Question to the Department for Transport:

To ask Her Majesty’s Government what steps they are taking to define national standards for the creation of Low Emission Zones so that in future most vehicles are able to enter such zones.

Low Emission Zones (LEZs) are one of a number of measures that can help improve air quality, particularly in urban areas. Introducing LEZs is a decision for local authorities. Government has already provided guidance to local authorities on the design of LEZs, such as which vehicles should be covered and what emissions standards they should meet. The Department for Environment and Rural Affairs is currently working with a small number of local authorities who are examining the value of introducing such schemes.

Government is revising its air quality plans in relation to compliance with EU air quality standards. As part of this we are reviewing all feasible measures including the role of a national framework for LEZs. We will be consulting on revised air quality plans later in the year.
