A group of residents files a class-action lawsuit against Microsoft over alleged environmental impacts from the company’s new $7.3 billion AI data center in Mount Pleasant, Wisconsin. Multiple outlets report that neighbors claim the facility produces nonstop, excessive noise, describing it as “freight train-like,” generated by equipment such as generators and HVAC systems. Residents also allege related harms to their properties.
Microsoft, according to the reports, responds by saying it is committed to being a “good neighbor” and that it has taken steps to reduce noise. Some reporting adds that the company argues the problem has already been resolved, while residents maintain the issues continue.
One outlet also reports allegations beyond noise, including extreme light pollution and dust, tied to the data center’s operations. The lawsuit is framed by plaintiffs as part of broader community concerns about the expansion of AI infrastructure in the area, with additional data centers expected. The outcome of the litigation has not been reported, and the claims have yet to be tested in court.
