Big Tech Data Centers Could Add 101.5 Million Tons of CO2 a Year as Utilities Build More Gas
3 articles · Updated · Financial Times · Aug 16
Summary
101.5 million tonnes of CO2 a year could come from 60 large planned US data centers by Amazon, Microsoft, Google and Meta once fully operational, equal to about 7% of 2025 US power-sector emissions.
Surging electricity demand is driving that increase: three-quarters of utilities serving the projects are planning or building new gas-fired capacity, and a third of those with coal plants are delaying retirements.
17% of those utilities have explicitly told regulators new gas plants are needed for specific hyperscale data centers, while more than one-third of US gas capacity now in development is slated for on-site data-center power.
The build-out is already showing up in corporate disclosures, with Amazon reporting emissions up 16% in 2025, Microsoft 25%, and Alphabet’s adjusted emissions 18% despite heavy clean-energy purchases.
The trend threatens to slow or reverse US power-sector decarbonization as AI infrastructure drives about 55% of utility load-growth forecasts over the next five years and clean-energy additions face bottlenecks.
As AI data centers revive coal and gas, will your local utility bill skyrocket to fund Big Tech's massive energy appetite?
With hyperscale campuses now building their own gas plants, is the dream of a completely green tech industry officially dead?
Could the rapid expansion of AI infrastructure quietly erase years of environmental progress by forcing a massive return to fossil fuels?
The Data Center Energy Crisis: How AI-Driven Growth Is Threatening U.S. Climate Goals, Grid Stability, and Public Health (2025–2026)
Overview
The explosive growth of U.S. data centers in 2025–2026 has caused record-breaking electricity demand, forcing utilities to delay retiring old coal plants and rely more on fossil fuels. This shift threatens national climate goals and leads to increased pollution, with data centers projected to cause hundreds of thousands of asthma cases and over a thousand premature deaths each year by 2030. As tech giants rapidly expand AI infrastructure, their carbon emissions soar, while utilities pass massive infrastructure costs to consumers, driving up electricity bills and deepening the energy affordability crisis. Mounting environmental and economic impacts have sparked strong community backlash, resulting in local bans, project cancellations, and new state restrictions. In response to grid strain, federal regulators have begun urgent interventions, but the lack of a unified national policy continues to fuel local resistance and regulatory uncertainty.
