The Dawn of Sustainable Data Centers in the EU: A Closer Look at the New Rating Scheme

In an era where digital transformation is at the heart of economic and social evolution, the role of data centers — the backbone of internet services, cloud computing, and the broader Information and Communication Technology (ICT) sector — cannot be overstated. Yet, as the demand for digital services surges, so does the environmental footprint of these data centers, primarily through their substantial energy consumption and subsequent greenhouse gas emissions. Recognizing this, the European Union has taken a bold step forward by introducing a comprehensive rating scheme to enhance the sustainability of data centers across the Union.

A New Chapter for Energy Efficiency

As part of its ambitious European Green Deal and the quest for climate neutrality by 2050, the EU has unveiled a delegated regulation establishing the first phase of a common Union rating scheme for data centers. This move is not just about reducing carbon footprints; it's a strategic endeavor to enhance energy security, promote economic resilience, and lead by example in the global fight against climate change.

The regulation sets forth a framework requiring data centers with an installed information technology power demand of at least 500 kW to report a range of information and key performance indicators. These encompass energy consumption, power utilization, and renewable energy sources, among others. The goal is clear: to make data centers more energy-efficient, reduce their reliance on fossil fuels, and ultimately, significantly contribute to the EU's broader environmental objectives.

Implications for the Data Center Industry

This regulation marks a significant shift for data center operators across the EU. No longer can sustainability be an afterthought; it is now a regulatory requirement. Data centers are to report their energy performance and sustainability metrics annually, feeding into a European database that will serve as the basis for the new rating scheme.

This requirement is expected to drive innovation and investment in green technologies within the data center sector. Operators must explore more efficient cooling techniques, embrace renewable energy sources, and consider the potential for reusing waste heat. Moreover, the transparency by mandatory reporting could foster a competitive environment where operators are incentivized to improve their sustainability practices to achieve a better rating continuously.

The Road Ahead

While the initial phase focuses on reporting and establishing key performance indicators, future regulations will build on this foundation to enhance the scheme's robustness and impact. This progressive approach allows data center operators to gradually adapt to the new requirements, ensuring a smooth transition towards more sustainable operations.

The implications of this regulatory shift extend beyond the data center industry. By promoting energy efficiency and sustainability in one of the most energy-intensive sectors of the digital economy, the EU is setting a precedent that could inspire similar initiatives worldwide. It's a reminder that technological advancement and environmental sustainability must go hand in hand in the digital age.


The EU's new rating scheme for data center sustainability is more than a regulatory requirement; it's a call to action for the industry to align with the broader global energy efficiency and climate neutrality goals. As data centers adapt to these new standards, we can expect to see a ripple effect — not just in how data is stored and managed but in the overall approach to sustainable digital infrastructure development. The journey towards greener data centers is just beginning, and it promises to be a pivotal chapter in the EU's green transition.
