A federal judge has ruled that a lawsuit accusing SpaceX-owned xAI of Clean Air Act violations at its Memphis data center can continue, rejecting claims that the turbines involved are exempt from air permitting.

A federal court has allowed a lawsuit brought by the NAACP against xAI, the artificial intelligence company owned by SpaceX, to move forward. The suit accuses xAI of operating gas turbines at its Colossus data center near Memphis without the necessary air pollution permits, constituting a violation of the Clean Air Act. The Southern Environmental Law Center, representing the NAACP, alleges that xAI installed and ran at least 35 combustion turbines and other polluting equipment without obtaining the required preconstruction or operating permits.

xAI sought dismissal of the claims, arguing that its turbines are mobile sources exempt from permitting rules and that the plaintiffs lacked standing. However, Judge Debra M. Brown ruled against these defenses in a detailed decision issued on October 31, 2026. She found that the plaintiffs have statutory standing under federal environmental law and that the turbines do not qualify as mobile sources under Mississippi’s state implementation plan. Additionally, she rejected the assertion that citizen suits like this infringe on the executive powers of the federal government, noting that such lawsuits are brought by citizens on their own behalf to address harms affecting them.

This ruling follows a similar denial of a motion to dismiss filed by the Department of Justice earlier in the month, reinforcing the legal viability of the NAACP’s case. Abre’ Connor, director of environmental and climate justice at the NAACP, called this decision "another important victory in our effort to hold xAI accountable," emphasizing their position that the company cannot lawfully operate gas turbines without proper permits.

The lawsuit unfolds amid growing public and governmental scrutiny of data centers due to environmental concerns. New York recently enacted a moratorium on new data centers, and several other states and municipalities are considering similar restrictions. These developments have pressured major tech companies such as Amazon and Microsoft to increase transparency in their regulatory dealings and reflect the growing environmental activism surrounding AI and data infrastructure.

As the NAACP lawsuit progresses, it may set significant precedents for how AI data centers are regulated and held accountable for environmental impacts, particularly concerning air pollution and community health.
