English: Thank you very much for that question. I too have one of these speed limits in my own constituency, so I'm very well aware - I've had exactly the same. The cameras have just gone live, and as you say, there's much more talk about them. I think the monitoring report that the Minister for Economy and Transport published on 7 October did confirm that, since the introduction of the 50 mph speed limit in June 2018, levels on the A470 between Upper Boat and the Bridge Street interchange have reduced, but of course they still remain above the EU directive limit of 40 μg/cu m. So it's too early to make any firm conclusions, and further monitoring is obviously being undertaken, but we were very reassured that across all of the five sites, we have seen a reduction. I think that now speed cameras are in place, that will encourage people again to adhere to those speed limits, which perhaps hasn't been the case over the last year, since the limits were first introduced. Unfortunately, due to bad weather, the signs - because I thought it was very important we communicated much more clearly why we were putting those speed limits in place. In the other four sites, they've all had the signage installed now, but unfortunately on the A470 they haven't been able to do that. But we are looking - certainly the Minister's officials are looking to do that as a matter of urgency. [ Interruption. ] That's good to hear. It's so that people understand why we're doing it, because I think initially there was some confusion over the need for that 50 mph zone. I think the point that you make around thinking about where to site jobs, particularly public sector jobs, shows why it has to be across government, why it's not just the responsibility of the Minister for economy, or myself as Minister with responsibility for the environment. It has to be cross-government, and that's why all Ministers have to look at their policies to make sure we're doing all that we can around air pollution.
Welsh: Diolch yn fawr i chi am y cwestiwn hwnnw. Mae gennyf finnau un o'r terfynau cyflymder hyn yn fy etholaeth hefyd, felly rwy'n ymwybodol iawn - rwyf wedi cael yr un peth yn union yn digwydd i mi. Mae'r camerâu newydd fynd yn weithredol, ac fel y dywedwch, mae llawer mwy o siarad amdanynt. Credaf fod yr adroddiad monitro a gyhoeddwyd gan Weinidog yr Economi a Thrafnidiaeth ar 7 Hydref wedi cadarnhau, ers cyflwyno'r terfyn cyflymder 50 mya ym mis Mehefin 2018, fod y lefelau ar yr A470 rhwng Glan-bad a chyfnewidfa Bridge Street wedi gostwng, ond wrth gwrs, maent yn parhau i fod yn uwch na therfyn cyfarwyddeb yr UE o 40 μg/cu m. Felly mae'n rhy gynnar i ffurfio unrhyw gasgliadau cadarn, ac mae gwaith monitro pellach yn cael ei wneud wrth gwrs, ond roedd yn galonogol iawn gweld gostyngiad ar draws pob un o'r pum safle. Gan fod camerâu cyflymder ar waith bellach, credaf y bydd hynny'n annog pobl i gadw at y terfynau cyflymder hynny eto, rhywbeth nad yw wedi digwydd dros y flwyddyn ddiwethaf o bosibl, ers i'r terfynau gael eu cyflwyno gyntaf. Yn anffodus, oherwydd tywydd gwael, mae'r arwyddion - oherwydd roeddwn yn credu ei bod yn bwysig iawn ein bod yn cyfleu, yn llawer mwy eglur, pam roeddem yn rhoi'r terfynau cyflymder hynny ar waith. Yn y pedwar safle arall, mae'r arwyddion i gyd wedi'u gosod erbyn hyn, ond yn anffodus nid ydynt wedi gallu gwneud hynny ar yr A470. Ond rydym yn edrych - yn sicr mae swyddogion y Gweinidog yn bwriadu gwneud hynny fel mater o frys. [ Torri ar draws. ] Mae'n dda clywed hynny. Mae'n golygu bod pobl yn deall pam ein bod yn gwneud hyn, oherwydd rwy'n credu bod rhywfaint o ddryswch ynghylch yr angen am y parth 50 mya ar y cychwyn. Credaf fod y pwynt a wnewch ynglŷn â meddwl ble i leoli swyddi, yn enwedig swyddi sector cyhoeddus, yn dangos pam y mae'n rhaid iddo ddigwydd ar draws y Llywodraeth, pam nad yw ond yn gyfrifoldeb i Weinidog yr economi, neu fi fel y Gweinidog sydd â chyfrifoldeb dros yr amgylchedd. Mae'n rhaid iddo fod yn drawslywodraethol, a dyna pam fod angen i bob Gweinidog edrych ar eu polisïau i wneud yn siŵr ein bod yn gwneud popeth yn ein gallu mewn perthynas â llygredd aer.
