European Commission mandates energy and water efficiency disclosures for data centres in the EU

On September 21, 2026, the European Commission proposed regulations requiring data centres in the EU to disclose their energy and water efficiency. This initiative aims to address environmental concerns as data centre capacity is expected to triple in the next seven years. The new rules will apply to facilities with a capacity of 500 kilowatts or more, starting in 2027, and will include a labelling system to promote transparency and sustainability.
