Should data centres be required to publicly disclose their energy and water usage efficiency?
On 21 September 2026, the European Commission adopted a regulation creating a uniform EU-wide rating system for data centres. The move establishes a standardized method to track energy and water efficiency across the industry.
Why it matters
Rising electricity consumption from data infrastructure, projected to reach 114 TWh by 2030, prompted the commission to implement transparent reporting. This system allows for objective comparisons of environmental performance between facilities.
Facilities with at least 500 kW of IT power must report metrics, including PUE ratios where 1.15 qualifies as class A and above 1.9 as class G. Water usage efficiency is also rated, with 0.1 litres per kWh or less required for an A rating.
The players
European Commission
This is the executive branch of the European Union responsible for proposing legislation and implementing decisions.
The details
Data centres are required to submit annual usage data to a central database, which will generate an efficiency label valid for one year. Operators are obligated to provide these electronic labels to any person upon request.
Timeline
2024: Data centres consumed approximately 68 TWh of electricity.
21 September 2026: The European Commission adopted the delegated regulation.
14 December 2026: The deadline for consultation on minimum performance standards.
Q2 2027: The European Commission plans to propose minimum performance standards.
15 August 2027: The database begins generating official efficiency labels.
The Tech Race
This regulation formalizes environmental accountability in a sector previously lacking unified transparency standards. It positions the EU to lead in digital infrastructure governance as the industry accelerates its shift toward energy-efficient operations.
Consumers and stakeholders gain access to verifiable efficiency data, allowing them to assess the environmental footprint of digital services. Operators must now maintain digital records to ensure compliance and satisfy public information requests.
The takeaway
This system provides a standardized benchmark for tracking infrastructure sustainability in a growing digital economy. Organizations operating large facilities should prepare for upcoming minimum performance mandates by optimizing their current PUE and WUE ratios.
What happens next
The European Commission is scheduled to propose minimum performance standards for data centres in the second quarter of 2027, following a consultation period ending 14 December 2026.
