Overview
- The Infrastructure Decree amendment postpones the Euro 5 diesel circulation ban in Piemonte, Lombardia, Veneto and Emilia-Romagna from October 2025 to October 2026.
- Municipalities with fewer than 100,000 inhabitants are exempted under the revised criteria, up from the previous 30,000-resident threshold.
- After the October 2026 deadline, regions may forgo structural bans by adopting compensatory emission-reduction measures in their air-quality plans.
- Local anti-smog ordinances remain in force, as demonstrated by Genoa’s weekday ban on Euro 4 and older diesel vehicles since July 1.
- Italy still faces EU infringement procedures over NO₂ and PM10 exceedances and must finalize updated regional air-quality plans under the amended decree.
