, over a whole year, and the question, of course, is how this number compares with the past and the future. Has the PUE improved and what other opportunities are there to keep improving it.
It therefore makes sense for a data center organization to apply the EU Code of Conduct best practices, however, the question is whether each individual component should be audited or not.
Many data centers are already audited on their PUE within the ISO 50001 Energy Management program which can be seen as a much more efficient way.
Conclusion
A vast majority of data centers have already applied ISO 50001 Energy Management based on PUE. With the ISO 50001, new targets are set continuously, there is a process instead of continuous improvement.
The ISO 50001 is a process for continuous improvement, which is why not every organization is open to it. It may be that an organization can make huge gains with one optimization project and barely make any savings the following year. The aim of the ISO 50001 is to apply continuous improvement when there is room for improvement; it is about ensuring that companies do not come to a standstill in terms of energy savings.
So why do we still need the review of the EU Code of Conduct for data centers?

In this overview, PUE is the only one mentioned of the entire ISO/IEC 30134 series. The reason is that this PUE has the most similarities with the ISO 50001. However, there are more very meaningful KPIs in the ISO/IEC 30134, see the Datacenter Jedi Standards for this

9 个月Less than 5% of data centre and colocation providers I have assessed in the last 18 months were able to share the metrics specified by ISO30134. At best they had PUE, but even then it was annually calculated and reported at a DC level, making it mostly meaningless. Then there’s the impossibility of customers in colocation getting automated reporting out of providers! It’s pretty weak to be frank and the industry needs to stop pretending and start acting like they are taking responsibility
