The Mayor of London has launched a consultation on proposals to levy an emissions surcharge (ES) on the most polluting vehicles in the capital next year.

The ES will be an additional daily £10 supplement to the Congestion Charge payable by owners of older, more polluting, vehicles that drive in the Congestion Charging zone during charging hours. It will cover older diesel and petrol vehicles that do not meet the Euro 4/IV emissions standard for NOx and PM emissions. Pre-Euro 4/IV vehicles are generally those registered in 2005 and older.
