“Planned / under construction” counts inventory facilities with a disclosed MW figure; “Announced pipeline” sums the tracked large projects (≥ 100 MW or ≥ USD 1 bn) as stated by developers, two different sources, so they don't match. “Best” / “worst” compare only the selected countries; for the water and friction indices the tags say “lowest” / “highest”, since they describe exposure, not merit. Capacity and PUE: disclosed values only (sites in brackets). Water & friction: derived indices, median over each country's data centers (method). Free cooling: NASA POWER 2015–2024. Carbon: Ember.
