London’s Ultra Low Emission Zone (Ulez) will be expanded to cover the entire city under plans announced by mayor Sadiq Khan to cut pollution and congestion. Mr Khan has asked Transport for London (TfL) to consult on extending the scheme’s boundary from the North and South Circular Roads to the whole of Greater London by the end of next year.
Drivers of vehicles which do not comply with minimum emissions standards are charged a daily fee of £12.50 for entering the Ulez area. The mayor’s office estimated that 135,000 vehicles would be affected on an average day if the boundaries are widened as planned.
Whether or not a vehicle is liable for the charge depends on how much nitrogen dioxide (NO2) it emits. NO2 damages lungs and can exacerbate existing conditions such as asthma and lung and heart disease.
