The EU proposes new regulations that require data centers with a capacity of 500 kW or more to disclose their energy and water efficiency. The disclosure will use an EU-designed labelling system that rates performance on standardized metrics. The rules aim to increase transparency and encourage more efficient operation of large data-center facilities.
