Brussels Kept in the Dark Over Data Centre Power and Water Use

A formal legal complaint has been lodged against the European Commission, accusing the EU’s executive arm of failing to disclose the environmental footprint of data centres operating across the bloc. According to the filing, the Commission has kept key figures regarding the energy and water consumption of these facilities hidden from public view. The complaint asserts that withholding this information directly breaches established legal rules guaranteeing citizens the right to access environmental data held by public authorities.

Data centres form the physical backbone of the digital economy, housing the servers that power cloud computing and artificial intelligence. However, operating these industrial facilities requires immense volumes of electricity and large amounts of water for cooling. For citizens, understanding the volume of resources consumed by these sites is essential for evaluating their strain on local power grids, public water supplies, and climate targets. When official figures are kept behind closed doors, communities and independent observers are left unable to assess the real-world costs of Europe's digital expansion.

In the EU capital, transparency is an executive's favourite virtue right up until someone asks to see the spreadsheets. The European Commission frequently champions public openness, yet requests for raw administrative data regularly run into legal exceptions, trade secret arguments, and extensive redactions. This complaint targets the gap between official rhetoric and institutional practice. Within the Brussels machinery, a formal transparency challenge forces the executive to defend its information-gathering and disclosure practices, exposing the ongoing institutional tension between protecting commercial interests and honouring environmental governance rules.

The filing places the European Commission under pressure to address the allegations of transparency breaches. Executive officials must now determine whether to release the withheld environmental data on data centre energy and water usage or construct a formal legal defence for keeping it private. Should the Commission maintain its refusal, the dispute may escalate to oversight bodies such as the European Ombudsman or proceed to formal litigation before the EU courts.
