New Data Centers in the US Set to Wipe Out 15 Years of Greenhouse Gas Reductions

A recent analysis by the Sierra Club reveals that new data centers in the United States, powered by gas plants, may undo nearly 15 years of hard-earned greenhouse gas reduction efforts. According to Bloomberg, the U.S. energy grid is projected to emit 2.1 billion metric tons of carbon dioxide by 2030, a significant increase from 2025, which was already a near-record year for U.S. carbon emissions.

If the AI industry follows its current plans, emissions could rise by 42 percent over the next five years, amounting to an estimated 618 million extra tons of CO2 compared to 2025 levels.

Sierra Club climate and energy advisor Jeremy Fisher expressed shock at these figures, highlighting the environmental consequences of data center developers' reliance on fossil fuel-based power plants. Projects such as Elon Musk’s 1.2 gigawatt data center near Memphis are already contributing to local air pollution through the use of methane generators, which reportedly violate local permitting and federal environmental regulations.

However, there is a glimmer of hope for those concerned about clean air. The number of data center projects in jeopardy of cancellation is growing as grassroots organizing and financial pressures mount. Opposition from activists could have a significant impact beyond local communities, as canceled hyperscale facilities help maintain cleaner air nationwide. As such, activists in the fight against data centers should remain vigilant, as the benefits of canceling such projects extend well beyond their immediate surroundings.
