Microsoft and Digital Europe successfully lobbied the European Commission to insert a secrecy clause into EU law that hides environmental data of data centers, violating the international OHUS Convention. However, multiple EU institutions, legal experts, and environmental groups are challenging this clause, demonstrating Europe's institutional resilience against corporate lobbying.
An investigation by Investigate Europe uncovered that Microsoft and the tech lobby giant Digital Europe successfully lobbied the European Commission to insert a confidentiality clause into EU law. This clause blocks public access to critical information regarding the environmental impact of data centers, including energy use and water consumption. This secrecy shields vital data from affected communities, researchers, and journalists, undermining the transparency that Europe is supposed to guarantee.
Europe is poised to triple its data center capacity over the next five years, with an expected investment of 176 billion euros. These data centers have a substantial environmental footprint, consuming massive amounts of energy, using large quantities of water for cooling, and potentially emitting significant CO2 if power sources are not decarbonized.
In 2023, the EU passed the Energy Efficiency Directive, requiring data center operators to report key performance indicators such as energy use and water consumption. The European Commission began collecting this data in 2024. Initially, the draft regulations stated that this data should be published in aggregated form, allowing the public to see environmental impacts by operator.
At the start of 2024, Microsoft and Digital Europe submitted identical feedback during the standard consultative process, proposing a new article that classified all individual information on data centers as confidential, citing commercial interests. The Commission incorporated this industry-drafted language almost verbatim into the final 2024 implementing regulation.
As a result, information on the environmental footprint of individual data centers is now kept secret. An email from early 2025 reveals a senior Commission official instructing national authorities to keep confidential all information and key performance indicators for individual data centers.
This means American tech companies successfully lobbied to hide environmental damage from European citizens, a clear case of corporate capture.
However, Europe’s institutional architecture has safeguards designed to catch such issues. Ten leading legal scholars have stated that the blanket confidentiality clause likely violates the Aarhus Convention (OHUS Convention), an international treaty guaranteeing public access to environmental information.
The Aarhus Convention guarantees three key rights:
The EU and all 27 member states have ratified this treaty, making them legally bound by its requirements.
Client Earth, an environmental legal group, has filed a court challenge arguing that the Commission’s restrictions breach the EU’s obligations under the Aarhus Convention. The EU Ombudsman has opened an investigation, and the European Parliament’s Civil Liberties Committee has adopted a report calling for faster responses to document access requests, clearer classification rules, and earlier access to policy documents.
This multi-pronged institutional response exemplifies what institutional resilience looks like. While one part of the EU was captured by corporate lobbying, multiple independent safeguards immediately activated to counteract it.
This situation contrasts with how corporate lobbying often works in the United States, where regulatory capture frequently faces little institutional pushback. In the US, if a company successfully lobbies to hide environmental data, there are rarely independent investigations, court challenges, or parliamentary committees demanding transparency reforms happening simultaneously.
Europe’s system includes:
All these mechanisms were triggered simultaneously by Microsoft and Digital Europe’s lobbying effort.
The secrecy clause is not the only business-friendly carveout industry pushed into EU regulations. The Commission also proposed a draft bill to speed up environmental impact assessments for data center construction projects, setting hard response deadlines and capping community consultation at 90 days.
Documents obtained through Freedom of Information Requests show Microsoft met with EU officials in late October to discuss permitting, calling for capping deadlines and describing streamlining permitting procedures as a critical enabler.
Client Earth lawyer Yannis Agapakis warned that contracting community consultation could cause people to miss their chance to identify serious issues, potentially legitimizing projects with procedural or substantive illegalities. This warning is part of the public record and will be used by activists and courts to challenge implementation.
The court case filed by Client Earth will test whether the Commission can classify environmental information as commercially confidential in violation of the Aarhus Convention. If the court strikes down the secrecy clause, it will set a precedent that corporate lobbying cannot override treaty obligations on environmental transparency.
The Ombudsman’s investigation, while unable to overturn regulations, creates political pressure and establishes that the Commission overreached. Combined with the Parliament demanding transparency reforms, multiple institutional pressures are converging.
This process is likely to continue through 2026, but the trajectory favors transparency. Microsoft and Digital Europe may have succeeded in lobbying the Commission, but they underestimated Europe’s institutional antibodies.
Democratic systems are not perfect. Officials can be captured by industry, and corporate lobbying sometimes succeeds. However, resilient democracies are designed with overlapping safeguards so that when one institution fails, others can correct it.
Europe’s independent courts, Ombudsman, activist groups with legal standing, parliamentary oversight, and binding international treaties are all designed to catch and correct attempts like Microsoft’s to hide environmental data.
The secrecy clause may have made it into law, but the fight to strike it down is just beginning, and the institutional architecture favors transparency and public access to environmental information.
This case highlights the importance of vigilance, legal frameworks, and institutional checks in protecting public interest against corporate influence.
