China, Hong Kong, Japan and South Korea, measure by measure. EU-wide rules are listed once. National and regional or local rules are shown side by side, each with its status, effective date and source.

PUE targets for data centres (national policy)
targetenergy efficiency
In force · effective 2021
New large DCs must meet PUE<=1.25 (national hubs) / <=1.3 elsewhere, plus increasing renewable-energy use (target ~80% green-power utilisation for hub DCs by the early 2030s).
Typical effect of this kind of measure: Sets efficiency rules a data center must meet, e.g. a PUE ceiling or mandatory KPI reporting. Can force cooling/design changes and rule out inefficient builds.
Directs DC siting to designated clusters; efficiency (PUE) and renewable conditions apply; siting/fiscal incentives available within hubs.
Typical effect of this kind of measure: Shapes demand and siting (data localization, cloud-first, digital plans). Indirect: it drives where capacity is needed rather than regulating the facility itself.
Subsidies/support for new regional data centres and related power/network infrastructure.
Lowers the cost of building outside the Tokyo/Osaka corridor: government subsidies support new regional data centres (e.g. Hokkaido, Kyushu) and related power/network links.
Restrictions on metro-Seoul data-centre grid connections
regulationgridin friction index
In force · effective 2023
Large DCs near Seoul face stricter/deferred grid-connection review; distributed-energy obligations for large users; incentives to locate in non-capital regions.
Typical effect of this kind of measure: Controls whether: and how fast: a data center can get grid power. Can delay, cap or block new capacity, and may force on-site generation or demand commitments.
