MILAN (Reuters) - More than a dozen cities and towns across Italy introduced traffic curbs on Wednesday in a bid to cut harmful emissions following a spike in pollution.
A prolonged period of sunny weather with little rain or wind has pushed up air pollution across the country, triggering smog alerts in more than 60 municipalities.
Officials in the northeastern city of Turin, home to Italian automaker Fiat, banned cars built before 2013 from taking to the roads, as did at least 11 other municipalities in the surrounding Piedmont region.
Cities and towns in the neighbouring region of Lombardy, including Milan, had also announced similar curbs for Wednesday, but subsequently temporarily lifted the order because a public transport strike risked leaving locals stranded.
"(Milan) is surrounded by mountains so with environmental conditions like today, when there is no wind, the air gets stuck in the middle of the valley," said Renato Grampa, an engineer. "Heating systems and car emissions create this bubble of smog."
Further south, the Tuscan city of Florence and seven nearby towns banned highly polluting vehicles from their streets for the next five days.
The Air Quality Index https://aqicn.org/map/world showed Italy was one of the most highly polluted places in western Europe on Wednesday. Many of the more populous areas posted levels deemed unhealthy, with a top reading of 170 registered in Tuscany.
But Italy was still considerably better off than large swathes of Asia, with the Indian capital Delhi, one of the world's most polluted cities, scoring above 300 on the index.
