The EU will force data centers to disclose how much water and energy they are using

Data centers will get a label, just like your fridge or dishwasher Energy and water consumption must be reported by 500kW+ sites The EC also wants to know how resources are being balanced in relation to local strains The European Commission has proposed a new rating scheme for data centers in a bid

Over the next seven years, the EU wants to triple its data center capacity, per <a href="https://www.reuters.com/business/environment/eu-require-data-centres-disclose-energy-water-efficiency-2026-09-21/" target="_blank"><em>Reuters</em></a><em> </em>reporting.</p><p>Importantly, the changes won't happen overnight with the rating scheme subject to a two-month scrutiny window, the Commission detailed. Still, the first ratings are set to go live as early as this year, and by the end of 2028, the EU hopes to have reviewed just how effective those new enforcements were.</p><p>"Understanding their energy and resource consumption is the essential first step towards integrating them sustainably into our energy system," Energy and Housing Commissioner Dan Jørgensen added.</p><figure class="van-image-figure pull-right inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:676px;"><p class="vanilla-image-block" style="padding-top:31.51%;"><img id="diM9tpwF2Lz85R8q85CT78" name="tr-g_news" alt="Google logo on a black background next to text reading 'Click to follow TechRadar'" src="https://cdn.mos.cms.futurecdn.net/diM9tpwF2Lz85R8q85CT78-1920-80.jpg" mos="" align="right" fullscreen="" width="676" height="213" attribution="" endorsement="" class="pull-rightinline"></p></div></div></figure> </article> ]]>
