This talk presents insights from an 18-month investigation into the supply chains of AI, funded by a British Academy grant awarded to Dr Ana Valdivia. During this time, Ana conducted ethnographic research in Chile and México, which have emerged as key hubs for data centres in Latin America. Dr Valdivia’s research introduces a theoretical framework called the ‘supply chain capitalism of AI,’ uncovering the minerals, commodities, and facilities that are crucial to AI development today. This study examines the interactions and controversies surrounding data centres, involving communities, governments, and private actors. By integrating digital methods and interviews, it proposes a transdisciplinary approach to analysing the political and environmental impacts of AI supply chains. This research aims to contribute to both global and local debates about the environmental impact of AI from critical data studies lens.
