Most data centers refusing to say how much water, electricity they use

A new report shows most European data centers are not disclosing required electricity and water usage, despite EU reporting rules, creating a transparency gap just as cloud and AI workloads are sharply increasing demand. For CIOs and technology leaders, this raises strategic risk around regulatory compliance, ESG scrutiny, and access to constrained power and water resources, while also making it harder to plan capacity, negotiate with providers, and defend infrastructure decisions to the business. IT organizations will need tighter energy/water measurement, vendor accountability, and sustainability-aware architecture decisions as infrastructure consumption becomes a board-level operating issue.
