Methode en kanttekeningen
De Index combineert vijf metingen per stad: groenruimte per inwoner, hoe heet de heetste wijken worden, en drie luchtvervuilers (PM2.5, PM10, NO2). Een stad wordt per meting van eerste tot laatste geplaatst en die plaatsen worden gemiddeld, waarbij groenruimte dubbel telt. Lager is beter.
Hitte is landoppervlaktetemperatuur, niet luchttemperatuur. Luchtkwaliteitswaarden zijn modelschattingen. Groenoppervlak is de door satelliet gedetecteerde vegetatieomvang, niet de boomhoogte.
