A deep regulatory wave
Low emission zones (LEZ) restrict the most polluting vehicles' access to city centres. The movement is accelerating: according to the CLARS / Arval observatory, Europe had more than 320 LEZs in 2022, with a projection of around 507 by 2025. No longer a local exception — a continental norm.
A fragmented regulatory landscape
LEZs sit within a broader set of urban vehicle access regulations (UVARs): tolls, pedestrian zones, limited-traffic zones. According to the European Commission, 73% of UVARs in Europe are low- or zero-emission zones, and new harmonised datasets on these rules apply from January 2025. The difficulty for a carrier: each city has its own rules, hours and permits.
Operational impacts
- Some vehicles can no longer access certain zones at certain times;
- Fleet renewal (cleaner vehicles) becomes a strategic investment;
- Planning must factor in zones and authorised access windows;
- The risk of fines and immobilisation rises without anticipation.
How to anticipate
Map the LEZs in your operating areas and their start dates. Adapt vehicle assignment to zones (the cleanest downtown). And build these constraints into planning, so you don't send an unauthorised vehicle into a restricted zone.
