Thank you for that, Minister. It is crucially important that we get our policies to tackle air pollution right, given the effect on public health, respiratory conditions and other health conditions and, of course, the effect on our environment. And I think these problems are particularly acute in our more disadvantaged communities. So, the sooner we get practical policies in place that are going to make a real difference the better. And I think one example of that is the conversion of our taxi fleets to electric vehicles or certainly more environmentally friendly fuels. And I just wonder, within the money that's been made available, Minister, that you describe and the joint working between Welsh Government and local authorities, to what extent there's an assessment of the state of readiness of our local authorities to make these practical improvements and to work with them to make those positive differences as quickly as possible. Because it really is an urgent problem for our communities, and the sooner we get these practical improvements in place, the sooner public health and our environment will benefit.
