English: Thanks to the Minister for her statement today, and thanks for the commitment that you've outlined. As David Melding and Simon Thomas have indicated, we have had a bit of a battle to get to this point, but at least there are now some commitments from the Government. Now, we've had quite a few discussions here in the Chamber on this subject during this Assembly term, and, of course, we all want to see the Welsh Government and the Assembly do their utmost to improve air quality in Wales, which is a big problem in most of our built-up urban areas, the question being: what action will be effective in achieving that aim? Now, a lot of air pollution, I think we all recognise, emanates from roads. One of your proposals today is for temporary 50 mph speed limits on motorways and trunk roads. Just a minor point, but I'd like to point out that you cite the A470 between Upper Boat and Pontypridd as one of the proposed 50 mph zones. Well, from what I'm told by regular users of the route, it's already a 50 mph zone, and has been since roadworks were carried out there some months ago. So, I just wanted to pass that information on. But a more important point is that these motorways and trunk roads are the only roads that the Welsh Government manages. The vast majority of roads are under local authority control, and these are the roads with pedestrians on them; you don't get many pedestrians on motorways and major trunk roads. So, of course, what you are going to need to do going forward is have some meaningful interaction with the local councils about how they are dealing with the pollution coming from their roads, and I think this is what we've been discussing, to some extent, today, how you're going to achieve that. I think we need strong guidance from the Welsh Government in this area. I know that you're proposing an air quality fund, which is good, but you may need to accompany it with strong guidance to ensure that the necessary action is implemented effectively. How strongly will you be overseeing the air quality fund as the relevant Minister? You say that you want to create clean air zones and restrict admission to these zones by banning certain kinds of polluting vehicles, and I think this is in many ways a fairly obvious step, but, as you recognise yourself, there are going to be major difficulties with this - cultural difficulties as much as anything. To look at the issue more precisely, HGVs have been mentioned by a couple of people. So, one obvious thing is: why have we got HGVs going through residential areas? Should this be allowed? So, that maybe needs to be looked at. But we do have to look at possible repercussions of bringing in these clean air zones, because we have had scientific evidence recently relating to what's happened in London since the congestion zone was brought in 15 years ago. There is recent research that indicates that, in some ways, air quality has actually worsened in London. In particular, the diesel pollution has increased by 20 per cent. This is because of the increased traffic from diesel-powered buses and taxis. So, yes, you can look towards public transport, which you're citing here, but you need to look at what are the emissions coming from public transport, I guess is what I'm saying. So, how are you going to monitor the fleets of buses and the licensed taxis that operate through the 22 local authority areas in Wales? Because you're going to need to look at that and assess the pollution elements of that if you are encouraging public transport rather than private vehicle use into these areas. But you need to do all of that first, I think, and, once you've got those measures in place - and Simon Thomas has mentioned that extra legislation may be needed - then you've got the big task of the cultural change of persuading people who do drive when they could walk to actually get out of the vehicles and do so. But, of course, at the moment it's kind of a vicious circle, because you can't persuade people to get out of their vehicles and walk to places like the school because the roads are so polluted, why would they want to do that? So, you need to tackle this cycle at some point, so good luck with it and I'm interested to hear your answers. Thank you.
Welsh: Diolch i'r Gweinidog am ei datganiad heddiw, a diolch am yr ymrwymiad yr ydych chi wedi'i amlinellu. Fel y mae David Melding a Simon Thomas wedi nodi, rydym wedi cael cryn frwydr i gyrraedd y pwynt hwn, ond o leiaf bellach bod rhai ymrwymiadau gan y Llywodraeth. Nawr, rydym ni wedi cael trafodaethau pur helaeth yma yn y Siambr ar y pwnc hwn yn ystod tymor y Cynulliad hwn, ac, wrth gwrs, rydym ni i gyd eisiau gweld Llywodraeth Cymru a'r Cynulliad yn gwneud eu gorau glas i wella ansawdd aer yng Nghymru, sy'n broblem fawr yn y rhan fwyaf o'n hardaloedd adeiledig trefol, a'r cwestiwn yw: pa gamau fydd yn effeithiol o ran cyflawni'r nod hwnnw? Nawr, mae llawer o lygredd aer, rwy'n credu ein bod i gyd yn cydnabod, yn dod o ffyrdd. Mae un o'ch cynigion heddiw ar gyfer terfynau cyflymder 50 mya dros dro ar draffyrdd a chefnffyrdd. Dim ond mân bwynt, ond hoffwn nodi ichi enwi'r A470 rhwng Glan-bad a Phontypridd fel un o'r parthau 50 mya arfaethedig. Wel, o'r hyn y mae defnyddwyr rheolaidd o'r ffordd yn ei ddweud wrthyf, mae eisoes yn barth 50 mya, ac wedi bod ers i waith ffordd gael ei wneud yno rai misoedd yn ôl. Felly, roeddwn i eisiau cyfleu'r wybodaeth honno. Ond pwynt pwysicach yw mai'r traffyrdd a'r cefnffyrdd hyn yw'r unig ffyrdd y mae Llywodraeth Cymru yn eu rheoli. Mae'r rhan fwyaf o ffyrdd o dan reolaeth yr awdurdod lleol, ac mae'r rhain yn ffyrdd â cherddwyr arnynt; dydych chi ddim yn cael llawer o gerddwyr ar draffyrdd a chefnffyrdd mawr. Felly, wrth gwrs, yr hyn y mae angen ichi ei wneud wrth symud ymlaen yw cael rhywfaint o drafodaethau ystyrlon gyda chynghorau lleol ynghylch sut y maen nhw'n ymdrin â llygredd sy'n dod o'u ffyrdd, ac rwy'n credu mai dyma beth yr ydym ni wedi bod yn ei drafod, i ryw raddau, heddiw, sut yr ydych chi'n mynd i gyflawni hynny. Rwy'n credu bod angen arweiniad cryf arnom ni gan Lywodraeth Cymru yn y maes hwn. Rwy'n gwybod eich bod yn cynnig cronfa ansawdd aer, sy'n beth da, ond efallai y bydd angen ichi gynnwys canllawiau cadarn hefyd i sicrhau y cyflawnir y camau angenrheidiol yn effeithiol. Pa mor drylwyr fyddwch chi'n goruchwylio'r gronfa ansawdd aer fel y Gweinidog perthnasol? Rydych chi'n dweud yr hoffech chi greu parthau aer glân a chyfyngu ar fynediad i'r parthau hyn drwy wahardd mathau penodol o gerbydau sy'n llygru, ac rwy'n credu bod hwn yn gam eithaf amlwg mewn sawl ffordd, ond, fel yr ydych chi'n ei gydnabod eich hun, bydd yna anawsterau mawr â hyn - anawsterau diwylliannol cymaint ag unrhyw beth arall. I edrych ar y mater yn fwy manwl, mae sawl person wedi sôn am gerbydau nwyddau trwm. Felly, un peth amlwg yw: pam mae gennym ni gerbydau nwyddau trwm yn mynd drwy ardaloedd preswyl? A ddylid caniatáu hyn? Felly, efallai bod angen edrych ar hynny. Ond mae'n rhaid inni edrych ar sgil-effeithiau posib cyflwyno parthau aer glân, oherwydd cawsom dystiolaeth wyddonol ddiweddar ynghylch beth sydd wedi digwydd yn Llundain ers cyflwyno'r parth tagfeydd 15 mlynedd yn ôl. Mae gwaith ymchwil diweddar yn dangos, mewn rhai ffyrdd, bod ansawdd yr aer wedi gwaethygu yn Llundain, mewn gwirionedd. Yn benodol, mae llygredd diesel wedi cynyddu 20 y cant. Mae hyn oherwydd y cynnydd mewn traffig ar ffurf bysiau a thacsis sy'n cael eu pweru gan ddiesel. Felly, ie, gallwch edrych ar drafnidiaeth gyhoeddus, ac rydych yn ei nodi yn y fan yma, ond mae angen i chi edrych ar yr allyriadau sy'n dod o drafnidiaeth gyhoeddus, rwy'n credu mai dyna rwyf yn ei ddweud. Felly, sut byddwch chi'n monitro'r fflydoedd o fysiau a thacsis trwyddedig sy'n gweithredu drwy'r 22 ardal awdurdod lleol yng Nghymru? Oherwydd bydd angen i chi ystyried hynny ac asesu elfennau llygredd hynny os ydych chi'n annog trafnidiaeth gyhoeddus yn hytrach na defnyddio cerbydau preifat yn yr ardaloedd hyn. Ond mae angen ichi wneud hynny i gyd yn gyntaf, rwy'n credu, ac, unwaith y bydd gennych chi'r mesurau hynny ar waith - ac mae Simon Thomas wedi sôn am y ddeddfwriaeth ychwanegol y gallai fod ei hangen - yna mae gennych chi'r dasg fawr sef y newid diwylliannol hwnnw o ddwyn perswâd ar bobl sy'n gyrru pan gallen nhw gerdded i adael y cerbydau a gwneud hynny. Ond, wrth gwrs, ar hyn o bryd mae'n fath o gylch dieflig, oherwydd ni ellir dwyn perswâd ar bobl i adael eu cerbydau a cherdded i leoedd fel yr ysgol oherwydd bod y ffyrdd mor llygredig, pam fydden nhw eisiau gwneud hynny? Felly, mae angen ichi fynd i'r afael â'r cylch hwn ar ryw adeg, felly pob lwc ac mae gennyf ddiddordeb clywed eich atebion. Diolch.
