Intended to reduce most harmful vehicle exhaust pollutants by more than half, the zone will require vehicles travelling in central London to meet new emission standards 24 hours a day, seven days a week or pay a daily charge.

The ULEZ will require:

• Cars and small vans – Euro 6 for diesel engines (registered from 1 September 2015 so 5 years old or less in 2020) and Euro 4 for petrol engines (registered from 1 January 2006 so 14 years old or less in 2020).  Non-compliant vehicles could still drive in the zone but they will be required to pay a daily charge of £12.50;
• Large vans and minibuses – Euro 6 for diesel engines (registered from 1 September 2016 so 4 years old or less in 2020) and Euro 4 for petrol engines (registered from 1 January 2007 so 13 years old or less in 2020). Non-compliant vehicles will be required to pay a daily charge of £12.50;
• Heavy goods vehicles, buses and coaches – Euro VI (registered from 1 January 2014 so 6 years old or less in 2020 except TfL buses which are required to meet a higher standard).  Non- compliant vehicles will be required to pay a daily charge of £100;
• Motorcycles and similar vehicles – Euro 3 (registered from 1 July 2007 so 13 years old or less in 2020).  Non-compliant vehicles will be required to pay a daily charge of £12.50.

Transport for London that it will continue to lobby the Office for Low Emission Vehicles (OLEV) for further funding from its £500m funding pot to support the uptake of zero emission capable vehicles and put in place supporting charging infrastructure.
