English: Can I thank Jane Hutt for all those questions? Many of these debates began during the years in which she exercised the responsibilities as finance Minister here in the Assembly, and I know how familiar she will be with them. I can give her an assurance that I have discussed all four tax proposals with the Chief Secretary to the Treasury, particularly in relation to the social care tax, to get doors open for us to discuss this idea with other parts of Whitehall, and in relation to the plastics tax to make sure that Wales is as much involved as we can be in the call for evidence that the UK Government is taking forward. The fact that we have offered to help make sure that that call for evidence is widely publicised in Wales will, I hope, open doors to her constituents and others to take part in it. She is absolutely right when she points to the fact that the public are ahead of this debate and are already taking actions in their own lives to address the detriment that plastics can have on the environment that we all have to enjoy. As far as any mapping or pilots are concerned, I can say this to her, that in a sample survey of land identified in local development plans for housing development purposes, 25 per cent of all those sites turned out to have no activity taking place on them at all. It is a small survey, and it's a sample survey, so I wouldn't want to place enormous weight on it, but it's indicative, I think, of the scale of the issue. In another development, the Welsh Government recently announced a project using £32 million-worth of financial transaction capital and £8 million of conventional capital on a stalled sites fund to bring forward sites so that they can be used for proper public purposes. There are over 400 sites in Wales identified as potential beneficiaries from that fund.
Welsh: A gaf i ddiolch i Jane Hutt am y cwestiynau hynny i gyd? Dechreuodd llawer o'r trafodaethau hyn pan oedd ganddi hi'r cyfrifoldeb fel Gweinidog cyllid yma yn y Cynulliad, ac rwy'n gwybod pa mor gyfarwydd fydd hi â nhw. Gallaf ei sicrhau fy mod wedi trafod pob un o'r pedwar cynnig treth â Phrif Ysgrifennydd y Trysorlys, yn enwedig o ran y dreth gofal cymdeithasol, i sicrhau bod drysau'n agor i ni gael trafod y syniad hwn â rhannau eraill o Whitehall, ac o ran y dreth plastigau, i wneud yn siŵr bod Cymru yn ymgysylltu cymaint ag y gallwn yn yr alwad am dystiolaeth y mae Llywodraeth y DU yn ei gyflwyno. Bydd y ffaith ein bod wedi cynnig helpu i wneud yn siŵr bod yr alwad honno am dystiolaeth yn cael cyhoeddusrwydd eang yng Nghymru, gobeithio, yn agor drysau i'w hetholwyr ac eraill i gymryd rhan ynddi. Mae hi yn llygad ei lle wrth dynnu sylw at y ffaith bod y cyhoedd ar y blaen o ran y ddadl hon, a'u bod eisoes yn cymryd camau yn eu bywydau eu hunain i fynd i'r afael â'r niwed y gall plastigau ei wneud ar yr amgylchedd sydd i bawb ei fwynhau. O ran unrhyw fapio neu gynlluniau peilot, gallaf ddweud hyn, mewn arolwg sampl o dir a nodir mewn cynlluniau datblygu lleol at ddibenion datblygu tai, daeth i'r amlwg nad oes unrhyw weithgarwch o gwbl yn digwydd ar 25 y cant o'r holl safleoedd hynny. Arolwg bach ydyw, ac mae'n arolwg sampl, felly ni fyddwn i eisiau rhoi gormodedd o bwysau arno, ond mae'n arwydd, rwy'n credu, o raddfa'r mater hwn. Datblygiad arall i'w nodi: cyhoeddodd Llywodraeth Cymru yn ddiweddar brosiect yn defnyddio cyfalaf trafodion ariannol gwerth £32 miliwn ac £8 miliwn o gyfalaf confensiynol ar gronfa o safleoedd sydd wedi arafu, i ddwyn safleoedd yn eu blaenau fel y gellir eu defnyddio at ddibenion cyhoeddus priodol. Mae dros 400 o safleoedd yng Nghymru wedi'u nodi a allai elwa ar y gronfa honno.
