xAI's Memphis data center plans to emit over 6.4 million tons of CO2 annually, rivaling emissions from 30 gas plants. Microsoft's Chevron-backed West Texas project could release 11.5 million tons yearly—more than Jamaica's total emissions. These behind-the-meter gas projects, bypassing grids to power AI hubs, face community backlash and legal challenges. Energy experts warn inefficient turbines, chosen for speed over sustainability, may emit up to 60% of permitted levels.

While companies like Oracle claim emission reductions, permit documents reveal Stargate AI infrastructure could collectively emit 24 million tons annually. Critics argue this "bridge fuel" strategy locks in fossil fuel dependence, undermining net-zero pledges.
