How it's computed : Overall score: weighted mean of 1–5 sub-scores scaled to 100 — Quality 45, Price 30, Security 25. Separate environmental score: Electricity 50, Water 50 (estimates, CO₂ derived from electricity). Missing sub-score = excluded and weights renormalized ('partial data'). Never influenced by affiliation. Methodology
