The European Commission’s Innovative Approach to Sustainable Data Centre Performance

Europe’s data centres are facing a new era of environmental accountability as the European Commission introduces a groundbreaking method to evaluate their sustainability amid a surge in demand for computing infrastructure.

Enhancing Transparency with a Common Rating Scheme

A novel common rating scheme is set to revolutionize the visibility into data centre sustainability by shedding light on their energy and water consumption, as well as their impact on the electricity system. This initiative targets data centres with over 500kW capacity and aims to support the expansion of Europe’s digital infrastructure while addressing the strain larger facilities pose on energy networks and natural resources.

The European Commission anticipates the rollout of the first sustainability labels on individual data centres by 2027. A review of the scheme’s effectiveness is scheduled by the end of 2028 to assess its functionality and potential need for adjustments.

Dan Jørgensen, Commissioner for Energy and Housing, underscores the importance of sustainable data centres, emphasizing the necessity of managing their energy consumption to align with the principles of digital transformation.

Addressing the Growing Data Centre Footprint

The proposal comes at a crucial time as the demand for computing capacity in Europe is on the rise. Data centres in the EU consumed approximately 68TWh of electricity in 2024, a figure projected by the International Energy Agency (IEA) to reach 114TWh by 2030, potentially constituting over 3% of the bloc’s total electricity demand. Artificial intelligence (AI) is identified as a significant driver behind this surge.

Simultaneously, the EU aims to expand its data centre capacity significantly, with the Commission targeting a threefold increase over the next five to seven years to bolster Europe’s technological independence and digital sovereignty. However, this growth may intensify electricity and water demand, strain electricity grids, and escalate carbon emissions.

Comprehensive Sustainability Metrics

The proposed sustainability framework for data centres transcends mere electricity consumption tracking. It encompasses energy and water usage metrics along with insights on how data centres interact with the electricity grid.

Key aspects of the rating system include waste heat recovery, clean energy generation, and grid flexibility. Data centres that can adapt their electricity usage in response to grid conditions can enhance grid stability and reduce operational costs. The Commission estimates that harnessing half of the waste heat produced by European data centres could satisfy the heating needs of four million households.

Teresa Ribera, Executive Vice-President for Clean, Just, and Competitive Transition, emphasizes the importance of transparency in rating large data centres based on their impact on the energy system, highlighting the role of efficient, flexible, and sustainable practices in fostering the EU’s energy transition.

Paving the Way for Sustainable Data Centres

The rating scheme development coincides with efforts to establish minimum performance standards for data centres. The Commission’s call for evidence and public consultation seeks input from Member States, industry stakeholders, and civil society to shape sustainable data centre development and foster markets for eco-friendly digital infrastructure and services.

The consultation period runs until December 14, 2026, with subsequent scrutiny of the delegated regulation in the European Parliament and Council. The focus is on accommodating Europe’s expanding digital infrastructure within its energy system while enhancing resource transparency.

Collaborative Efforts for a Sustainable Future

Beyond the rating scheme, the Commission collaborates with data centre operators, grid operators, energy providers, and public authorities to forge a tripartite agreement on data centres following a declaration of intent signed in June 2026. The overarching goal is to integrate Europe’s growing digital infrastructure into the energy system while promoting resource efficiency.

The proposed ratings offer a holistic view of data centres, emphasizing resource consumption and their interaction with energy networks. By prioritizing sustainability, data centres can become valuable assets in Europe’s energy transition.
