Climate and air: anti-smog rules inside the ring roads

Traffic restrictions

Municipal ordinance no. 102/2026 bans, Monday to Friday from 8:30 to 18:30, petrol, LPG and methane cars up to Euro 2, diesel cars up to Euro 4 and mopeds and motorcycles up to Euro 2 inside the ring roads and in the Parco Area delle Scienze (university campus). Every Sunday in the period except 1 November is an ecological Sunday: during the same hours the ban extends to Euro 5 diesels. The restrictions do not apply on 8 and 25 December, 1 and 6 January and on public transport strike days; a list of streets stays open and vehicles enrolled in MOVE-IN may circulate on weekdays.

Emergency measures and heating

Arpae checks the PM10 forecast on Mondays, Wednesdays and Fridays and updates the bulletin after 11:00: when exceedances are forecast, from the next day the ban inside the ring roads runs from 8:00 to 19:00 and includes Euro 5 diesels, with bans on slurry spreading and on biomass heaters below "5 stars" where another system exists. Heating may be switched on from 1 November, with caps on indoor temperatures in homes, offices and shops.

A measure specific to Parma: if a city station reaches 25 exceedances of the daily PM10 limit in the year, a ban on biomass heaters where an alternative exists, traffic checks increased by 25% and a limit of 13 hours a day of heating, between 5:00 and 23:00, apply automatically.
