Summary As proposed, the Cloud and AI Development Act (CADA) does not create new energy-efficiency standards; it requires the use of existing EU metrics for data centre sustainability. Article 11(1) would require Member States, when setting sustainability requirements for data centres in acceleration zones, to use the key performance indicators specified in Delegated Regulation (EU) 2024/1364 pursuant to the Energy Efficiency Directive, Directive (EU) 2023/1791 (Annex II, points (a) to (n)). This anchors the EU's data centre rating scheme inside CADA's acceleration-zone framework. CADA is a proposal and not yet in force.

Detail

The relationship between the proposed CADA and the Energy Efficiency Directive (EED) is structural rather than duplicative. CADA aims to accelerate data centre deployment; the EED and its implementing measures provide the metrics for measuring and improving energy efficiency. Rather than inventing new metrics, CADA would anchor its sustainability requirements in the existing EED framework for consistency.

The legal hook: Article 11(1) of CADA

The primary bridge is Article 11(1) of the CADA proposal, which provides:

"When setting sustainability requirements for data centres deployed in acceleration zones, Member States shall use the key performance indicators specified in Delegated Regulation (EU) 2024/1364 pursuant to Directive (EU) 2023/1791 under Annex II, from (a) to (n)."

For compliance officers, this means any data centre seeking the streamlined permitting of an acceleration zone would face sustainability requirements measured against specific KPIs — KPIs defined not in CADA itself but imported from the EED's implementing legislation.

The role of Delegated Regulation (EU) 2024/1364

Delegated Regulation (EU) 2024/1364 establishes the first phase of a common Union rating scheme for data centres and defines the methodology for calculating efficiency metrics. These commonly include indicators such as:

Power Usage Effectiveness (PUE): how efficiently a data centre uses energy, comparing total facility energy to IT-equipment energy.
Water Usage Effectiveness (WUE): water consumption relative to IT load.
metrics related to greenhouse-gas emissions; and
indicators for waste-heat recovery.

By referencing this delegated regulation, CADA would make the "sustainability requirements" in Article 11(1) quantifiable, auditable and harmonised across Member States, helping prevent a race to the bottom on environmental standards to attract investment.

Integration with acceleration zones

CADA introduces "data centre acceleration zones" (Article 10) — areas where deployment is facilitated through streamlined permitting and infrastructure planning. Article 11(1) makes clear that this acceleration would be conditional: Member States would designate zones, set sustainability requirements for data centres within them, and use the EED-derived KPIs from Delegated Regulation (EU) 2024/1364 to define those requirements. This creates a unified compliance pathway, so an operator does not navigate separate, conflicting sustainability regimes for CADA and the EED.

Strategic alignment and policy context

The explanatory memorandum highlights the synergy. As proposed, it notes that CADA contributes to the objectives of the Energy Efficiency Directive on guiding the data centre industry towards greater energy efficiency, but observes that, beyond transparency and reputational considerations, the EED "does not set incentives for data centre operators to improve their sustainability performance" and does not contain measures for accelerating the roll-out of sustainable data centres. CADA aims to fill that gap by linking sustainability compliance to participation in accelerated permitting. The memorandum also references the EU Code of Conduct on Data Centre Energy Efficiency, noting its limits relative to CADA's deployment-phase measures.

What this means for you

For in-house counsel and compliance officers in the cloud and data centre sector, the CADA/EED intersection has several practical implications:

Unified compliance framework: You would not need separate sustainability frameworks for CADA and the EED. Focus on the metrics in Delegated Regulation (EU) 2024/1364, ensuring your design and operations are measured against the KPIs in Annex II, points (a) to (n).
Acceleration-zone eligibility: To build in a designated zone, be prepared to demonstrate compliance with these KPIs during permitting. Failing the sustainability requirements defined by the EED metrics could disqualify a project from the streamlined procedures.
Monitoring and reporting: CADA does not impose direct reporting obligations on operators to the Commission, but Member States will likely require KPI-compliance evidence as part of the permit application, so ensure your monitoring can capture PUE, WUE and other relevant metrics.
Future-proofing: Because the referenced KPIs sit in EED implementing legislation, they may evolve. Track updates to Delegated Regulation (EU) 2024/1364, as these would directly affect your CADA acceleration-zone obligations.

Common misconceptions

CADA introduces new energy-efficiency standards. As proposed, it does not create new standards; it mandates the use of existing EED metrics via Delegated Regulation (EU) 2024/1364.
Only large data centres need to comply. Article 11(1) applies to sustainability requirements for data centres deployed in acceleration zones. Location within a designated zone and participation in the streamlined permitting matter more than facility size.
The EED rating scheme is voluntary under CADA. For data centres in acceleration zones, using these KPIs would be a requirement under Article 11(1) — a condition for benefiting from the accelerated framework.
