GoKawiilSierra 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.
GoKawiil's interpretation of the reporting above, not reported fact.
The projection suggests that gains from years of emissions-cutting policy could be reversed by the AI buildout's reliance on fossil-fueled power rather than clean grid capacity, according to the Sierra Club's Jeremy Fisher. Local opposition and financial pressures are reportedly causing some data center projects to be cancelled, which could blunt the scale of emissions increases, though the eventual outcome remains uncertain.
- Sierra Club estimates planned data centers could push 2030 US grid emissions to 2.1 billion metric tons.
- That would be a 42% rise over 2025, adding roughly 618 million tons of CO2.
- Many projects rely on on-site gas plants due to grid bottlenecks, though rising cancellations could offset some impact.
EcoFlow DELTA Pro Solar Generator — If data center growth is straining the grid and spiking emissions, it's worth taking personal energy use into your own hands with a home solar battery system like this one. It lets you store clean solar power and reduce reliance on a grid increasingly burdened by gas-fired AI infrastructure.
