UN Report: Data Centers' Environmental Footprint Approaches Nation-Sized Levels by 2030
A United Nations report highlights that data centers' energy use could triple, consuming 935 trillion watt-hours by 2030, largely driven by AI. This surge will result in carbon emissions comparable to that of several large countries, raising significant concerns about sustainability and resource allocation in the tech industry.

According to a United Nations University report, global data centers consumed 448 trillion watt-hours of electricity in 2025, producing 189 million tons of carbon dioxide. Projections indicate that by 2030, data centers will account for nearly 3% of global electricity use, increasing to 935 trillion watt-hours, with AI driving 40% of this demand.
The environmental impact includes a projected doubling of water consumption to 9.3 trillion liters and an increase in carbon emissions to 399 million tons. Concerns arise as data center growth may exceed local resource limits, exemplified by Ireland's scenario where data centers surpassed total household electricity usage. The report underscores the urgent need for transparency in energy consumption and environmental impact across the data center industry.
