A US House Democrat asks Elon Musk to respond to concerns about pollution tied to xAI’s data centres, according to multiple reports. The request comes as lawmakers scrutinize the environmental impacts of rapidly expanding artificial intelligence infrastructure. The representative’s letter calls on Musk to address what steps, if any, xAI is taking to prevent or mitigate environmental harm, and to provide information related to the alleged pollution. The reports indicate the inquiry focuses on data-centre operations and their surrounding effects, including potential emissions, waste or other environmental impacts associated with the facilities. The sources describe the request as part of broader congressional attention to environmental compliance and accountability from major technology and AI players. The articles do not indicate a resolution to the allegation, nor do they provide definitive findings on wrongdoing. The next steps depend on the company’s response to the lawmakers’ questions and any related review or enforcement actions that may follow.
