The Mayor of London, Sadiq Khan announced the introduction of the Central London Ultra Low Emission Zone (ULEZ). The ULEZ has the same boundaries as the existing congestion charge zone but applies 24 hours, all days of the year. There are also no exemptions for motorbikes and scooters. Older and diesel vehicles will pay a new £12.50-a-day charge, which must be paid on top of the existing congestion charge. Sadiq Khan also announced that 75% of all Transport for London buses, including all buses operating in the ULEZ zone, now “meet or exceed the emission standard”.
