The adoption of temporary emergency measures aimed at preventing and containing atmospheric pollution will be carried out on MONDAY and THURSDAY, except on holidays.
ORANGE LEVEL: activated after 4 consecutive days of exceeding the values of the reference station based on the check carried out on MONDAY and THURSDAY (control days). The temporary measures come into effect from the 5th day of potential exceeding and remain in force until the conditions of exceeding persist and in any case not beyond the next control day.
Limitation of circulation in the Green Belt LTZ (in addition to vehicles already affected by permanent and programmed limitation) for:
vehicles powered by Euro 3 gasoline
vehicles powered by Euro 4 diesel
mopeds and (3 and 4-wheeled) motorcycles powered by Euro 2 diesel
freight vehicles powered by Euro 4 diesel (N1, N2, and N3 categories);
RED LEVEL: activated after 10 consecutive days of exceeding the values of the reference station, based on the verification carried out on MONDAY and THURSDAY (control days). Temporary measures come into force from the 11th day of potential exceedance and remain in force until the exceedance conditions persist and in any case not beyond the next control day.
Limitation of circulation in the Green Zone ZTL from 7.30 am to 8.30 pm (in addition to vehicles already subject to permanent and/or scheduled limitation) for:
vehicles powered by Euro 5 and 6 diesel
freight vehicles powered by Euro 5 and 6 diesel (N1, N2, and N3 categories)
The transition from one level to the next or the previous one (including the return to the green level "no alert") can be evaluated on the "control days", as well as on the basis of the criteria set out above, also taking into account the actual degree of criticality in progress (referring to the data measured by the monitoring stations), the phenomenological situation (e.g., meteorological evolution, transport of natural origin dust) and the urban context (e.g., transport strikes, major events).
As established by national and regional regulations, in order to prevent and contain air pollution, five "Eco-Sundays" are scheduled every year. The 2022-23 events have ended.
During Eco-Sundays - in the Green Zone - private traffic circulation (with some exceptions) is prohibited from 7.30 am to 12.30 pm and from 4.30 pm to 8.30 pm.
