Mètode i ressalves
L'Índex combina cinc mesures per ciutat: espai verd per habitant, com de calents es posen els barris més càlids i tres contaminants de l'aire (PM2.5, PM10, NO2). Cada ciutat se situa de la primera a l'última en cada mesura i aquestes posicions es promitgen, amb l'espai verd comptat dues vegades. Més baix és millor.
La calor és la temperatura de la superfície terrestre, no la temperatura de l'aire. Els valors de qualitat de l'aire són estimacions de models. L'àrea verda és l'extensió de vegetació detectada per satèl·lit, no l'alçada dels arbres.
