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.

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.
