Thank you, Deputy Presiding Officer. I am pleased that we seem to be moving in the right direction, though we have been slow off the mark. Nearly two years ago we were looking at the Government's outline programme for this Assembly, and I can't remember if there was no reference to air quality or it was just cursory, but they certainly weren't the sort of commitments that we've just heard—that we need to be a leader in developing a clean air environment. So, I do welcome that, but Scotland seemed to be a fair bit ahead of us as they have four clean air zones to be established this year. In fairness, there has been some confusion over the implementation of clean air zones and where the actual power lies, but, now we have clarification to act, I think the Welsh Government needs to move very quickly and, in my view, we need clean air zones in Cardiff, Swansea and Newport, and possibly in other areas.

We need to really be aware of the advantages that these integrated policies to improve air quality can have. You may be aware that, in Berlin, their clean air zone, which was launched in 2008 and expanded in 2010, led to emission reductions that were up to 50 per cent lower than the predicted trend. That does show what we can achieve. So, energy—if that's not an inappropriate imperative at the moment to urge on you—is appropriate to improve our air quality.

Can I say secondly, on the launch of the new Air Quality in Wales website, that that is something that can involve the public and ensure that you get that wider participation? One area Welsh Conservatives have been very concerned about is in the collection of data in the immediate vicinities of our schools and nurseries in Wales. This is an area perhaps we could now look at. If I jump to the air quality monitoring centre for Wales, it seems to me that this can be linked very much to the website, and also the centre could be a key educational source for schools to engage children in initiatives to improve air quality. A project along these lines has been going on in Oxford and has led to some really interesting and encouraging results. And we need that sort of imagination.

On road congestion and restricting the most polluting vehicles, I think we need to progress in this area, but, in our urban areas, obviously, we are to some extent restricted by history and we do not, largely speaking, have public transport systems and a culture of walking more extensively now, and that needs to be changed over time. In this transition, we need to take people with us because some people, at the moment, unfortunately, see no alternative to the car. So, I think public transport systems operating effectively and appropriate traffic restrictions, clean air zones—all these need to be integrated into an approach that sees an improvement in public transport and other active travel networks such as city-centre streets as pedestrian-only areas. We can open up the historic centres of our cities to the people again and not have them restricted, as they often are, by excessive motor transport. So, there are some real possibilities here that would make the environment much, much better.

In terms of another consultation—. There are lots of consultations, and I do hope they will progress speedily. Again, my phrasing is way out. But in terms of reducing nitrogen dioxide concentrations, the impact on ambient air quality here is enormous, and whilst we don't have a compliant plan at the moment, and you want to bring one in by 31 July—obviously it's when that plan gets implemented that it's really going to have an impact on people—I am pleased to see that certain roads are targeted, like the A470 between Upper Boat and Pontypridd in my region, which is the most heavily polluted road in Wales at the moment. But, again, that feeds in, I think, to the points I made about the wider public transport infrastructure problem. So, we've got a lot to do, but I do, insofar as it has been indicated today, welcome the modest progress and I hope that now we see implementation soon.
