The NAACP and an environmental group said Tuesday that they intend to sue Elon Musk’s artificial intelligence company xAI over concerns about air pollution generated by a supercomputer facility located near predominantly Black communities in Memphis.

The Southern Environmental Law Center on behalf of the NAACP filed a 60-day intent to sue notice against xAI for alleged Clean Air Act violations.

The civil rights group said air pollution related to at least 35 combustion turbines at the facility — operating without proper permits — negatively impacts nearby Black communities.
