English: Thank you. In relation to the 50 mph sites, I think it's fair to say the evidence is mixed. In relation to the Wrexham one, what I said was I don't think people understand why there is a 50 mph site imposed. They think it's because of traffic calming or reducing speed and they wonder why the police aren't enforcing it. I didn't say the police would be enforcing it in relation to carbon emissions. So, what I have said is I would like to continue with the 50 mph sites, the five of them, but there must be signage explaining exactly what the reduction is for because I don't think people understand that. So, certainly the one in Wrexham, which I know the best because it's in my constituency, just says, 'Emissions reduction'. It's just a little sign that says, 'Emissions reduction', which people clearly don't understand. So, I don't think people have been adhering to it because I think there has been a little bit of confusion as to what it's for and because if they think it's because of speed and it's not being enforced, then they don't stick to the 50 mph. Certainly, the evidence that I've seen from across the five sites is mixed, but I think if we have signage saying very clearly that poor air quality kills - and I think that you have to sometimes shock people - then people will adhere to the reduction more willingly. I think hindsight's a wonderful thing. Certainly, I remember when we were all told to get diesel cars. What I would like to see now is a move to electric vehicles more. Unfortunately, we need the infrastructure to go with it, and we gave £2 million to put more electric vehicle charging points, for instance, in across Wales because we need to make sure that people can get about without the worry of running out of charge and then not being able to find a charging point. I think we need to do a significant amount of work to make sure that we have the infrastructure in place.
Welsh: Diolch. O ran y parthau 50 milltir yr awr, rwy'n credu ei bod hi'n deg i ddweud bod y dystiolaeth yn gymysg. O ran yr un yn Wrecsam, yr hyn a ddywedais i oedd nad oeddwn i o'r farn bod pobl yn deall pam mae'r parth 50 milltir yr awr wedi ei orfodi yno. Maen nhw'n meddwl bod hyn i dawelu traffig neu i leihau cyflymder ac maen nhw'n gofyn pam nad yw'r heddlu'n ei orfodi. Wnes i ddim dweud y byddai'r heddlu'n ei orfodi o ran allyriadau carbon. Felly, yr hyn yr wyf i wedi ei ddweud yw y byddwn i'n hoffi parhau â'r safleoedd 50 milltir yr awr, y pump ohonyn nhw, ond bod yn rhaid cael arwyddion yn egluro'r union reswm am y gostyngiad am nad wyf i'n credu bod pobl yn deall hynny. Felly, yn sicr yr un yn Wrecsam, rwy'n gwybod am hwnnw'n well am ei fod yn fy etholaeth i, mae hwnnw'n dweud 'Lleihau allyriadau'. Dim ond arwydd bach sy'n dweud, 'Lleihau allyriadau', nad yw'n ddealladwy i bobl, yn amlwg. Felly, rwyf i'n credu nad yw pobl wedi bod yn cadw ato oherwydd rwy'n credu bod ychydig o ddryswch ynglŷn â'r rheswm amdano ac oherwydd os ydyn nhw'n meddwl bod hyn oherwydd cyflymder ac nad yw'n cael ei orfodi, yna ni fyddan nhw'n cadw at 50 milltir yr awr. Yn bendant, mae'r dystiolaeth yr wyf i wedi ei chael o'r pum safle yn gymysg, ond rwy'n credu pe byddai gennym ni arwyddion sy'n dweud yn glir iawn bod ansawdd aer gwael yn lladd - a chredaf ei bod yn rhaid i chi roi sioc i bobl weithiau - bydd pobl yn fwy parod i gadw at y gostyngiad. Peth hawdd iawn yw bod yn ddoeth wedi'r digwydd. Yn sicr, rwy'n cofio'n iawn pan oedden nhw'n dweud wrthym ni i gyd am gael ceir diesel. Yr hyn yr hoffwn i ei weld nawr yw mwy o symudiad tuag at gerbydau trydan. Yn anffodus, mae angen i ni gael y seilwaith i gyd-fynd â hyn, ac rydym ni wedi rhoi £2 filiwn i gael mwy o leoedd gwefru cerbydau trydan, er enghraifft, ledled Cymru gan fod angen i ni sicrhau bod pobl yn gallu mynd o gwmpas heb boeni am wagio'r batri ac wedyn heb fod yn gallu dod o hyd i bwynt gwefru. Rwy'n credu bod angen gwneud llawer iawn o waith i sicrhau bod y seilwaith ar gael.
