What happened
The Sierra Club's internal analysis found that the construction of fossil-fueled power plants to run AI data centers could undo 15 years' worth of greenhouse gas reductions from US electricity generation. The analysis estimated that the US power sector would emit 2.1 billion metric tons of carbon dioxide by 2030, a 42% increase from 2025 levels. Many data center developers are turning to natural gas to meet the immense electricity demand, relying on power sources that are both on and off the grid.

The analysis estimated that the US power sector would emit 2.1 billion metric tons of carbon dioxide by 2030, a 42% increase from 2025 levels.
Many data center developers are turning to natural gas to meet the immense electricity demand, relying on power sources that are both on and off the grid.
The bulk of the expected emissions by 2030 would come from sources that are not directly linked to the grid, often built by tech companies to avoid the long wait for a connection.
These could exceed 460 million tons, roughly the same as the annual emissions of Mexico.
Why it matters
The increase in emissions from AI data centers could undo 15 years of progress in reducing greenhouse gas emissions from US electricity generation. This could have significant implications for the environment and public health. The Sierra Club's analysis highlights the need for more sustainable and renewable energy sources to power AI data centers.
