We've not just published a strategy for cities; it's very important that we emphasise urban areas and you can look at the south Wales Valleys area as being, potentially, a more interconnected urban area. If you're looking at Swansea and then stretching across to Llanelli and beyond, it is very important. I accept that there is a danger you can suck too much into the core of these city regions, and that's something that certainly good planning must ensure that we avoid.

So, anyway, our policies cover the short, medium and long term and address four key themes of lifestyle, transport, housing and design. I should say that that detail on our housing policy will be fleshed out in a separate strategy document that we'll publish in the autumn. But, anyway, the areas that we've look at include parks and green spaces, internet connectivity, cycling and walking, electric vehicles, energy efficiency in housing, and increased tree coverage and green roofs. I was delighted that, in Cardiff University's sustainability strategy, they emphasise the need for greater biodiversity across their estate, not just in the green areas and their gardens but in green roofs. So, that's something that we want to see our universities leading in many respects.

As to the heart of the commitments that we have—as I said, there are 25—perhaps the core ones could be taken to be to make Cardiff the UK's first carbon neutral city. I do think that by marketing Cardiff in this way and leading the way, rather than waiting 10 years and then do what we have to do because of public pressure and what other cities are doing, we can really be ahead of the game and use it to project Cardiff's image as a forward-looking city. We want to pilot a city-wide single-use plastic ban in Wales and we're open to offers of where that should be. We want to ensure that all commercial developments over 1,000 sq m must have green roofing for at least 50 per cent of the total roof area of the development. A lot of cities around North America and Europe are now doing this and I point to Sheffield in the UK as a leader in this area. We want publicly owned urban brownfield sites to be provided at a discount to develop urban eco quarters. These would be housing developments with shared gardens that are high density, sustainable and provide for a mixture of tenures. I talked earlier about co-operatives, and this would be a key area for them, I think. We want to develop clean air zones in Newport, Swansea, Cardiff and Wrexham. And finally, can I just say that we aim to co-ordinate our urban policies so that more of Wales's busiest streets can become pedestrian zones?

So, that's our strategy. Can I just say that I think we've provided a very coherent vision of the way forward? And, therefore, I will not be supporting Plaid Cymru's amendment 2, but I will support amendment 3, which does touch upon a very important issue relating to urban strategy. We're happy to incorporate that as we find it constructive. So, I'm delighted to initiate this debate this afternoon, Llywydd, and I look forward for Member's contributions.
