Dati inquietanti emergono da uno studio di Transport&Environment sull’inquinamento atmosferico prodotto dalle grandi navi passeggeri. Da soli i 47 alberghi galleggianti della Carnival, il primo operatore mondiale, inquinano ben venti volte di più di tutte le auto che troviamo sulle strade dell’UE. A preoccupare ulteriormente gli studiosi è che la maggior parte delle emissioni avviene nei porti, vicino ai grandi centri abitati, dove le imbarcazioni restano ancorate per giorni, senza spegnere i motori, necessari a far funzionare i servizi di bordo per i passeggeri.
Tra le 50 città costiere più inquinante dalle emissioni delle navi da crociera dieci sono italiane, con Venezia al primo posto. Nella laguna veneta stazionano regolarmente 68 grandi navi, ferme con i motori accesi per quasi 8'000 ore.
