EU Proposes Mandatory Sustainability Rating for AI Data Centres
The European Commission has proposed a mandatory sustainability rating for data centres, creating a common EU yardstick for their energy and water use. Based on Article 33 of the EU Energy Efficiency Directive, the rating would cover facilities with installed IT power demand of at least 500 kilowatts, with voluntary participation for smaller sites. Metrics would include Power Usage Effectiveness (PUE), Water Usage Effectiveness (WUE), and the share of renewable energy, with stricter rules on guarantees of origin, PPAs, and on-site generation. Labels would be generated automatically from reported data, updated annually, and first published in 2027, subject to approval by member states and the European Parliament. The rating is expected to feed into sustainable finance, public procurement, and the planned Cloud and AI Development Act. The article also cites IEA forecasts of surging data-centre electricity demand and research by Silicon Austria Labs on energy-efficient AI hardware.
The proposed EU rating introduces mandatory, comparable sustainability metrics for data centres, potentially affecting energy costs, site selection, financing, and procurement for the cloud/AI infrastructure that supports advertising and marketing technology.

US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
