A new study warns that Europe's proposed cloud sovereignty legislation could saddle the continent with €115 billion in costs over the next ten years. The research, commissioned by CCIA Europe and conducted by the European Centre for International Political Economy, targets the European Commission's Cloud and AI Development Act, which aims to reduce reliance on American cloud providers. CCIA Europe's membership includes Amazon, Google, and Meta, firms with substantial interests in maintaining European demand for U.S. cloud services.
The study puts the price tag at more than six times the Commission's upper projection of €18 billion. Direct public-sector expenses are estimated at €33.3 billion, while private companies in banking, healthcare, energy, and transport could face an additional €80 billion. That larger figure, however, rests on a modeled assumption: it presumes Brussels will extend sovereignty mandates beyond government procurement to cover a quarter of cloud workloads in critical private industries. The research identifies code rewriting and system re-architecting as the largest expense drivers, accounting for 69 percent of projected costs. On a per-worker basis, Luxembourg would shoulder the steepest burden at €1,711 over the decade, followed by Denmark at €905, Austria at €900, Finland at €864, and Ireland at €856.
According to CCIA Europe policy manager Mitchell Rutledge, "Member States cannot rely on the Commission's incomplete estimates when deciding CADA's strict sovereignty requirements for cloud and AI providers." The study argues that forcing businesses away from existing cloud infrastructure would trigger expensive software redevelopment, with taxpayers and enterprises ultimately bearing the expense. The report takes particular aim at Article 31 of the proposed law, which it contends could empower the Commission to impose sovereignty requirements on essential private-sector services.
The research's credibility is complicated by the interests of its sponsors. CCIA represents several U.S. technology giants that dominate Europe's cloud market, including Amazon and Google, both of which have spent years selling cloud services to European customers. More recently, both firms have developed sovereign cloud products designed to address worries about foreign ownership and data access. Amazon has been building its AWS European Sovereign Cloud, while Google markets a portfolio of sovereign cloud solutions. Meta, another CCIA member, maintains interests in European AI infrastructure, though it doesn't operate a commercial cloud service on the scale of AWS or Google Cloud. The arrangement allows these companies to sell customers sovereignty-branded offerings while simultaneously funding warnings against government-imposed sovereignty mandates.
CCIA is pressing EU governments to revise the proposed legislation, confine sovereignty restrictions to sensitive workloads, and replace requirements tied to corporate origin or staff nationality with risk-based technical protections. Whether Europe's sovereignty ambitions will prove as costly as the study forecasts remains uncertain. What's clearer is that the firms issuing these warnings stand to benefit financially if Europe continues purchasing American cloud technology. The collision between regulatory ambition and commercial interest suggests that cloud sovereignty will remain a flashpoint as Brussels weighs independence against infrastructure costs.
