EU Launches Sustainability Label for High-Power Data Centres
By Drooid · · How we work
Core Event
Starting on September 21, the European Commission will award an electronic sustainability label to data-centre facilities in the EU that have an installed capacity of more than 500 kW and that report under the bloc’s existing energy-efficiency rules. The label is intended to make power and water use, as well as electricity sourcing, comparable across sites and to inform procurement of more sustainable digital services. The move aligns with the EU’s goal of tripling data-centre capacity by 2035 while addressing a growing electricity demand that currently accounts for about 2.5 % of EU consumption.
Official Statements & Responses
The Commission explained that the rating scheme is meant to increase transparency and serve as a resource for better policymaking. A Commission official noted that, although mandatory reporting has been required since 2023, compliance has risen to roughly 50 % of eligible facilities. Enforcement, however, remains the responsibility of individual member states. The Commission also signaled that minimum-performance standards—effectively a floor for energy and water efficiency—will be introduced in 2027, with the possibility of eventually becoming mandatory. The label can recognise low-emission electricity sources, including nuclear, and the Commission is exploring whether data centres might provide grid flexibility or waste-heat supply to up to four million European homes.
Criticism & Opposition
Bram Vranken, a researcher and campaigner at the watchdog Corporate Europe Observatory, criticised the influence of large U.S. tech firms on the rule-making process. He argued that a confidentiality clause retained by Microsoft in the label’s design makes verification of the information difficult and could allow high-scoring facilities to conceal substantial power consumption. Vranken warned that a Google-rated data centre could still consume an “undisclosed gigawatt of power” without proper disclosure.
Data & Statistics
In 2024, European data centres used 68 terawatt-hours (TWh) of electricity; the Commission projects this will rise to 114 TWh by 2030, representing about 3.2 % of the bloc’s total electricity demand. Reporting compliance improved from roughly one-third of facilities in the first year of mandatory reporting to an estimated 50 % in the most recent period.
What’s Next
The Commission will publish the detailed minimum-performance standards in 2027, after a “probation time” that gives industry, including Microsoft—who in a July 2026 submission supported clean-power and efficiency indicators while seeking changes to water-efficiency bands—an opportunity to shape the final parameters. The forthcoming standards could eventually become binding, further tightening the EU’s sustainability framework for data-centre operations.
