Summary The proposed Cloud and AI Development Act (CADA) does not invent new energy efficiency metrics; instead, it anchors the rapid deployment of data centres to the EU's existing regulatory framework. As proposed, CADA requires Member States to apply the key performance indicators (KPIs) from Delegated Regulation (EU) 2024/1364 when setting sustainability conditions in designated "data centre acceleration zones." The proposal explicitly incentivises energy-efficient infrastructure by streamlining permits and offering strategic project status to facilities that meet high environmental standards, ensuring that capacity expansion aligns with the Energy Efficiency Directive (EED) and the EU Code of Conduct on Data Centre Energy Efficiency.

Detail

The Cloud and AI Development Act (CADA), as proposed in COM(2026) 502 final, addresses a critical tension in the EU's digital strategy: the urgent need to triple data centre capacity to support AI and cloud sovereignty versus the imperative to meet climate goals. The proposal resolves this not by imposing a parallel set of technical energy standards, but by mandating the use of the Union's established energy-rating scheme as the baseline for all accelerated deployment.

The Mandate: Acceleration Zones and Existing KPIs

A cornerstone of CADA is the creation of "data centre acceleration zones" (Article 10). These are specific geographic areas where Member States must designate sites for data centre deployment, aiming to reduce permitting times and ensure access to energy and connectivity. However, the proposal is explicit that acceleration does not equate to deregulation regarding environmental impact.

Article 11(1) establishes the critical link to existing energy law. It states:

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

This provision is legally significant. It prevents Member States from creating fragmented, national sustainability criteria that could distort the single market. Instead, it forces a harmonised approach where the "sustainability" of a data centre in an acceleration zone is measured strictly against the KPIs defined in the Energy Efficiency Directive (EED) framework. Delegated Regulation (EU) 2024/1364 establishes the first phase of the common Union rating scheme for data centres, covering metrics such as Power Usage Effectiveness (PUE), Carbon Usage Effectiveness (CUE), and Water Usage Effectiveness (WUE).

By embedding this reference directly into the text of CADA, the proposal ensures that the "fast-track" permitting process is conditional upon adherence to the highest available EU environmental standards.

The Legislative Gap: Why CADA is Needed

The explanatory memorandum and the recitals of the proposal clarify why this legislative intervention is necessary, distinguishing CADA from existing voluntary or operational frameworks.

The explanatory memorandum of the proposal addresses the relationship with the Energy Efficiency Directive. It acknowledges that the Directive "contributes to the objectives of the Energy Efficiency Directive on guiding the data centre industry towards greater energy efficiency." However, it identifies a structural gap: the Directive, while setting transparency and reputational standards, "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 across the EU or increasing related investment."

In other words, the EED tells operators how to measure efficiency, but it lacks the "carrot" of accelerated deployment or the "stick" of mandatory deployment conditions for new capacity. CADA fills this void by making the EED's metrics a prerequisite for accessing the acceleration zones.

The explanatory memorandum further clarifies the distinction between CADA and the EU Code of Conduct on Data Centre Energy Efficiency. It notes that the Code of Conduct "does not concern measures to deploy a data centre, instead focusing fully on practices for operating one." This is a crucial distinction for stakeholders. The Code of Conduct is a voluntary best-practice framework for existing facilities. CADA, conversely, targets the creation of new capacity.

The proposal states that it "provides measures to incentivise the roll-out of energy-efficient data centres, aligning with the Strategic roadmap for digitalisation and AI in energy." By referencing the rating scheme developed under the EED, CADA ensures that the new infrastructure built to meet AI demand is "sustainable by design," rather than retrofitting efficiency onto legacy or hastily built facilities.

Strategic Projects: Incentivising Innovation and Sustainability

Beyond the baseline requirements for acceleration zones, CADA introduces a tiered incentive mechanism for "strategic projects" under Article 14. The Commission may designate specific data centre projects as strategic if they meet certain criteria, unlocking potential support measures and further streamlined procedures.

One of the explicit criteria for this designation, found in Article 14(1)(b), is that the project "includes highly sustainable or innovative features, including technologies and solutions developed under Title II."

Title II of CADA establishes the "Cloud and AI Leadership Initiatives," which specifically target the development of next-generation, resource-efficient technologies. These include:

  • Advanced cooling and waste heat recovery systems.
  • Integration of data centres with energy grids (e.g., using small modular reactors or clean hydrogen).
  • AI-powered technologies for server efficiency and dynamic workload management.

By linking the "strategic project" status to these sustainability features, CADA creates a direct financial and administrative incentive for operators to go beyond the baseline KPIs. A project that merely meets the EED rating scheme might qualify for an acceleration zone, but a project that pioneers new efficiency technologies could qualify for strategic designation, potentially accessing EU funding or preferential permitting.

Alignment with Grid Planning and Energy Supply

The proposal also recognises that energy efficiency cannot be achieved in isolation from energy supply. Article 10(2) requires Member States to conduct comprehensive analyses of energy needs for acceleration zones, ensuring that network development plans account for future data centre demand. This aligns with the broader goal of the EED and the Digital Networks Act to ensure that grid capacity keeps pace with digital demand.

Furthermore, Article 10(1)(b) mandates that Member States consider "the available and future power grid capacity and the possibility and conditions for on-site storage and clean energy generation" when designating acceleration zones. This ensures that the "acceleration" of data centres does not lead to grid congestion or reliance on fossil-fuel peaking plants, but rather drives the development of clean energy infrastructure.

Implications for Public Procurement and Sovereignty

While CADA's primary focus on energy efficiency is in the deployment phase (Title III), its implications extend to the sovereignty framework (Title IV). Although the procurement rules in Article 30 focus on Union assurance levels (sovereignty), the underlying infrastructure must still comply with the sustainability requirements of Article 11 if located in an acceleration zone.

For public authorities procuring cloud services, this means that the "sovereign" cloud they are mandated to buy must also be "sustainable" by the EED standard. The proposal ensures that the push for a sovereign cloud ecosystem does not come at the expense of the EU's green transition. A provider cannot claim to be a "sovereign" option if their infrastructure fails to meet the KPIs of Delegated Regulation (EU) 2024/1364 in the zones where they operate.

What this means for you

For data centre operators, investors, and public-sector planners, the intersection of CADA and energy efficiency rules represents a shift from voluntary compliance to mandatory, harmonised standards for new capacity.

  1. Adopt the EU Rating Scheme Immediately: If you are planning a new data centre in the EU, do not wait for CADA to be fully adopted. The proposal mandates the use of the KPIs in Delegated Regulation (EU) 2024/1364. Your design and construction plans should already be benchmarked against these metrics (PUE, CUE, WUE) to ensure eligibility for future acceleration zones.
  2. Target "Strategic Project" Status: For large-scale investments, aim to qualify as a "strategic project" under Article 14. This requires demonstrating "highly sustainable or innovative features." Investing in advanced cooling, waste heat reuse, or on-site clean energy generation is not just good for the environment; it is a strategic pathway to faster permitting and potential EU support.
  3. Engage Early with Grid Operators: Article 10 requires a deep analysis of energy needs and grid capacity. Engage with transmission system operators (TSOs) and distribution system operators (DSOs) early in your planning process. Your project's viability in an acceleration zone will depend on the availability of clean energy and grid capacity, as mandated by the proposal.
  4. Differentiate Deployment from Operations: Understand that CADA targets the deployment phase. If you are operating an existing facility, the EU Code of Conduct remains your primary voluntary framework. However, if you are expanding or building new capacity, CADA's mandatory reference to the EED rating scheme will apply.
  5. Monitor Secondary Legislation: While CADA references the existing Delegated Regulation (EU) 2024/1364, the Commission is empowered to update Annex II and III of CADA via delegated acts to reflect technological progress. Stay informed on updates to the rating scheme, as the definition of "sustainable" may evolve.

Common misconceptions

"CADA creates a new, separate set of energy efficiency standards."

  • Reality: CADA does not invent new metrics. It explicitly mandates the use of the existing key performance indicators from Delegated Regulation (EU) 2024/1364, which implements the Energy Efficiency Directive. It integrates these existing standards into the deployment framework.

"Acceleration zones are 'green zones' where environmental rules are waived."

  • Reality: Acceleration zones streamline permitting procedures (e.g., reducing the 12-month limit for permits), but they do not waive environmental requirements. Article 11 explicitly requires Member States to apply the strictest EU energy KPIs when setting conditions in these zones. The goal is to accelerate sustainable deployment, not to bypass climate rules.

"The EU Code of Conduct on Data Centre Energy Efficiency is the main tool for new data centres under CADA."

  • Reality: The Code of Conduct focuses on operating existing data centres. The explanatory memorandum clarifies that it does not cover deployment. CADA fills this gap by providing the regulatory framework and incentives for building new, energy-efficient facilities, using the EED rating scheme as the benchmark.

"Only large hyperscalers need to worry about these energy rules."

  • Reality: The requirement to use the EU rating scheme applies to any data centre deployed in an acceleration zone, regardless of the operator's size. As public authorities increasingly procure from a diverse range of providers, including SMEs and specialized sovereign cloud providers, the sustainability of their underlying infrastructure will be a regulated criterion for deployment.
