The Member's questions involve a number of points of policy, which it would be inappropriate for me to comment on specifically, but in relation to how this was dealt with in the court action, which may answer part of her question, because of the Welsh Government's acceptance that the 2017 plan did not comply with its duties, it made that representation in court, and so the discussions between ClientEarth and the Government relate to the terms of the consent Order, which embodies the Welsh Government's representations to the court. It told the court that those parts of the 2017 plan that fell within devolved competence were not compliant and that, at the time of the plan, it didn't have the available information to model exactly what steps would have the required outcomes.

The Government has said that a supplemental air quality plan will be consulted on very shortly, with a view to that being implemented or brought into effect later this year. There are some areas that are within Welsh Government control and some areas that are within the control of Cardiff city council and Caerphilly borough council, and there are discussions ongoing with those two authorities at the moment in relation to specific steps to tackle the problem.
