US tech companies including Google, Amazon, and Meta successfully lobbied EU officials to insert confidentiality clauses into environmental regulations, keeping their European datacenters' emissions data from public disclosure. The Guardian confirmed Microsoft and industry trade groups had their confidentiality demands adopted nearly verbatim into law. This matters because it blocks public scrutiny of energy use and emissions from infrastructure that powers digital services across Europe — data essential for evaluating tech's climate impact. Legal experts cited in the reporting warn these secrecy provisions may violate EU transparency requirements, but enforcement remains uncertain.
