The LEZ reduces harmful emissions of PM10 and NOx across London by targeting the most individually polluting types of vehicles. In this way it is possible to have a significant impact on air quality while minimising the number of people affected and the cost, size and complexity of the scheme.

Widening the scope of the LEZ to require all diesel vehicles, including cars, to meet the Euro IV for PM standard, either across London or in central London only, would result in considerable compliance costs for vehicle owners. It would also have significant social inclusion impacts and high set-up and operating costs for TfL.

To address car emissions further, my Transport Strategy and draft Air Quality Strategy contain a range of measures including the development of low emission vehicle infrastructure (electric vehicles), smarter travel schemes, funding and support for car clubs, and a range of policies for smoothing traffic flow.
