Here’s a shocking truth: Elon Musk, once a vocal advocate for combating climate change, is now undermining his own legacy with a controversial AI venture that’s spewing millions of tons of greenhouse gases into the atmosphere. But here’s where it gets controversial: while Tesla proudly claims to have avoided 32 million metric tons of CO2 emissions, Musk’s xAI is single-handedly erasing a significant portion of that progress—all to power an AI model that lags behind its competitors. And this is the part most people miss: the environmental and human costs are staggering, with communities of color bearing the brunt of the pollution.
In 2024, xAI constructed its Colossus supercomputer in South Memphis, Tennessee, and faced a power supply challenge. Instead of pursuing sustainable solutions, the company installed 35 methane gas turbines without the necessary environmental permits or pollution controls. The Southern Environmental Law Center (SELC) revealed that xAI operated 33 of these turbines while only permitted for 15, exploiting a loophole by classifying them as ‘non-road engines’ to bypass the Clean Air Act. Bold move or reckless disregard? You decide.
After facing public backlash, xAI’s response was astonishing: they planned to replicate this unlawful strategy at their next facility in Southaven, Mississippi. True to their word, they installed 27 more unpermitted turbines, generating up to 495 megawatts—equivalent to a conventional power plant. Combined with the Memphis site’s 422 MW, xAI now operates nearly a gigawatt of unpermitted fossil fuel generation. Even after the EPA closed the loophole in January 2026, thermal drone footage from February showed xAI continuing to burn gas in Mississippi.
The numbers are alarming: xAI’s facilities could emit over 6 million tons of greenhouse gases annually, along with 1,300 tons of harmful air pollutants. At the Memphis site alone, the turbines release 1,200 to 2,000 tons of nitrogen oxides (NOx) per year, likely making xAI the largest industrial source of smog-forming pollution in the Memphis metropolitan area. A TIME investigation found that nitrogen dioxide levels near the facility surged by 79% compared to pre-xAI levels.
But here’s the real kicker: xAI’s emissions could erase up to 59% of Tesla’s actual climate impact, according to independent estimates. That’s right—one man’s AI project could undo nearly half of the environmental benefits Tesla claims to deliver globally. And for what? To power an AI model, Grok, that underperforms compared to competitors like Google’s Gemini and OpenAI’s ChatGPT, while costing more to run.
The human toll is equally devastating. Both xAI facilities are located in or near predominantly Black communities already burdened by pollution. Boxtown, the Memphis neighborhood closest to Colossus, had a cancer risk four times the national average before xAI arrived. A SELC study estimated that the turbines at Colossus 2 alone could cause $30 to $44 million in annual health damages, including premature deaths, asthma, and heart attacks. NBC News reported that children in Southaven have developed respiratory problems, and families have been forced to abandon their homes due to the relentless noise.
In February 2026, the NAACP, SELC, and Earthjustice issued a notice of intent to sue xAI under the Clean Air Act. At a public hearing in Southaven, hundreds of residents attended, and not a single person spoke in xAI’s defense. Attendees wore shirts reading, ‘Not all money is good money.’
Here’s a thought-provoking question: Is Musk’s pursuit of AI innovation worth the environmental and human cost? Compare xAI’s approach to Google’s, which invested $4.75 billion in clean energy infrastructure, including a 1 GW solar deal in Texas. Microsoft and Amazon are also pouring billions into renewables and nuclear energy. Musk, meanwhile, chose the cheapest, most environmentally destructive option—twice—while leading a company built on the promise of clean energy.
Tesla’s mission to accelerate sustainable energy has been a cornerstone of its brand, but Musk’s actions at xAI make this mission seem more like a marketing ploy than a genuine commitment. Sixty-two unpermitted gas turbines, 6 million tons of CO2, and communities suffering from pollution and noise—all for a subpar AI model. The NAACP’s lawsuit is looming, the EPA has closed the loophole, and public opinion is firmly against xAI.
So, we ask you: Is this the legacy Elon Musk intended to leave? And is it one we should accept? Let us know your thoughts in the comments.
