Méthode et réserves
L'Index combine cinq mesures pour chaque ville : l'espace vert par habitant, la chaleur de ses quartiers les plus chauds et trois polluants atmosphériques (PM2.5, PM10, NO2). Chaque ville est classée de la première à la dernière place pour chaque mesure, et ces places sont moyennées, l'espace vert comptant deux fois. Plus bas, c'est mieux.
La chaleur désigne la température de surface, pas la température de l'air. Les valeurs de qualité de l'air sont des estimations de modèle. La surface verte est l'étendue de végétation détectée par satellite, pas la hauteur des arbres.
