If you are going to have to pay a charge to enter a Clean Air Zone with your current vehicle, you may want to consider hiring a vehicle that complies and will not incur a charge.
The Europcar UK car and van fleet meets the Euro 4 Emission Petrol Standards or Euro 6 Emission Diesel Standards making them exempt from charges within Clean Air Zones.
Some cities are looking to go further and create Ultra Low Emission Zones (ULEZ) or Zero Emission Zones (ZEZ) where a total ban of non-compliant vehicles may be introduced instead.
London is the only ULEZ in the UK, up to but not including the North and South Circular roads. The ULEZ standards for London are:
Euro 3 for motorcycles, mopeds, motorised tricycles and quadricycles (L category)
Euro 4 (NOx) for petrol cars, vans, minibuses and other specialist vehicles
Euro 6 (NOx and PM) for diesel cars, vans and minibuses and other specialist vehicles
Some cities are looking to go further and create Zero Emission Zones (ZEZ) which will be for vehicles with no emissions at all. This is for electric vehicles only. Oxford is the first city to launch a ZEZ, and all the details can be found here, including a map and all the charges.
