估算AI数据中心的排放增长
Estimating the growth in emissions from AI data centres
AI总结：
本研究采用先进生命周期评估模型，结合IEA与麦肯锡情景，量化AI数据中心扩张的排放，发现AI行业推崇的情景会使总排放大幅上升，隐含碳分量显著。
AI中文摘要：
智能体AI的出现正推动数据中心扩张实现前所未有的增长。我们采用针对AI服务器运营及隐含排放的最先进生命周期评估模型，估算AI数据中心的总CO₂排放随之产生的增长。本研究的主要贡献是利用国际能源署（IEA）和麦肯锡（McKinsey）的情景，严格量化AI数据中心扩张预计产生的排放。我们表明，AI行业所推崇的情景将导致总排放急剧上升，且隐含碳分量相当可观。
英文摘要：
The advent of agentic AI is driving an unprecedented growth in data centre expansion. Using state-of-the-art life cycle assessment models for operational and embodied emissions from AI servers, we estimate the ensuing growth in overall CO2 emissions of AI data centres. The main contribution of this work is a rigorous quantification of emissions arising from projected AI data centre expansion using scenarios by the IEA and McKinsey. We show that the scenarios promoted by the AI industry would result in a dramatic rise in overall emissions and that the embodied carbon component is considerable.
