Industry jargon

Ultra Low Emission Zone

Also called: ULEZ The Ultra Low Emission Zone, or ULEZ, is London's road-charging zone for vehicles that do not meet specified emissions standards. It is not a zone reserved for zero-emission vehicles. Compliant petrol and diesel cars can travel in the ULEZ without paying the ULEZ charge. For M1 passenger cars, TfL states that the NOx standard is equivalent to Euro 4 for petrol cars and Euro 6 for diesel cars, with an additional particulate-matter requirement for diesel. Battery electric vehicles meet the relevant tailpipe-emissions standard, but other London road charges can still apply separately.
