English: Is the Minister suggesting the devolution of APD as an alternative to the M4 relief road? I'm not sure it would be on the same scale in terms of impact on congestion. I wonder, though, could he clarify, because he's used this word 'varying APD', and I think Andrew R.T. Davies has, entirely understandably, considered that might reflect a change of policy from the previous First Minister saying 'reducing', since varying may mean either increasing or reducing. The Minister has also said that he wants to consider this decision in light of environmental impact assessments, and I've heard some people - at least from a sedentary position on the Plaid side - suggesting that APD might need to go up in order to reduce the climate change impact. Can I also just ask for clarity on the legal situation here? You said just now that the well-being of future generations Act requires these environmental impact assessments. If so, why wasn't this realised or at least spoken about previously? And why didn't he take the opportunity of the 2017 York - sorry, the York Aviation report was 2014, but the Northpoint study in 2017 that his Government commissioned, that looked into quite a lot of these issues around where traffic was going to go? Why didn't that also consider the environmental impact? You also mentioned just now that it could lead to an increase of up to 500,000 passengers from Cardiff Airport. The York Aviation report said it might reduce Bristol by a million, and even his own Northpoint report said it might reduce Bristol by 600,000. So, why that discrepancy?
Welsh: A yw'r Gweinidog yn awgrymu datganoli toll teithwyr awyr fel dewis amgen yn lle ffordd liniaru M4? Nid wyf yn siŵr y byddai ar yr un raddfa o ran yr effaith ar dagfeydd. Er hynny, tybed a allai egluro, oherwydd mae wedi defnyddio'r gair 'amrywio' toll teithwyr awyr, a chredaf fod Andrew R.T. Davies, yn gwbl ddealladwy, wedi ystyried y gallai hynny ddynodi newid polisi o'r Prif Weinidog blaenorol yn dweud 'lleihau', gan y gallai amrywio olygu naill ai gynyddu neu leihau. Mae'r Gweinidog hefyd wedi dweud ei fod am ystyried y penderfyniad hwn yng ngoleuni asesiadau o effaith amgylcheddol, ac rwyf wedi clywed rhai pobl - o'u seddau ar ochr Plaid Cymru o leiaf - yn awgrymu y gallai fod angen i'r doll teithwyr awyr godi er mwyn lleihau'r effaith ar newid hinsawdd. A gaf fi hefyd ofyn am eglurder ar y sefyllfa gyfreithiol yma? Fe ddywedoch chi yn awr fod Deddf llesiant cenedlaethau'r dyfodol yn ei gwneud yn ofynnol i'r asesiadau hyn o'r effaith amgylcheddol gael eu cynnal. Os felly, pam na sylweddolwyd hynny neu o leiaf, pam na siaradwyd am hynny'n flaenorol? A pham na fanteisiodd ar gyfle adroddiad York Aviation 2017 - mae'n ddrwg gennyf, yn 2014 y cafwyd adroddiad York Aviation, ond astudiaeth Northpoint yn 2017 a gomisiynwyd gan ei Lywodraeth ef, ac a edrychodd ar gryn dipyn o'r materion hyn yn ymwneud â lle roedd traffig yn mynd i fynd? Pam na wnaeth hwnnw ystyried yr effaith amgylcheddol hefyd? Fe sonioch chi hefyd yn awr y gallai arwain at gynnydd o hyd at 500,000 o deithwyr o Faes Awyr Caerdydd. Dywedodd adroddiad York Aviation y gallai olygu miliwn yn llai o Fryste, ac roedd hyd yn oed ei adroddiad Northpoint ei hun yn dweud y gallai arwain at 600,000 yn llai o Fryste. Felly, pam yr anghysondeb hwnnw?
