Key Takeaways
- Microsoft, DigitalEurope (which includes Microsoft, Google, Amazon, Meta) and Video Games Europe successfully lobbied the EU to keep individual datacentre performance data confidential.
- The confidentiality provision was inserted almost verbatim into the EU’s energy‑efficiency directive after industry lobbying in 2024.
- As a result, researchers and the public can only access national‑level summaries, obscuring the true environmental impact of each facility.
- The boom in AI‑driven datacentres is increasing power demand, often met by fossil‑gas generation, worsening greenhouse‑gas emissions.
- Legal scholars argue the blanket secrecy clause breaches EU transparency rules and the Aarhus Convention on public access to environmental information.
- Internal Commission communications show officials reminding national authorities to withhold all individual datacentre KPIs from freedom‑of‑information requests.
- While the EU plans a future sustainability‑score database to compare facilities, the current rule would keep most operator‑reported data hidden.
- Experts contend that any confidentiality should be assessed case‑by‑case rather than applying a sweeping presumption that favours corporate interests over public scrutiny.
Investigation Reveals Tech Lobbying to Hide Datacentre Emissions
An investigative collaboration between Investigate Europe, the Guardian and other media partners uncovered that major U.S. technology firms—including Microsoft—pressed the European Union to conceal the environmental footprint of individual datacentres. Documents obtained through freedom‑of‑information requests show that industry submissions during a 2024 public consultation demanded that all key performance indicators (KPIs) for each facility be classified as confidential. The requests were framed as necessary to protect commercial interests, yet the resulting EU rule mirrors the industry’s wording almost exactly, indicating a direct influence of corporate lobbying on legislative text. This secrecy provision now shields detailed data on energy consumption, carbon emissions and water use from public view, leaving analysts with only aggregated, nation‑level statistics that mask the true scale of the sector’s ecological impact.
EU Rule Inserted Verbatim After Industry Lobbying
The confidentiality clause appeared in the Commission’s updated Energy Efficiency Directive almost word‑for‑word after the tech sector’s lobbying effort. The final regulation states: “the commission and member states concerned shall keep confidential all information and key performance indicators for individual datacentres that are communicated to the database … Such information shall be considered confidential information affecting the commercial interests of operators and owners of datacentres.” Only a couple of words differ from the original industry proposal, underscoring how closely the legislators followed the corporations’ wording. Legal experts note that such a near‑identical transposition is atypical in EU policy‑making and raises serious questions about the integrity of the legislative process when private interests can dictate the precise language of public‑interest rules.
Impact on Researchers and Transparency
Because the rule treats every individual datacentre’s KPI as confidential, scholars, NGOs and journalists are barred from obtaining facility‑specific data through standard freedom‑of‑information channels. Researchers must rely on national‑level aggregates, which dilute variations between efficient and inefficient sites and impede efforts to benchmark performance or identify polluters. Alex de Vries‑Gao of Vrije Universiteit Amsterdam lamented that “public information is extremely limited. You typically have to bend backward to come up with any numbers,” highlighting how the secrecy hampers independent analysis of AI‑related energy use. The lack of granular data also weakens the ability of policymakers to target interventions where they would be most effective, such as incentivising renewable‑energy procurement or imposing efficiency upgrades on the worst‑performing facilities.
Rise of AI Datacentres and Fossil‑Fuel Dependency
The surge in generative AI services has driven a rapid expansion of chip‑filled warehouses across Europe, each demanding massive electricity supplies for training and inference workloads. To meet this spike, many operators are turning to readily available fossil‑gas plants, especially in regions where renewable‑energy infrastructure lags behind demand. Consequently, the environmental toll of AI growth is not merely a matter of increased electricity consumption but also a potential rise in carbon dioxide and methane emissions from gas‑fired generation. The EU’s ambition to triple its datacentre capacity within five to seven years—intended to secure a leadership position in AI—could exacerbate these trends if the sector’s energy mix remains heavily weighted toward fossil fuels without transparent accountability.
Legal Analysis: Possible Violation of Aarhus and EU Transparency Rules
Several environmental law experts have warned that the blanket confidentiality clause likely conflicts with the EU’s own transparency obligations and the Aarhus Convention, which guarantees public access to environmental information. Prof. Jerzy Jendrośka, a longtime member of the Aarhus oversight body, stated that in two decades he cannot recall a comparable case where industry lobbying produced such a direct infringement. Luc Lavrysen, former president of Belgium’s constitutional court, called the clause “clearly in violation” of EU transparency rules, while Kristina Irion of the University of Amsterdam argued that a “sweeping presumption of confidentiality” incorrectly privileges corporate interests over the public’s right to at least some of the data. They collectively recommend that any confidentiality determination be made on a case‑by‑case basis, weighing legitimate business secrets against the societal need for environmental oversight.
Examples of the Secrecy Clause in Action
Internal Commission emails obtained by the investigative team show officials reminding national authorities of their duty to “keep confidential all information and key performance indicators for individual datacentres.” One official noted that the Commission had already received numerous requests for documents from media and the public, all of which had been refused citing the secrecy provision. This illustrates how the rule is being operationalised to deny access even when there is a clear public‑interest motive, such as investigating whether a particular facility is exceeding emission limits or relying disproportionately on fossil‑gas power. The ability to withhold such data undermines governmental oversight and prevents civil society from holding datacentre operators accountable for their environmental commitments.
EU’s Transparency Goals and Future Rating Scheme
Despite the current secrecy, the EU envisions a two‑step approach to improve datacentre sustainability. The 2023 update to the Energy Efficiency Directive already obliges operators to report KPIs; the Commission’s guidance proposed publishing “aggregated” environmental metrics as a first step. A second phase, currently under public consultation, aims to develop a common EU rating scheme that would publish sustainability scores derived from the reported data, enabling regional comparisons and encouraging efficiency improvements. However, under the prevailing rule, the majority of what operators submit would remain classified as confidential, severely limiting the usefulness of any public scorecard. Critics argue that without access to the underlying data, any rating system would lack credibility and could become a superficial marketing tool rather than a genuine driver of greener practices.
Industry Statements and Internal Commission Position
Microsoft responded to the inquiry by asserting its support for greater transparency, claiming that sustainability disclosures can improve outcomes and public trust, while simultaneously emphasizing the need to protect confidential business information. A spokesperson said the firm is “taking further steps to increase openness, while protecting confidential business information.” Meanwhile, sources close to the Commission indicated that the internal stance fears that making each datacentre’s information public could discourage operators from reporting their sustainability metrics altogether. This apprehension appears to contradict existing EU data showing that only 36 % of eligible datacentres have complied with current reporting requirements, suggesting that secrecy may already be reducing participation rather than encouraging it.
Experts’ Call for Case‑by‑Case Confidentiality Assessment
Academics and practitioners urge the EU to replace the sweeping confidentiality presumption with a nuanced, case‑by‑case evaluation. They argue that legitimate trade secrets—such as specific chip designs or proprietary cooling technologies—can be protected without concearding basic environmental performance indicators like power usage effectiveness (PUE) or carbon intensity. By allowing public access to at least a subset of KPIs, regulators could maintain effective oversight while still safeguarding genuinely sensitive commercial information. Such an approach would align the EU’s datacentre policy with its broader climate objectives, the Aarhus Convention, and the principle that environmental transparency is a cornerstone of sustainable development.
In sum, the investigation reveals how a handful of powerful tech firms succeeded in shaping EU legislation to shield detailed datacentre environmental data from public scrutiny. The resulting secrecy hampers research, weakens regulatory oversight, and potentially conflicts with EUlegal commitments to transparency and public access to environmental information. Moving forward, the EU must reassess the balance between protecting legitimate business interests and ensuring that the ecological impact of the rapidly expanding AI‑driven datacentre sector is visible, measurable, and subject to accountable governance.
