Google — self-build
Who approved it
Chile's First Environmental Court revoked the environmental permit in January 2024, finding the groundwater assessment inadequate; Google refiled with an air-cooled design in 2025

The only case worldwide where a court has voided a hyperscaler's environmental permit specifically over aquifer impacts. Santiago has been in a structural drought for more than a decade, and the project became a national test of environmental review.

Water and air figures are modelled from disclosed capacity, not measured — site-level
error is roughly ±40%. Diesel backup generators are not counted, so on-site figures are floors.
