## AI overview

The Sierra Club estimates that planned US AI data centers could add 618 million metric tons of power-sector CO₂ emissions from 2025 to 2030, a 42% increase that would bring 2030 emissions to 2.1 billion metric tons and reverse 15 years of electricity-sector cuts. It says the projected impact is two to four times its estimate from 18 months earlier. Data centers' off-grid power sources could add more than 460 million metric tons, though projections vary widely: renewables could curb emissions, and many planned facilities may be delayed or canceled. For comparison, Rhodium Group's highest-emission scenario still has 2040 power-sector emissions 24% below 2025 levels. The excerpt also cites a planned Texas data center powered by a 7.65-gigawatt gas plant permitted to emit up to 33 million tons of CO₂ annually. These estimates are uncertain because buildout and power sources remain unsettled.

## Source excerpt

In a report obtained by Bloomberg, the environmental nonprofit Sierra Club estimates that planned US AI data centers would add 618 million metric tons to the power sector's carbon emissions between 2025 and 2030, a 42% increase. The figure would effectively reverse 15 years of greenhouse gas reductions from electricity generation. Read Entire Article
