What the evidence says

Key findings

01
How it operates

Emissions standard · Moratorium · Siting & permitting

Caps or standardizes the greenhouse-gas and pollution footprint a data center is allowed to produce. Check whether the policy creates, changes, or removes a development pause or prohibition, and which facilities and approvals it covers. Sets where and how a data center can be built, and which authority and reviews can accelerate or block a project.

02
Issues named in the record

Carbon · Siting & Land Use
