FRANKFURT: Data centres, whose expansion is being fuelled dramatically by the artificial intelligence boom, have a far bigger carbon footprint than previously estimated, a study said Tuesday. The sprawling, power-hungry sites, used to store critical IT infrastructure like servers, are being built worldwide by companies and countries as AI applications gobble ever greater computing power. This has helped to boost their greenhouse gas emissions, with a new study by Allianz Trade estimating the centres emitted 286 million tonnes of carbon dioxide in 2025. This is 57 percent higher than estimates by the International Energy Agency, according to the group, which is the trade credit insurance arm of global insurer Allianz. AI already accounts for between 15 and 20 percent of electricity consumption at data centres, and this share could climb to 40 percent by 2030, the report said. &quot;Data centres are evolving from a marginal factor into a structural driver of electricity demand in many regions,&quot; said Patrick Hoffmann, senior climate economist at Allianz. Without steps to decarbonise power grids, data centre emissions would more than double by 2030, leading to an estimated $154 billion in annual climate damages -- up from $68 billion today, the report said. Climate damage related to AI workloads could exceed $50 billion by 2030, it said. Data centres also putting huge strain on natural resources -- they could require 1.3 to 1.8 trillion litres of water by 2030, comparable to Switzerland&#39;s annual consumption, the report said. The same computing power can generate very different emission levels depending on the source of the electricity used. In India, emissions linked to electricity exceed 600 grams of CO2 per kilowatt-hour (kWh), compared with less than 30 grams in Norway or Sweden, where power generation is largely decarbonised. According to Allianz Trade, nearly 70 percent of global data centre emissions are currently concentrated in the United States and China, the world&#39;s AI leaders.

Artificial Intelligence

A new study says AI-driven data centers emit far more carbon than previously estimated, with emissions, electricity demand, water consumption and climate costs expected to rise sharply by 2030.
