Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, how the national vehicle checking platform being prepared by the Joint Air Quality Unit will enable the public to obtain information about vehicles’ real world emissions; and whether there are plans to use that information (a) as the basis for stricter emission limits for Clean Air Zones in the future and (b) to set a path towards a zero emission road network.

To support charging clean air zones, we are developing an online tool for drivers to check if their vehicle would be subject to a charge for driving in areas where charging is necessary to achieve compliance with NO₂ limits in the shortest time possible. There are no plans at present to extend this service for other emission limits or to use this for wider air quality purposes.
