Greenhouse gases from data center boom could outpace entire nations

WIRED found that gas-fired power projects tied to 11 U.S. data center campuses could emit over 129 million tons of greenhouse gases a year.

The largest planned projects include xAI’s Colossus site and a proposed Microsoft-linked campus, underscoring the scale of the buildout.

The findings suggest the AI and data center boom is driving major new fossil-fuel infrastructure, with climate impacts that can rival entire countries.
