These environmental measures have been suspended with effect from Monday 10 December, following improvement in the quality of the air. Milan city hall however invites residents to avoid using motor vehicles when possible and to use public transport instead.
Cremona, Lodi, Mantova, Monza and Pavia also affected.
Four consecutive days of excessive levels of PM10 particles in the air have automatically triggered the “first level” of preventive measures, including traffic restrictions.
The measures include a ban on the use of private cars with Euro-4 grade diesel motors every day (including weekends) from 08.30 to 18.30. Homes and shops must set thermostats to not exceed 19°C, and wood-burning stoves may not use fuel with two stars or fewer. Drivers must also stop their engines when parked, and not use them to run the heating in a stationary vehicle.
The measures will remain in force until atmospheric pollution has dropped to an acceptable level for two consecutive days.
The restrictions apply to comuni with over 30,000 residents, plus a few smaller towns which have adhered voluntarily; they are listed in this document published by Lombardy regional government.
The rules for the protection of the environment are set out in the Air Protocol signed by the four administrative regions of the Po basin: Lombardy, Emilio Romagna, Veneto and Piedmont.
