EU will label data centres by energy and water efficiency
The EU unveiled a rating system requiring data centres above 500 kilowatts to disclose energy and water efficiency through electronic labels. The first labels are expected in 2027, while a 12-week consultation on minimum performance standards remains open until 14 December. The package aims to make pressure on grids, water and emissions measurable as Europe expands computing capacity.

One label for energy and water
The European Commission unveiled a rating system requiring data centres above 500 kilowatts to disclose energy and water efficiency through electronic labels. The label will cover more than facility resource use: it will also show local water stress and contributions to the energy system such as waste-heat reuse. The rating system forms the first measurement layer of a package intended to make the energy, water and carbon burden of data-centre growth more visible.[2]
Minimum standards enter consultation
The Commission also opened a 12-week public consultation on minimum performance standards for data centres. Responses are due by 14 December and will feed preparations for legislation planned for the second quarter of 2027. Reuters says the new label could precede mandatory floors for energy and water performance. At this stage, the label does not cap consumption; it creates a common basis for comparing measurements before the next rules are set.[1], [2]
Accounting for resources as capacity grows
The EU wants to triple data-centre capacity over the next seven years to support artificial intelligence and other digital services. Reuters reports that uncontrolled growth could strain electricity grids, deplete water resources and increase carbon emissions. The Commission likewise frames its consultation around energy consumption, grid effects, carbon and water use. That gives the label and standards work an economic role: resource costs associated with new capacity can be tracked through a common set of measures.[1], [2]
