The NAACP and two major environmental law organizations filed a lawsuit against Elon Musk's xAI Corp. and its subsidiary MZX Tech LLC, alleging the company installed gas-powered turbines in Mississippi to power its Colossus II data center in Tennessee without obtaining required air permits, putting predominantly Black communities at risk. The case represents a growing clash between the rapid expansion of artificial intelligence infrastructure and the health and environmental concerns of vulnerable neighborhoods.

What Is the xAI Data Center Dispute About?

xAI built Colossus II, a massive data center that supports the Grok AI chatbot, straddling the Tennessee-Mississippi border with over one gigawatt of computing power. The gas turbines that power the facility sit about 1.6 miles across the state line in Southaven, Mississippi, where approximately 39 percent of the population is Black according to the 2024 US Census Bureau.

The NAACP claims that xAI and MZX Tech initially began operating 27 gas turbines without an air permit or regard for public health. According to the lawsuit, the Colossus gas plant emits significant amounts of harmful pollutants, including nitrogen oxides and formaldehyde, which are tied to increases in asthma, respiratory diseases, heart problems, and certain cancers. The environmental groups are seeking approximately $124,400 in penalties per day for violations and have moved for a preliminary injunction.

A February 2026 report commissioned by the Southern Environmental Law Center determined that health risks for communities in Tennessee and Mississippi would increase from exposure to the proposed permanent gas turbines for Colossus II.

How Does This Connect to Environmental Justice and Civil Rights?

Abre' Conner, the NAACP's director of environmental and climate justice, grew up in Polk County, Florida, surrounded by phosphate plants that she believes contributed to her debilitating asthma attacks. Her personal experience with environmental inequity shaped her career in environmental law and her current work fighting polluting industries in communities of color.

"What we're seeing with these AI data centers is for many of them, they're trying to get it up and running, no matter the cost, as quickly as possible," said Conner.

NAACP President and CEO Derrick Johnson described environmental justice as "important as any other civil rights issue," framing the lawsuit as an effort to "shed light" on the impact data centers are having on communities across the nation.

"We're in the midst of this technological revolution, which is taking place at an unprecedented scale and scope and speed without a clear plan, vision, strategy for protection for American consumers. And most particularly Black and Brown people," said Cornell William Brooks, a former NAACP president and current social justice professor at the Harvard Kennedy School.

Brooks compared data centers to other industries that externalize the cost of doing business by dumping pollution into rivers and undermining benefits for nearby communities. The pattern, he argued, reflects a broader failure to protect vulnerable populations during rapid technological expansion.

Why Did xAI Operate Without Permits Initially?

The company's approach mirrors its earlier Colossus I project in Memphis. In both cases, xAI began operating gas turbines before acquiring permits from state agencies. The Mississippi Department of Environmental Quality agreed with xAI's argument that the turbines for Colossus II were exempt from certain regulations because they were classified as mobile and temporary sources. The agency eventually issued a permit, which the NAACP and environmental groups opposed.

"There's no question in my mind that it's a bad faith effort, because they did this once, and eventually had to go get permits, and now they did it again," said Jennifer Danis, federal energy director of the Institute for Policy Integrity at the New York University School of Law.

Conner emphasized that xAI's strategy of building in an already-polluted community and then bypassing legal requirements represents a troubling pattern. "Not only were they going to build this level of pollution in a community that's already faced so much environmental degradation, but they also were like, 'we're just going to skip over the law altogether,'" she stated.

How Are State Officials Responding to Data Center Growth?

Despite the lawsuit's allegations, many elected officials view data centers as engines of economic development. In his February 2026 State of the State address, Tennessee Governor Bill Lee pointed to Oracle's presence in Nashville and xAI in Memphis as evidence of "the best business environment in the country." Lee outlined plans for the state to "both power America and be the catalyst for solving our nation's most complex problems" through AI and quantum computing investments.

In June 2025, Mississippi Governor Tate Reeves announced an accelerator program to foster AI development across the state's higher learning institutions, stating that the investment would help Mississippians acquire skills needed to thrive in a digital economy. Reeves's office did not respond to questions regarding the lawsuit.

What Do Industry Leaders Say About Data Center Responsibility?

Not all data center operators follow xAI's approach. Bill Kleyman, CEO of Apolo AI Launchpad, which delivers AI solutions for manufacturing, construction, and data center industries, emphasized that the industry is diverse and that xAI's practices should not define the entire sector.

"The challenge that we're experiencing is that so much of what we're doing is being lumped into an umbrella. There's different types of operators out there," said Kleyman.

Kleyman outlined the key differences between responsible and irresponsible data center operators:

• Transparency: Good data center operators explain what is being built, how much water and energy will be used, what the construction phases are, and what the community receives in return.
• Energy Mix: Responsible operators use a combination of fossil fuels and renewable sources such as battery storage, hydropower, solar, and wind power.
• Community Benefits: Legitimate data centers provide job creation, tax-base expansion, and infrastructure upgrades to local communities.
• Accountability: Bad operators avoid specifics, hide behind non-disclosure agreements, and simply tell residents to "trust me, it's fine."

What Does This Mean for the AI Industry's Future?

The xAI lawsuit reflects a broader wave of pushback over the health, environmental, and economic impacts of data centers as they proliferate to power the artificial intelligence era. The NAACP partnered with Earthjustice and the Southern Environmental Law Center, alleging that xAI violated the federal Clean Air Act. Earthjustice has previously worked with the NAACP on similar issues such as emission regulations of highly toxic air pollutants and lead in drinking water.

The case also arrives as the compute infrastructure market becomes increasingly central to AI competition. Anthropic recently agreed to pay SpaceX $1.25 billion per month through May 2029 for access to computing infrastructure at Colossus and Colossus II, demonstrating how critical data center capacity has become to AI development. Anthropic's quarterly revenue is expected to exceed $10 billion, underscoring the enormous resources flowing into AI infrastructure.

President Donald Trump's administration has encouraged investments in artificial intelligence and fossil fuels while also undermining environmental justice efforts, adding political complexity to the regulatory landscape surrounding data center development.
