Well, indeed, it might be seen as an environmental issue, but it's as much a public health issue as anything else. In fact, the Assembly voted, in that debate that you just referred to, again for a Plaid Cymru amendment that called on the Welsh Government to treat air pollution as a public health issue as well as an environmental issue. You're not responsible for public health, I know, but across Government, clearly this needs to be joined up.

The Scottish Government has said that it wants to go in front of the Westminster Government in terms of phasing out new petrol and diesel by 2032. We have examples around Europe of cities phasing out diesel and petrol vehicles in a much shorter space of time than the Westminster Government's talked about. Is it not the time to at least consider pilot areas in Wales where diesel and petrol may actually be banned, either on specific days or specific times, in order to achieve some improvement in air quality in those areas that, to be frank, the current system just isn't tackling, and there are public health deaths quite directly as a result of that?
