CIOs need to start accounting for AI carbon footprint

AI-summarised brief · reviewed before publication

The article explains that while generative AI is often viewed as a software or productivity tool, its carbon footprint is significant and largely overlooked by CIOs. Data centers consumed 415 TWh of electricity in 2024, projected to rise to 945 TWh by 2030, with AI driving nearly half of that increase. Although data centers will still account for less than 3 % of global electricity demand, the additional power will largely come from natural gas and coal, potentially peaking at 320 million tonnes of CO₂ by 2030. Current per‑prompt estimates are unreliable because emissions vary by model, task complexity, and data‑center location. The article urges CIOs to quantify AI usage within their own carbon inventories to avoid hidden environmental costs.

💡 Why It Matters

  • · Understanding AI’s hidden emissions is essential for accurate corporate sustainability reporting and for preventing a rebound effect that could negate efficiency gains.
