English: Thank you, John Griffiths, for those questions. I have asked officials, because I think you've asked me a couple of times around taxi fleets, and I have asked officials to look specifically at Calor Gas and to see where else in the world they are used to be able to inform that. Smoking in public places, no, it doesn't come within my remit, but, as I said, this is a matter for every member of the Government, so I'll ensure that the Minister for Health and Social Services hears your comments. For those of us who don't suffer with respiratory disease, smoke - certainly the change, and obviously Wales was the first country to ban smoking in enclosed places, and we now accept that as completely normal, whereas not that long ago when you went into a pub, for instance, smoking was allowed and the impact it must have had on so many of us - . In relation to schools, I think you raise a really important point and, also, around behavioural change. The primary school that you mention from your own constituency is clearly a good example of that. If we think how we started raising public awareness and behavioural change around recycling, for instance, and climate change, it's with young people, so I think this is an excellent example of the school run, for want of a better word. Certainly, we know that the school run has a significant contribution in relation to levels of air pollution and traffic congestion on our roads within many school catchment areas, and that's certainly during the term-time rush-hour, as you alluded to. I think there's also the potential, going back to that behavioural change that is needed, for schools to help educate both children and parents on the issues around air quality and help us explore potential solutions, such as car sharing and if there are no-idling policies also on and around school grounds. So, we do give statutory guidance to local authorities, because we do recognise that schools and active travel routes, amongst others, are sort of sensitive receptor locations.
Welsh: Diolch i John Griffiths, am y cwestiynau yna. Rwyf i wedi gofyn i swyddogion, am fy mod i'n credu i chi ofyn i mi sawl tro ynglŷn â thacsis, ac rwyf i wedi gofyn i swyddogion edrych yn benodol ar Nwy Calor ac edrych ym mhle arall yn y byd y maen nhw'n cael eu defnyddio i allu cael mwy o wybodaeth am hynny. Ysmygu mewn mannau cyhoeddus, nac ydi, nid yw hynny'n rhan o'm cylch gwaith i, ond, fel y dywedais i, mae hwn yn fater i bob aelod o'r Llywodraeth, ac felly fe fyddaf i'n sicrhau bod y Gweinidog Iechyd a Gwasanaethau Cymdeithasol yn clywed eich sylwadau chi. I'r rhai ohonom ni nad ydym ni'n dioddef o glefyd anadlol, mae mwg - y newid yn sicr, a Chymru, yn amlwg, oedd y wlad gyntaf i wahardd ysmygu mewn mannau caeedig, ac rydym ni'n derbyn bod hynny'n rhywbeth cwbl arferol erbyn hyn, ond heb fod mor bell yn ôl â hynny, pan fyddech chi'n mynd i dafarn, er enghraifft, roedd hawl i ysmygu a'r effaith yr oedd hynny siŵr o'i gael ar gynifer ohonom ni - . O ran ysgolion, credaf eich bod chi'n codi pwynt pwysig iawn, a hefyd ynghylch newid mewn ymddygiad. Mae'r ysgol gynradd yr ydych chi'n sôn amdani yn eich etholaeth eich hun yn amlwg yn enghraifft dda o hynny. Os ydym ni'n ystyried sut y dechreuasom ni godi ymwybyddiaeth y cyhoedd a newid ymddygiad o ran ailgylchu, er enghraifft, a'r newid yn yr hinsawdd, gyda phobl ifanc y digwyddodd hynny, felly, mae hon yn enghraifft wych, yn fy marn i, o ddanfon plant i'r ysgol, i ddefnyddio'r priod-ddull hwnnw. Yn sicr, rydym ni'n gwybod bod danfon plant i'r ysgol yn gwneud cyfraniad sylweddol at lefelau llygredd aer a thagfeydd traffig ar ein ffyrdd mewn llawer o ddalgylchoedd ysgolion, ac mae hynny'n sicr yn ystod yr oriau prysuraf yn ystod tymor yr ysgol, fel y gwnaethoch chi ei grybwyll. Credaf fod potensial hefyd, gan fynd yn ôl at y newid mewn ymddygiad sydd ei angen, i ysgolion helpu i ddysgu plant a rhieni am y materion sy'n ymwneud ag ansawdd aer a'n helpu ni i archwilio atebion posibl, fel rhannu ceir ac a oes unrhyw bolisïau hefyd o ran peidio â gadael i injans droi yn segur ar dir yr ysgol ac o'i amgylch. Felly, rydym ni yn rhoi canllawiau statudol i awdurdodau lleol, oherwydd rydym ni yn cydnabod bod ysgolion a llwybrau teithio llesol, ymhlith pethau eraill, yn lleoliadau derbynnydd sensitif, i ryw raddau.
