The NAACP has initiated legal action against xAI and its subsidiary MZX Tech, accusing them of running unpermitted methane gas turbines to supply power to their Colossus 2 data center located in South Memphis. The civil rights organization is petitioning the federal district court in the Northern District of Mississippi to rule that the company has contravened the Clean Air Act. They are seeking an injunction to cease the use of the unauthorized turbines and the imposition of financial penalties on xAI for its alleged breaches of federal law.
The lawsuit contends that xAI, the artificial intelligence startup founded by Elon Musk and now under the ownership of SpaceX, is operating 27 gas turbines without the necessary air permit. These turbines are reportedly fueling Colossus 2, one of an expanding network of data centers established by xAI to train its AI assistant, Grok. Gas turbines are known to emit pollutants, hazardous chemicals, and fine particulate matter, which have been linked to serious health issues including heart conditions, respiratory illnesses, and certain types of cancer. These concerns are amplified by the close proximity of Colossus 2 to residential areas.
Operating these turbines without an air permit constitutes a violation of the Clean Air Act, which mandates that all sources of pollution must obtain permits prior to operation or construction. The NAACP is being represented in this legal battle by the Southern Environmental Law Center and Earthjustice. Prior to filing the lawsuit, the NAACP formally notified xAI of its intent to sue within 60 days, a procedural step required by the Clean Air Act. The company’s lack of response to this notice has prompted the lawsuit’s progression.
“xAI’s continued operation of these turbines without a permit and without adequate pollution controls is not only illegal, it’s an insult to families living nearby who for months have expressed serious concerns about how air pollution from the company’s personal power plant could impact their health and well-being,” stated Ben Grillot, a Senior Attorney for the Southern Environmental Law Center. “xAI must be held accountable for its reckless, unlawful actions — and that’s exactly what this lawsuit aims to do.”
In addition to the substantial expenses associated with acquiring the components necessary for training and operating AI models, AI companies are frequently required to generate their own power for the data centers housing this infrastructure. Reports suggest that Oracle is also exploring the use of gas generators, similar to xAI. In contrast, Google, Meta, and Amazon have made significant investments in or established agreements with nuclear energy providers to power their data center operations.
The development of new energy sources for data centers is one of several strategies proposed by the Ratepayer Protection Pledge, an agreement signed by numerous tech companies aimed at preventing data centers from escalating average consumer energy costs. While the rapid expansion of new energy infrastructure may help mitigate costs, it does not address the negative environmental consequences of having a new power plant situated within a community. This aspect appears to be of less concern to the Trump administration.
In his most recent AI framework proposal, President Donald Trump largely overlooked the environmental ramifications of AI, instead advocating for the streamlining of permitting processes for elements such as on-site energy generators.
