EU Implements New Sustainability Rating Scheme for Data Centres

This regulation aims to enhance transparency and sustainability in a sector projected to consume a significant portion of the EU's energy.

• On September 21, 2026, the European Commission proposed a common sustainability rating scheme for data centres.
• Facilities with IT power demand over 500 kW will be required to disclose energy and water consumption metrics.
• The first sustainability labels are expected to be issued in August 2027, following a two-month scrutiny period.

• Data centre electricity demand is set to rise sharply, from 68 TWh in 2024 to 114 TWh by 2030, accounting for 3% of total EU demand.
• The EU is balancing digital growth with climate goals, aiming to triple data centre capacity without straining energy resources.
• Previous regulations have established reporting requirements, laying the groundwork for this new rating scheme.

The European Commission's recent Delegated Regulation establishes a common rating scheme for data centres, a critical step in addressing the growing energy demands of the digital economy. As artificial intelligence (AI) technologies proliferate, the electricity consumption of data centres is projected to surge, necessitating a structured approach to sustainability. The regulation mandates that data centres with an installed IT power demand exceeding 500 kW disclose key performance indicators (KPIs) related to energy use, water consumption, renewable energy factors, waste heat reuse, and grid flexibility.

This initiative is not merely about compliance; it reflects a broader strategy to integrate sustainability into the EU's energy framework. By introducing electronic A-to-G sustainability labels, the EU aims to create a transparent marketplace where consumers and businesses can make informed decisions based on environmental performance. The labels will be automatically generated through a centralized EU database, streamlining the reporting process for data centre operators.

The regulation is part of a larger effort to ensure that the digital transformation driven by AI does not exacerbate existing pressures on the energy grid. The EU's commitment to sustainability is evident in its previous steps, including the 2024 Delegated Regulation that established initial reporting requirements. This new scheme builds on that foundation, emphasizing the need for data centres to adopt more efficient practices and technologies.

As the scrutiny period unfolds, stakeholders are encouraged to participate in a public consultation on minimum performance standards, which will inform future legislative proposals. This engagement is crucial, as it allows market participants to voice their concerns and expectations regarding the implementation of these standards. The outcome of this consultation will likely shape the regulatory landscape for data centres in the coming years.

In summary, the EU's sustainability rating scheme represents a significant shift towards accountability and efficiency in the data centre sector. As the first labels are set to roll out in 2027, operators will need to prepare for mandatory reporting and potential upgrades to meet the new standards. This proactive approach not only addresses environmental concerns but also positions the EU as a leader in sustainable digital infrastructure.

• Data Centre Operators: Must adapt to new reporting requirements and potentially invest in efficiency upgrades.
• Investors: Need to reassess the financial viability of data centres based on new sustainability metrics.
• Regulatory Bodies: Will oversee compliance and enforcement of the new standards.
• Consumers: May benefit from increased transparency and potentially lower energy costs as efficiency improves.

• Implementation of the sustainability labels: The rollout in August 2027 will reveal how well data centres adapt to the new standards.
• Public consultation outcomes: Feedback on minimum performance standards will shape future regulations and compliance requirements.
• Market response: Watch for shifts in investment patterns as stakeholders adjust to the new sustainability landscape.
