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

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment he has made of the (a) adequacy and (b) effectiveness of national publicity of Clean Air Zones to all road users, including the (i) location and (ii) applicable time periods of those Zones.

We believe that local authorities are best placed to deliver communications on their local Clean Air Zones (CAZ). To support the local authorities with the communication of their local air quality plans, in this financial year, we have allocated £1.5m for their regional marketing campaigns.

We commissioned evaluations of the communications campaigns which showed that they were effective in raising and supporting awareness of the CAZ, driving people to the vehicle checker which provides further details of the individual CAZs.
