Environmental lawyer Erin Brockovich has launched a campaign against the rapid expansion of AI datacentres, focusing on hidden environmental risks including PFAS contamination — the same pollutant that made her famous in the 1993 PG&E case. She's drawing direct parallels between that battle against a wealthy corporation and her current fight against the tech industry's largely unregulated expansion. The campaign highlights how AI infrastructure's water and energy demands create environmental liabilities that communities bear while companies capture profits. This matters because datacentres are expanding faster than regulatory frameworks can keep up, and Brockovich's involvement is already elevating public awareness of environmental costs typically buried in infrastructure policy.
