Policy-event dataset on the environmental governance of AI and data-centre infrastructure

Abstract

This record contains Supplementary Data 1–7 of the associated article on the environmental governance of artificial-intelligence and data-centre infrastructure: the final event-level policy corpus (Supplementary Data 3, Supplementary Table S3), the full-sample reliability records (Supplementary Data 1, Supplementary Table S1), the fixed-frame search protocol and query log (Supplementary Data 2, Supplementary Table S2), the macro-category and jurisdiction-level distributions (Supplementary Data 4, Supplementary Table S4), the analytical specifications and resampling settings (Supplementary Data 5, Supplementary Table S5), the illustrative-case source register (Supplementary Data 6, Supplementary Table S6) and the numerical source data underlying Figs. 1–4 (Supplementary Data 7). The final corpus comprises 114 retained policy events (Dataset B); Dataset A comprises the 63 retained events of the screened baseline. The event classifications describe coded policy orientations and governance approaches. They do not measure realized environmental outcomes. Base-map boundaries used for Fig. 1 are from Natural Earth (public domain) and are not redistributed here.
