Summary The proposed Cloud and AI Development Act (CADA) does not directly cap carbon emissions in data centre acceleration zones. Instead, it would have Member States weigh sustainability when designating zones. Under Article 10(1)(h), one of the aspects a Member State "shall consider" is the site's ability to function sustainably, particularly as regards preventing or minimising environmental impacts and supporting the reduction of carbon emissions and its climate resilience. Other aspects — clean energy generation and storage, and a greenhouse-gas-impact analysis — reinforce this. The aim is to embed sustainability into the designation and conditions, rather than treat it as an afterthought.

Detail

CADA proposes to expand the EU's data centre capacity while addressing the environmental impact of these energy-intensive facilities. To balance these, it introduces "data centre acceleration zones" (Article 10), where deployment is facilitated through streamlined permitting and planning — but with sustainability woven into how zones are designated and run. CADA is a proposal and not yet in force; the points below describe what the text would require.

The main route by which acceleration zones bear on carbon emissions is the designation aspects in Article 10(1). When designating a zone, a Member State "shall consider" several aspects. Most directly relevant is Article 10(1)(h): "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 puts long-term environmental viability among the considerations before a site gains acceleration status — though, as one of the aspects to "consider," it guides the assessment rather than setting a fixed emissions threshold.

Article 10(1)(b) adds "the available and future power grid capacity and the possibility and conditions for on-site storage and clean energy generation." By bringing clean energy generation and storage into the designation calculus, the proposal encourages integrating renewables and managing energy locally, reducing reliance on fossil-heavy grid electricity and helping ensure that AI-driven compute demand is met more sustainably.

The sustainability dimension continues into the conditions within zones. Article 11(1) provides that, 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" (adopted under the Energy Efficiency Directive, Directive (EU) 2023/1791), referring to Annex II points (a) to (n). These KPIs provide a standardised, measurable basis for assessing energy efficiency and environmental impact, turning "reducing carbon emissions" into something quantifiable rather than aspirational.

Finally, Article 10(2)(a) — which applies "where appropriate to facilitate the development of acceleration zones" — would have Member States conduct, and review at least every three years, a comprehensive analysis of the energy needs and their respective greenhouse-gas impacts for current and future zones. This recurring analysis keeps the environmental picture current and lets authorities respond to emerging risks.

What this means for you

For public-sector and procurement officers, these provisions change how you evaluate data centre providers. Sustainability moves from a secondary criterion toward a built-in expectation.

First, where a provider operates in an acceleration zone, you can look for evidence of how the zone's sustainability aspects (Article 10(1)(h) and the clean-energy element of Article 10(1)(b)) and the KPI-based requirements under Article 11(1) translate into the provider's actual performance. This can help differentiate providers, favouring those with verifiable emissions reductions and climate-resilience plans.

Second, you can use the streamlined route of acceleration zones to accelerate deployment of sustainable infrastructure — while remaining vigilant. The proposal does not automatically certify every data centre in a zone as low-carbon; oversight matters. Consider contractual clauses requiring providers to report against the mandated KPIs and to demonstrate ongoing efforts to minimise impacts.

Third, prioritising sustainable solutions aligns procurement with EU climate objectives, reduces the public sector's footprint, and helps future-proof against potentially stricter requirements down the line.

Common misconceptions

A common misconception is that designation as an acceleration zone automatically confers a "green label" on every data centre within it. In reality, CADA has Member States consider sustainability aspects at designation (Article 10(1)(h)); it does not certify individual data centres as sustainable. Measurable requirements come through the KPIs under Article 11(1). Buyers should still conduct due diligence on specific providers.

Another misconception is that zones focus only on speed, ignoring the environment. While the goal is to accelerate rollout, CADA ties that acceleration to sustainability — through the greenhouse-gas-impact analysis (Article 10(2)(a), where appropriate) and the clean-energy consideration (Article 10(1)(b)) — seeking rapid deployment achieved through sustainable practices, not despite them.

A third is that emissions reductions rest solely with operators. Operators are central, but CADA also places duties on Member States and authorities — designating zones against sustainability aspects, applying KPIs, and (where appropriate) reviewing energy impacts — creating a shared-responsibility model that public bodies help enforce through procurement and oversight.
