The European Commission has proposed a common efficiency label for larger data centres as demand for AI and cloud computing grows. Facilities with capacity above 500 kilowatts would report information on energy and water use, including how water consumption relates to local scarcity. The proposal prioritises transparency, not immediate limits on consumption.
Key takeaways
The planned labels are intended to make data centres easier to compare as Europe expands its digital infrastructure. Key details include:
- Data centres above 500 kilowatts would report energy and water efficiency information.
- The first facility-level labels are expected in 2027, subject to the EU process.
- The proposal does not initially cap electricity or water use or require disclosure of total power consumption.
- The Commission is also exploring minimum performance standards, potentially for 2027.
Rising demand puts infrastructure under pressure
The EU wants to triple data centre capacity over the next five to seven years to support AI and strengthen its digital independence. Meanwhile, electricity use by European data centres reached about 68 terawatt-hours in 2024. The Commission projects it could rise to 114 TWh by 2030—more than 3% of total EU electricity demand.
The proposed label would track more than resource efficiency. It could also show whether operators reuse waste heat, produce clean energy or adjust electricity consumption to help support the grid. These measures could make facilities more useful to surrounding communities and energy systems, rather than treating them only as major consumers.
Transparency comes before limits
The Commission’s proposal is a disclosure measure, not a consumption cap. It would not initially require operators to reveal their total electricity use, according to reporting on the plan. Lawmakers have two months to object to the delegated regulation before it can take effect, while the Commission is consulting on possible minimum performance standards.
The distinction matters: comparable reporting may help governments, businesses and local communities assess projects, but its value depends on complete, verifiable data. Reporting under existing EU requirements has been incomplete, with preliminary results reaching around 50%, according to a Commission official cited in media reports. That leaves a practical question for policymakers: how will reported figures be checked and enforced?
Local impacts and AI procurement
Water use can be particularly consequential in regions facing scarcity, where standardised disclosures could give local officials and residents a clearer view of a nearby facility’s demands. The Commission has also said that reusing around half of data centres’ waste heat in Europe could meet the heating needs of four million households, although delivering that benefit would depend on suitable local infrastructure.
For Power AI Media readers tracking both AI’s practical growth and its wider social impacts, the proposal connects infrastructure choices to environmental costs. There is no immediate change for everyday users, but efficiency information may influence where companies build and which cloud or AI providers customers choose. As labels and possible standards develop, energy and water performance could become a more prominent part of technology procurement—not just corporate sustainability reporting.
