English: Like many others, I thoroughly welcome this debate. I welcome the debate because it's given us freedom, as an Assembly, to free-range a little bit and to say, 'Well, we're not afraid of throwing some of these things out into the open,' in a way, I have to say, that presaged this with the tax for good. There's the answer, Mark, that you were looking for. It isn't a tax just for testing it to see if the circuits run properly and the lights come on; it's actually the tax is for good, and I think part of this debate is to throw some of those ideas forward as to what it might be, and it could well be the model that Simon has just said there now. We know what good the plastic bag tax in Wales did, and the massive impact it had on recycling rates and reducing the amount of plastic bags that were going into the waste in the natural environment and so on. So, it might well be a logical extension of that, but there might be other ones to do with social care. That tax is for good is the issue, but it's right that we do test the machinery. I think the Minister is absolutely right, and this is part of our stepping up to the mark here, to encourage the Minister, in some ways, to say, 'Do do this, but pick the right one.' I think he's right to do it with care, to take this forward with consultation, in order that we do test some of the ideas of what would be the best service to the public good. I would say in doing that, however, we do need to guard against certain things. One is unintended consequences, and within that, by the way, even though I'm an advocate of environmental taxes and levies, we have to be cautious in the way that we design them, to make sure that there aren't unintended consequences. So, if, for example, Simon's idea there, and one that's been advocated by many environmental groups, were one that came into play in a few months' time and it was the one that was taken forward to test the machinery, let's also make sure it doesn't have any unintended consequences. Secondly, I would say, let's make sure - not least in times when we know, as always, people are finding it tough - that there is nothing regressive about any of the proposals we bring forward, and ideally they would be progressive rather than regressive. And not only on individuals but also on businesses, that that cost of complying with any new taxation is not unduly onerous. It will have an impact; you can't avoid that with a tax, if it impacts on a business, but that it's not unduly onerous - that it is within what we would consider proportionate. Finally, of course, as has been laid out not only today, but also in the Bevan Foundation paper, all those aspects of: is it within our devolved competence; does it deal with cross-border issues; does it deal with issues of tax avoidance, and so on? And I would say, in addition to the proposals that are within here, let's throw some in the mix as some suggestions. Within here it talks about a tourism levy. I have personally some concerns about that and the unintended consequences to do with the reputation of the country and so on. It was looked at some time for the south-west of England. A huge, huge dump of tourists into that area of the country through the summer months and so on, of course you could put a tourism levy, but if it was the only place in the country that had a tourism levy within the UK, well the impact there on reputation and profile of that as a tourism sector is quite interesting, but there are some advantages to it.

Welsh: Fel llawer o bobl eraill, rwy'n croesawu'r ddadl hon yn gynnes. Rwy'n croesawu'r ddadl, oherwydd mae wedi rhoi rhyddid inni, fel Cynulliad, i grwydro ychydig a dweud, 'Wel, dydyn ni ddim yn ofni taflu rhai o'r pethau hyn allan i'r agored,' mewn ffordd, rhaid imi ddweud, sydd wedi darogan hyn gyda'r dreth ar gyfer da. Dyna'r ateb, Mark, yr oeddech yn chwilio amdano. Nid dim ond treth i brofi i weld a yw'r cylchedau'n rhedeg yn iawn a'r goleuadau'n cynnau yw hon; mae'n dreth go iawn ar gyfer da, ac rwy'n meddwl mai rhan o'r ddadl hon yw cyflwyno rhai o'r syniadau hynny ynglŷn â'r hyn y gallai fod, ac mae'n bosibl iawn y bydd y model y mae Simon newydd ei ddweud yn y fan honno nawr. Rydym yn gwybod bod y dreth ar fagiau plastig yng Nghymru wedi gwneud lles, ac wedi cael effaith aruthrol ar gyfraddau ailgylchu a lleihau nifer y bagiau plastig a oedd yn mynd i mewn i'r gwastraff yn yr amgylchedd naturiol ac yn y blaen. Felly, mae'n ddigon posibl ei fod yn estyniad rhesymegol o hynny, ond gallai fod rhai eraill sy'n ymwneud â gofal cymdeithasol. Y pwynt yw ei bod yn dreth er da, ond mae'n iawn ein bod yn profi'r system. Rwy'n meddwl bod y Gweinidog yn llygad ei le, ac rydym yn gwneud hyn wrth gamu i fyny at y marc yma, i annog y Gweinidog, mewn rhai ffyrdd, i ddweud, 'Gwnewch hyn, ond dewiswch yr un iawn.' Rwy'n meddwl ei fod yn iawn i wneud hynny gyda gofal, i ymgynghori wrth fwrw ymlaen â hyn, er mwyn inni brofi rhai o'r syniadau ynglŷn â'r hyn a fyddai orau i fudd y cyhoedd. Byddwn yn dweud wrth wneud hynny, fodd bynnag, bod angen inni warchod rhag rhai pethau. Un yw canlyniadau anfwriadol, ac o fewn hynny, gyda llaw, er fy mod o blaid trethi ac ardollau amgylcheddol, mae'n rhaid inni eu cynllunio mewn ffordd ofalus, er mwyn sicrhau nad oes canlyniadau anfwriadol. Felly, pe bai, er enghraifft, syniad Simon yno, ac un sydd wedi cael ei argymell gan lawer o grwpiau amgylcheddol, yn un a fyddai'n berthnasol ymhen ychydig fisoedd ac mai hwnnw oedd yr un y byddem yn ei ddefnyddio i brofi'r system, gadewch inni hefyd wneud yn siŵr nad yw'n creu goblygiadau anfwriadol. Yn ail, byddwn yn dweud, gadewch inni wneud yn siŵr - yn enwedig mewn cyfnod pan fyddwn yn gwybod, fel bob amser, bod pobl yn ei chael hi'n anodd - nad oes dim byd atchweliadol am unrhyw un o'r cynigion yr ydym yn eu cyflwyno, ac yn ddelfrydol, byddent yn flaengar yn hytrach nag atchweliadol. Ac nid dim ond i unigolion ond hefyd i fusnesau, nad yw cost cydymffurfio ag unrhyw drethi newydd yn rhy feichus. Bydd yn cael effaith; ni allwch osgoi hynny gyda threth, os yw'n effeithio ar fusnes, ond nad yw'n rhy feichus - ei bod o fewn yr hyn y byddem yn ei ystyried yn gymesur. Yn olaf, wrth gwrs, fel y nodwyd nid yn unig heddiw, ond hefyd ym mhapur y Sefydliad Bevan, yr holl agweddau hynny ar: a yw o fewn ein cymhwysedd datganoledig; a yw'n ymdrin â materion trawsffiniol; a yw'n ymdrin â materion o osgoi talu treth, ac yn y blaen? A byddwn yn dweud, yn ychwanegol at y cynigion sydd o fewn hwn, gadewch inni ychwanegu rhai at y cymysgedd fel awgrymiadau. O fewn hwn mae'n sôn am ardoll twristiaeth. Mae gen i yn bersonol rai pryderon ynghylch hynny a'r canlyniadau anfwriadol o ran enw da'r wlad ac yn y blaen. Bu de-orllewin Lloegr yn edrych arno am gyfnod. Tomen enfawr, enfawr o dwristiaid yn mynd i'r rhan honno o'r wlad dros fisoedd yr haf ac yn y blaen, wrth gwrs fe allech chi godi ardoll twristiaeth, ond os mai dyna'r unig le yn y wlad ag ardoll twristiaeth o fewn y Deyrnas Unedig, wel mae'r effaith yno ar enw da a phroffil yr ardal fel sector twristiaeth yn eithaf diddorol, ond mae rhai manteision iddo. Arloesi - [Torri ar draws.] Mae'n ddrwg gennyf.
