A new analysis by the Sierra Club estimates that by 2030, the expansion of data centers in the United States could result in a 42% increase in carbon dioxide pollution from the US power sector compared to 2025 levels. This projection indicates that the output from pending data center builds could lead to 2.1 billion metric tons of CO2 in the atmosphere by the end of the decade.
This anticipated rise in emissions is primarily driven by the construction of new fossil fuel infrastructure to meet the electricity demands of data centers. The Sierra Club warns that such an increase would effectively negate 15 years of progress made in reducing greenhouse gas emissions, pushing back efforts to combat climate change.
Jeremy Fusher, principal advisor for climate and energy at the Sierra Club, stated that the numbers 'boggle our minds.' The report suggests that by 2030, US data center buildouts could be responsible for as much carbon dioxide as the entirety of Mexico's current output. The CO2 emissions from electricity generation are expected to increase by 618 million tons by the end of the decade if planned AI projects are constructed, which is roughly equivalent to the carbon pollution from the electricity use of 128,788,523 homes in a year.
The Sierra Club's estimate is higher than some previous projections from other groups. For instance, a study published by academic researchers in June forecast that electricity demand from data centers and crypto mines could push up power sector emissions by 28% by 2030 when compared to a scenario without data center growth.

A Sierra Club analysis projects US power sector carbon dioxide pollution could increase by 42% by 2030 compared to 2025 levels, driven by new fossil fuel infrastructure for data centers. This increase would negate 15 years of greenhouse gas reductions, raising concerns about climate goals.
A Sierra Club report estimates that by 2030, US data center carbon emissions will equal Mexico's total output, negating 15 years of greenhouse gas reduction efforts. This projection indicates a 42% increase in CO2 from the US power sector by 2030 compared to 2025 figures, primarily driven by new data center builds.
