Umea in Svezia e Tampere in Finlandia sono le città d'Europa con l'aria più pulita. È quanto emerge da una classifica stilata dall'Agenzia europea dell'ambiente (AEA). Zurigo si piazza al 54esimo rango, Basilea al 95esimo, mentre Lugano è 161esima.
Tampere in Finlandia
Sul podio, alle spalle delle due città nordiche, troviamo Funchal, sull'isola portoghese di Madeira. A seguire la capitale estone Tallinn e la norvegese Bergen, con livelli di inquinamento da polveri sottili da 4,2 a 4,6 microgrammi per metro cubo. In confronto, a Zurigo ne sono stati misurati 8,59, a Basilea 9,39 e a Lugano 10,65.
8 europei su 10 esposti alle polveri fini
Telegiornale 21.01.2021, 13:30
Per stilare la classifica l'AEA ha valutato l'inquinamento da polveri sottili (PM2.5) in 323 città d'Europa. In una nota, gli autori rilevano che in 127 città la qualità dell'aria è considerata buona, in 73 cattiva e in mezzo ci sono 123 località che presentano un inquinamento moderato.
La qualità dell'aria in Europa è migliorata notevolmente negli ultimi dieci anni, in parte grazie alla riduzione delle emissioni nei trasporti e nel settore dell'approvvigionamento energetico.
