Brussels grades EU data centers on numbers only 36% of them report
The Commission's A-to-G scheme covers every EU site above 500 kilowatts and enters force as a delegated regulation, with member states and the Parliament given two months to object and no power to amend. First labels come in 2027.

What happened
- The European Commission proposed on September 21, 2026 a common A-to-G scheme grading every EU data center above 500 kilowatts on energy efficiency, water use and clean-power sourcing, using the look of appliance labels.
- It arrives as a delegated regulation, in force without a vote by member states or the European Parliament, each of which gets two months to object to a text that neither can amend.
- A Commission report found that only 36% of EU data centers currently provide the required information, even though supplying it is already a prerequisite under EU energy rules.
- An internal Commission document reportedly suggested about one-fifth of Europe's data centers would receive ratings close to the very bottom of the scale.
- The European Data Centre Association warned in April that the requirements could discourage investment in AI.

Why it matters
- constraint Tripling computing capacity while consumption stops at 114 TWh requires energy per unit of capacity to fall about 44%. Any EU siting plan is costed against that number.
- decision Because the grade is produced automatically from each operator's own annual submission, filing turns into a decision about which letter is attached to the site.
- contradiction Jorgensen's 2.5% and the IEA's above-3-percent reconcile only if total EU electricity demand climbs roughly 40% by 2030.
- exposure Should the bottom-rated fifth of sites sit inside the minority that file, they are 56% of graded sites, so the operators that comply take the visible downside first.
Brussels wants three times the computing capacity on a fraction more electricity. EU data center consumption is projected to run from about 68 TWh in 2024 to 114 TWh in 2030, which the Commission describes as nearly a doubling; 114 divided by 68 is 1.68 [5][6][1]. The bloc is at the same time trying to triple its computing capacity [4]. Teresa Ribera, the Commission's executive vice-president for Clean, Just and Competitive Transition, said the EU cannot triple data-center capacity while putting the same level of pressure on its grids, water resources and energy bill [17].
Two of the percentages do not sit easily together. Energy Commissioner Dan Jorgensen put data centers at about 2.5 percent of Europe's electricity use, and 68 TWh at 2.5 percent implies a continental total near 2,720 TWh, against which 114 TWh is 4.2 percent [7][3]. One figure is quoted for Europe and the other, the International Energy Agency's above-3-percent, for the EU, so some of the gap is definitional [5][6][7].
The letter is not only about kilowatt-hours. The rating takes in whether a facility can reuse the heat it produces, and the scheme credits operators for waste heat recovery, added clean capacity and shifting electricity demand when the system needs it [3][18]. The Commission estimates that reusing about half of the waste heat generated by Europe's data centers would provide enough heating for 4 million households [9].
Sixty-four percent of EU data centers do not supply the information the ratings need [5]. First labels are expected in 2027 [2], and counting two months from the 21 September proposal puts the objection deadline around 21 November [6]. Jorgensen described the proposal as a way to work with the industry and not as punishment, and said technology companies should see regulation as an "opportunity" to build greater public support [16].
A letter grade costs a tenant nothing until someone prices it into a lease. I'd expect the coverage rate, then, to decide whether any of this constrains European siting before 2028, since a label generated from a filing can only describe an operator that filed [10]. Two things would cut against that. Filing could jump sharply once the output is a graded letter rather than a spreadsheet nobody reads, or an objection inside the window could send the text back [6]. The European Data Centre Association argued in June that AI ambitions should take priority over climate targets [14]. Jorgensen told POLITICO that Australia and Singapore already use systems to rate data-center efficiency, and claimed the EU's proposal takes a more extensive approach [8].
What to watch
- Whether Parliament or member states lodge an objection before the window closes in late November, given that rejection is their only option.
- The coverage rate printed on the first 2027 labels: a jump above 36% would mean the filing duty finally bit.
- Whether the European Data Centre Association's June position on AI over climate targets shapes any objection to the text.
