English: Thank you, David Melding, and, obviously, my officials particularly have worked very closely with Healthy Air Cymru, and I was very pleased they welcomed the plan this morning and I'll certainly continue to work with them. I just mentioned, in my answer to Jayne Bryant, I think it's really important that we work with our stakeholders going forward. The First Minister's manifesto commitment was to improve air quality through the development of a clean air Act for Wales. It would absolutely provide a formal mechanism, and I am committed to bringing forward a White Paper before the end of this term. But, as I say, we do have access to a wide range of levers to take forward action now to improve air quality, and local authorities currently have powers, for instance, to introduce low emission zones and clean air zones, either charging or non-charging. They do, again, have the powers to introduce fines for engine idling that you referred to as being an issue. But I do think we need to consider how we can enhance these powers through a clean air Act, and that is absolutely the intention of this Government. Talking about schools, when I mentioned to Andrew R.T. Davies that I'd recently been in Madrid for COP25, which is still ongoing, one of the things I saw in Madrid was living walls. So, incredible, really high walls just covered in greenery and with irrigation in them, and you just wonder why we don't have more of those in this country, and that's certainly something I'd be very keen to take forward. And you talked about the schools monitoring their air quality. I think I mentioned to Jayne Bryant that they need to take a risk-based approach in siting their monitors. They know the local population and the local area the best and they need to make sure they look at the guidance that we've given around schools and active travel routes.
Welsh: Diolch, David Melding ac, yn amlwg, mae fy swyddogion i, yn arbennig, wedi bod yn gweithio'n agos iawn gydag Awyr Iach Cymru. Roeddwn i'n falch iawn eu bod nhw'n croesawu'r cynllun y bore yma a byddaf i'n sicr o barhau i weithio gyda nhw. Rwyf newydd ddweud, yn fy ateb i Jayne Bryant, fy mod i'n credu ei bod yn bwysig iawn ein bod ni'n gweithio gyda'n rhanddeiliaid wrth symud ymlaen. Yr ymrwymiad ym maniffesto'r Prif Weinidog oedd gwella ansawdd aer drwy ddatblygu Deddf aer glân i Gymru. Fe fyddai hynny'n sicr yn darparu mecanwaith ffurfiol, ac rwyf wedi ymrwymo i gyflwyno Papur Gwyn cyn diwedd y tymor hwn. Ond fel y dywedais, mae ystod eang o ddulliau ar gael inni ar gyfer gweithredu nawr i wella ansawdd aer, ac ar hyn o bryd mae gan awdurdodau lleol bwerau, er enghraifft, i gyflwyno parthau allyriadau isel a pharthau aer glân, naill ai drwy godi tâl neu heb godi tâl. Mae ganddyn nhw, hefyd, y pwerau i gyflwyno dirwyon ar gyfer injans ceir yn troi'n ddiangen, y cyfeiriasoch ato fel problem. Ond rwy'n credu bod angen inni ystyried sut y gallwn ni rymuso'r pwerau hyn drwy Ddeddf aer glân, a dyna fwriad y Llywodraeth hon yn bendant. Wrth sôn am ysgolion, pan soniais wrth Andrew R.T. Davies fy mod i wedi bod ym Madrid ar gyfer y cyfarfod COP25 yn ddiweddar, sy'n dal i fynd rhagddo, un o'r pethau a welais i ym Madrid oedd waliau byw. Felly, mae yna waliau gwirioneddol uchel anhygoel wedi cael eu gorchuddio â gwyrddni ac yn cael eu dyfrhau o'r tu mewn. Tybed pam nad oes gennym ni fwy o waliau o'r fath yn y wlad hon, ac mae hynny'n sicr yn rhywbeth y byddwn i'n awyddus iawn i'w ddatblygu. Ac roeddech chi'n siarad am ysgolion yn monitro ansawdd eu haer nhw. Rwy'n credu imi sôn wrth Jayne Bryant fod angen iddyn nhw ddilyn dull sy'n seiliedig ar risg wrth leoli eu monitorau. Y nhw sy'n adnabod y boblogaeth leol a'r ardal leol orau ac mae angen iddyn nhw wneud yn siŵr eu bod yn edrych ar ein canllawiau ni ynglŷn ag ysgolion a llwybrau teithio llesol.
