Sierra Club: Planned US Data Centers Could Add 618 Million Tons of CO2 by 2030
A Sierra Club analysis, first reported by Bloomberg, projects that US grid emissions could reach 2.1 billion metric tons of CO2 by 2030 if currently planned AI data centers come online as scheduled. That would mark a 42 percent jump from 2025 levels, driven largely by gas-fired power plants built on or near data center sites to bypass grid bottlenecks.
