Summary As proposed, the Cloud and AI Development Act (CADA) would shift much of the environmental assessment for data centres in acceleration zones from the individual project to the zone level. Under Article 13(3), before issuing the zone's aggregated baseline permit, the Member State must carry out all necessary procedures and assessments, including any relevant environmental assessments, at the level of the acceleration zone. Individual operators would then need additional permits only for activities falling outside that baseline permit (Article 13(4)), streamlining deployment.

Detail

The Cloud and AI Development Act (CADA) proposes to move environmental permitting for data centres in designated "data centre acceleration zones" from a project-by-project model toward a zone-level approach, to reduce the administrative delay that currently slows deployment of computing capacity in the EU.

The aggregated baseline permit

The centrepiece is the "aggregated baseline permit." As proposed, Article 13(2) requires Member States to prepare and issue, for each designated acceleration zone, an aggregated baseline permit authorising data centre deployment in that zone. That permit covers the permits and administrative authorisations required for data centre projects located within the zone, excluding installation-specific permits.

The purpose is to pre-clear the generic environmental and planning impacts of hosting data centres in a given area, removing redundant administrative steps for individual operators. (Note that Recital 41 of the proposal additionally states that the aggregated baseline permit should exclude grid connection permits; the operative text of Article 13(2) expresses the carve-out as installation-specific permits.)

Zone-level environmental assessments (Article 13(3))

The key procedural change is in Article 13(3), which as proposed states:

"Before issuing the aggregated baseline permit referred to in paragraph 2, Member States shall carry out all necessary procedures and assessments, including any relevant environmental assessments, planning procedures and evaluations applicable at the level of the acceleration zone."

This requires the relevant assessments to be conducted by the authorities before the baseline permit is issued, considering the impacts at the level of the zone rather than of a single facility. This connects with Article 10(3), under which, where spatial and development plans are subject to assessment under the Strategic Environmental Assessment Directive (2001/42/EC) and Article 6 of the Habitats Directive (92/43/EEC), those assessments must be combined — and, where applicable, must also address impacts on water bodies under Directive 2000/60/EC.

Because these assessments are completed at zone level, they are not repeated for each subsequent data centre project built within the zone, provided the project stays within the parameters of the baseline permit.

Installation-specific assessments

The zone-level assessment does not eliminate all requirements for individual operators. As proposed, Article 13(4) states:

"Data centres deployed in acceleration zones shall be required to obtain additional permits only for activities falling outside the aggregated baseline permit referred to in paragraph 2."

So a facility whose activities, technologies or scale were not covered by the zone-level assessment would still require separate, installation-specific permitting. For example, a novel cooling technology with environmental risks not addressed in the zone study, or a facility exceeding the parameters assumed at zone level, would trigger additional authorisation.

Article 13(1) provides that data centre projects deployed in acceleration zones "shall be considered as strategic projects within the meaning of Article 14 of Regulation (EU) 2026/XXX [on speeding-up environmental assessments]" and benefit from the toolbox set out in the Annex to that Regulation — so any remaining installation-specific assessments also benefit from that accelerated framework.

Timeline and efficiency

As proposed, Article 13(5) requires that administrative applications for the planning, construction and operation of data centres in acceleration zones be processed efficiently, transparently and in a timely manner, and that the permit-granting procedure not exceed 12 months from submission of a comprehensive application (without prejudice to shorter national time limits). Where national law provides such a status, projects are to be allocated the status of highest national significance — though the proposal does not oblige Member States to introduce that status.

Strategic-project designation

The zone-level approach works alongside the separate strategic-project mechanism in Article 14, under which the Commission may designate projects meeting at least two of five criteria (for example, supporting essential public-sector functions, including highly sustainable or innovative features, supporting grid stability, integrating Union-designed chips, or addressing a major capacity shortage). That designation can bring additional support measures, but it is distinct from the zone-level environmental clearance.

What this means for you

For in-house counsel and compliance officers overseeing data centre development, the proposal could reduce time-to-market, but requires care.

1. Verify zone designation and baseline-permit status. Before committing capital, confirm the site sits in a formally designated acceleration zone and that the Member State has issued the aggregated baseline permit. Article 13(3) requires the assessments to be complete before the permit issues; without it, the streamlined benefits do not yet apply.

2. Scope your project against the baseline permit. Run a gap analysis between your project's specifications and the baseline permit's parameters. Activities outside it trigger additional, installation-specific permits under Article 13(4); identify these early so documentation can be prepared in parallel.

3. Prepare for the 12-month clock. The 12-month limit under Article 13(5) runs from a comprehensive application. Ensure your submission is genuinely comprehensive to avoid delay.

4. Watch for strategic-project opportunities. Assess whether the project could meet at least two of the Article 14 criteria, potentially unlocking additional regulatory and financial advantages.

5. Use single information points. Engage the single information points under Article 12, which can help assess strategic-project qualification and coordinate the residual permitting steps.

Common misconceptions

Misconception 1: No environmental assessments are needed for data centres in acceleration zones. Incorrect. Assessments remain mandatory but are shifted to the zone level. Article 13(3) requires the Member State to carry them out before the baseline permit issues; operators are exempt only from repeating the generic zone-level assessments.

Misconception 2: The aggregated baseline permit covers everything in the zone. No. Article 13(4) requires additional permits for activities falling outside the baseline permit. New environmental risks or scales not contemplated at zone level still require installation-specific permitting.

Misconception 3: All EU data centre projects benefit from this zone-level model. No. It applies only to data centres deployed in formally designated acceleration zones. Projects outside remain subject to standard national permitting.

Misconception 4: The 12-month timeline includes the zone-level assessment. No. The Article 13(5) limit applies to the project's administrative applications after the baseline permit is in place; the zone-level assessments under Article 13(3) occur earlier, during zone designation and baseline-permit issuance.
