EU Proposes Data Center Energy Labels to Target Large Facilities

European Commission introduces labeling system for energy efficiency in major data centers, aiming to curb rising electricity use while capturing waste heat potential.

The European Commission proposed a classification system for data centers with installed IT power exceeding 500 kW, alongside a public consultation on minimum energy-efficiency standards closing December 2026. This follows estimated EU data center electricity consumption of 68 TWh in 2024, projected to rise to 114 TWh by 2030 due to AI workloads. The system includes plans for sustainability labels starting in 2027 and a review by late 2028. Crucially, the regulation does not require disclosure of electricity, water, or emissions under the classification framework.

The mechanism centers on labeling large data centers to track energy use, with the Commission estimating that recovering half the waste heat from EU facilities could supply heating for 4 million households. However, this potential depends on actual implementation of heat recovery systems.

This move addresses growing energy demands in digital infrastructure. If adopted, the standards could reduce the EU’s digital energy footprint for large facilities while creating a pathway to repurpose waste heat—a resource currently underutilized. The impact on cloud service costs remains unverified, as the measures do not mandate immediate efficiency improvements.

The next critical step is the consultation’s outcome, which will inform a legislative proposal expected in Q2 2027. The timeline assumes no objections from the European Parliament during the two-month scrutiny period required before potential entry into force. All consumption figures and projections are Commission estimates, and the classification applies only to data centers above 500 kW.
