Google’s AI Boom Pushes Electricity, Water, and Emissions to Record Highs

Google’s latest environmental reporting, detailed in Axios’s June 2026 coverage of the company’s newest sustainability data, shows electricity consumption, water use, and greenhouse gas emissions all reached record highs as the company accelerated its AI infrastructure buildout . Earlier reports covering Google’s 2024 fiscal-year data — published in the company’s 2025 Environmental Report — also showed significant increases, with emissions up 48% compared to 2019 .

The Record Highs: 2025 Data

The most recent figures, reported by Axios in June 2026, show three key metrics hitting new peaks :

• Electricity demand surged 37% year-over-year, roughly 3.5 times higher than in 2019 .
• Greenhouse gas emissions rose 18% year-over-year, which Axios described as the largest annual increase on record .
• Water consumption climbed 34% to 10.9 billion gallons, more than double the 2021 level .

These increases accelerated sharply. The previous year’s data showed a 27% rise in electricity demand and an 11% rise in emissions . Google’s total greenhouse gas emissions in 2024 (reported in the 2025 Environmental Report) were 51% higher than the 2019 baseline .

What Google Says Caused the Increases

Google attributed the rising resource consumption to the explosive growth of AI and the corresponding expansion of its data center infrastructure . The company has previously linked rising emissions to the increasing energy needs of its data centers, which have been intensified by AI computing demands . Axios reported that the record levels came as Google “raced to build more AI infrastructure” . A significant portion of the emissions increase in 2025 was driven by the manufacturing of AI hardware, including chips and servers .

Mitigation Steps Google Reported

Despite the overall growth in resource use, Google reported several mitigation achievements :

• Reduced data center energy emissions by 12% in 2024, even as electricity demand for its data centers grew by 27% . The company attributed this to new clean energy projects coming online and a 6x increase in computing power per unit of electricity over five years .
• Replenished over 7 billion gallons of water in 2025 through 165 projects across 97 watersheds . This is part of a goal to replenish 120% of its freshwater consumption by 2030 .
• Signed contracts for over 8 gigawatts (GW) of clean energy in 2024, its largest annual total .
• Developed more efficient AI chips, with Google claiming its new Ironwood TPU is nearly 30 times more power efficient than previous generations .

Broader Industry Context

Google’s environmental pressures mirror a wider struggle across the tech industry as AI deployment accelerates.

Rising Emissions Across Big Tech: A wave of sustainability reports published in mid-2025 showed that AI-driven energy demand was making it harder for major technology companies to meet their net-zero climate goals . The NewClimate Institute’s Corporate Climate Responsibility Monitor noted that “emission targets seem to lose meaning as actual emissions surge” .

Investor and Community Pressure: More than a dozen investors have pressed Amazon, Microsoft, and Google for detailed information on water consumption and energy use at their U.S. data centers . Local community opposition, driven by concerns over water, energy, pollution, and land use, has led to the halting of several multibillion-dollar data center projects for these companies .

Rising Climate Litigation: Data centers are becoming a growing target of climate-related legal cases globally. A review of roughly 3,600 climate-related legal actions by the London School of Economics found an increase in cases contesting the energy sources, water usage, and air pollution associated with data centers .

Scrutiny of Emissions Accounting: Google’s own emissions figures have been challenged. A report by the nonprofit Kairos Fellowship claimed Google’s emissions actually rose by 65% from 2019 to 2024, not the 51% the company reported, and that total emissions have surged 1,515% since 2010 . The discrepancy centers on how companies account for renewable energy credits and supply-chain (Scope 3) emissions .
