How London scores as a location

Water stress index · median of 111 data centers: 49/100 · average
Social friction index · median of 111 data centers: 96/100 · high

Both describe the place, not the operators: a higher water score means scarcer water, a higher friction score more of the conditions that tend to come before local opposition. The nearby tool reads the single nearest facility, so its figures can differ from these medians by a few points. Methods: water stress index · social friction index.
