Summary Under the proposed Cloud and AI Development Act (CADA), Member States cannot designate "data centre acceleration zones" without first assessing the site's ability to function sustainably. Article 10(1)(h) explicitly requires evaluating the site's capacity to prevent or minimise environmental impacts, support the reduction of carbon emissions, and ensure climate resilience. These qualitative designation criteria are legally binding prerequisites that feed into Article 11, which mandates that data centres operating within these zones must meet specific key performance indicators (KPIs) defined in Delegated Regulation (EU) 2024/1364. As proposed, this dual-layer approach ensures that the acceleration of infrastructure does not come at the expense of the EU's green transition or long-term operational stability.

Detail

The proposed Cloud and AI Development Act (CADA), COM(2026) 502 final, seeks to address the critical shortage of computing capacity in the European Union by accelerating the deployment of data centres. A central mechanism for this is the creation of "data centre acceleration zones" (acceleration zones). While the primary legislative intent is to streamline permitting and boost capacity, the proposal embeds sustainability as a non-negotiable gatekeeper for designation. The legislation recognises that rapid deployment must not trigger a "race to the bottom" regarding environmental standards or expose critical infrastructure to climate-related risks.

The Mandate of Article 10(1)(h)

The core sustainability obligation for the designation phase is found in Article 10(1) of the proposal. This article lists the specific aspects Member States must consider when designating at least one acceleration zone within their territory. Point (h) is dedicated exclusively to environmental sustainability and climate adaptation.

The text of Article 10(1)(h) requires Member States to assess:

"the ability of the site or area to function sustainably, particularly as regards preventing or minimising environmental impacts and supporting the reduction of carbon emissions and its climate resilience."

This provision establishes a three-pronged test for any potential acceleration zone:

  1. Minimising Environmental Impacts: The site must demonstrate a capacity to avoid or mitigate negative effects on the local ecosystem, biodiversity, and natural resources.
  2. Supporting Carbon Reduction: The location and its associated infrastructure must facilitate the reduction of carbon emissions, implying a need for access to low-carbon energy sources and efficient grid integration.
  3. Climate Resilience: The site must be robust against future climate shocks, such as extreme heat, flooding, or water scarcity, which could disrupt the continuous operation of data centres.

By codifying these factors into the designation criteria, the proposal ensures that sustainability is not a post-designation add-on but a foundational element of the zone's identity. Sites with high climate vulnerability or poor environmental prospects would, as proposed, be ineligible for the accelerated permitting regime.

The Operational Link: Article 11 and Delegated Regulation (EU) 2024/1364

The qualitative assessment required by Article 10(1)(h) is directly linked to the quantitative operational requirements set out in Article 11. While Article 10 focuses on the site's potential to function sustainably, Article 11 dictates the performance standards for data centres once they are deployed within those zones.

Article 11(1) states:

"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)."

This creates a cohesive regulatory framework:

  • Designation (Article 10): The site is selected based on its inherent ability to minimise environmental impact, reduce carbon, and withstand climate risks.
  • Operation (Article 11): The data centres built on that site are legally bound to meet strict, measurable efficiency standards defined in the Delegated Regulation.

It is important to note that the specific KPIs (such as Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE)) are enumerated in Delegated Regulation (EU) 2024/1364, not in the CADA text itself. CADA acts as the trigger, mandating the use of these existing EU standards for all projects within acceleration zones. This ensures that the "acceleration" of deployment is matched by the "acceleration" of sustainability performance.

Climate Resilience and Energy Analysis

The reference to "climate resilience" in Article 10(1)(h) is particularly critical for the long-term viability of the EU's digital infrastructure. Data centres are energy-intensive and require stable cooling and power conditions. A site prone to flooding or extreme heat poses a direct risk to service continuity, which contradicts the broader CADA objective of ensuring operational autonomy and public order.

This resilience requirement is reinforced by Article 10(2)(a), which obliges Member States to conduct a comprehensive analysis of the energy needs and greenhouse gas emission impacts of current and future acceleration zones. This analysis must be reviewed at least every three years and must inform national grid planning. By linking the designation criteria to a forward-looking energy analysis, the proposal ensures that the expansion of data centre capacity is supported by sustainable energy infrastructure and does not exacerbate carbon emissions.

Integration with Spatial Planning and Environmental Assessments

Sustainability considerations under CADA extend beyond the specific zone to the broader spatial planning context. Article 10(3) requires national, regional, and local authorities to include provisions for data centre development in their spatial and development plans. Crucially, where these plans are subject to environmental assessments under Directive 2001/42/EC (Strategic Environmental Assessment) or Directive 92/43/EEC (Habitats Directive), those assessments must be combined.

This integration ensures a holistic evaluation of the environmental footprint, including impacts on water bodies (Directive 2000/60/EC) and protected habitats. Furthermore, Article 11(2) supports these sustainability goals by prohibiting "speculative reservation or foreclosure practices." This prevents the hoarding of land or energy capacity in acceleration zones by entities that do not intend to build sustainable infrastructure, ensuring that resources are reserved for projects that genuinely contribute to the EU's digital and green objectives.

What this means for you

For public-sector planners, regional authorities, and environmental officers involved in the designation or management of data centre acceleration zones, the sustainability provisions of the proposed CADA have several practical implications:

  1. Formal Sustainability Assessment: You must conduct a formal, documented assessment of any potential acceleration zone against the criteria in Article 10(1)(h). This goes beyond standard zoning compliance. You must explicitly demonstrate how the site prevents environmental impacts, supports carbon reduction, and ensures climate resilience. This documentation will be a prerequisite for the zone's legal designation.
  2. Energy and Grid Analysis: You are required to collaborate with transmission and distribution system operators to produce a comprehensive energy analysis for the zone. This analysis must assess greenhouse gas emission impacts and inform national grid planning, ensuring that the proposed data centre capacity can be powered sustainably without overloading the grid.
  3. Enforcement of Delegated KPIs: Once a zone is designated, you must ensure that all data centre operators comply with the KPIs from Delegated Regulation (EU) 2024/1364. Your permitting and monitoring processes must include mechanisms to track metrics like PUE and WUE. Non-compliance with these standards could jeopardise the project's status within the acceleration zone.
  4. Climate Risk Integration: Incorporate climate resilience into your risk assessments for all data centre projects. This includes evaluating risks related to extreme weather, water scarcity for cooling, and grid stability. Projects in areas with high climate risk may require specific mitigation measures or may be deemed unsuitable for designation.
  5. Combined Environmental Assessments: When preparing spatial plans for acceleration zones, ensure that environmental assessments are combined where applicable. This streamlines the process but requires a comprehensive approach to evaluating impacts on water, habitats, and biodiversity, as mandated by Article 10(3).

Common misconceptions

Misconception 1: Sustainability is only about operational efficiency (PUE/WUE). While Article 11 focuses on operational KPIs like PUE and WUE, Article 10(1)(h) expands the scope to include the site's inherent ability to function sustainably. This includes climate resilience, carbon reduction potential, and minimising broader environmental impacts on local ecosystems. Sustainability is a site-selection criterion, not just an operational metric.

Misconception 2: Acceleration zones prioritise speed over environmental protection. The proposal explicitly states that acceleration zones must ensure compliance with applicable Union law, including requirements relating to energy efficiency and environmental protection [Recital 38]. The designation process requires a balanced approach where speed is achieved through streamlined permitting, not by bypassing environmental safeguards. In fact, the requirement for climate resilience ensures that speed does not come at the cost of long-term viability.

Misconception 3: Member States can define their own sustainability metrics. No. Article 11(1) mandates the use of the key performance indicators specified in Delegated Regulation (EU) 2024/1364. Member States cannot create their own alternative metrics for sustainability within acceleration zones. This harmonisation ensures a consistent level of environmental protection across the EU and prevents regulatory arbitrage.

Misconception 4: Sustainability considerations apply only to new data centres. The requirements apply to data centres deployed in acceleration zones, which includes new builds and expansions. However, the designation of the zone itself is a forward-looking exercise that considers the future energy needs and environmental impacts of the capacity to be deployed there [Article 10(2)(a)].
