I thank the noble Lord for his intervention. I was not saying that the local authority would have the information, but one would certainly expect it—particularly if it was a larger one—to be in contact with its local fleets of taxis and PHVs to understand the more general working practices. Each of these charging clean air zones will have been set up after local consultation. I expect that is one of the issues which the local fleets would have put into the consultation. We are not minded to provide national guidance at the moment, although obviously that may change in the future. For the time being, we believe that this should be a local decision and that it should be up to the local licensing authorities to come up with a reasonable solution for what works in their areas.
Security of data is obviously an important issue. Because of the powers in the Environment Act 1975, under which this is set up, the data can only be shared for the purpose of enforcing air quality measures. The Act limits the information that can be provided to the minimum necessary to identify the vehicle as a taxi or PHV and does not cover any personal data about the licence holder.
I believe I have covered pretty much everything.
