The NAACP and its Mississippi State Conference are suing Elon Musk's xAI, alleging that it did not obtain a permit before emitting large amounts of pollution into a Memphis-area community. The suit alleges that xAI and subsidiary MZX Tech violated the Clean Air Act by not obtaining a permit for their Colossus Gas Plant, which powers its Colossus 2 data center with 27 gas turbines. The lawsuit also alleges that the plant emits large quantities of pollution linked to asthma, respiratory diseases, heart problems, and certain cancers. The NAACP has accused xAI of evading clear air laws to operate dirty turbines that emit pollution and known carcinogens.
