English: No, no. Innovation tax credits taking over from where we are with the research and development tax credits, to make good the shortfall we have in Wales in terms of innovation and R&D; a workforce development levy, which would, in effect, take over from the apprenticeship levy - and we know some of the difficulties with that, and we would take control; and the other ones laid out, but let's throw a couple of other ones in here. The social care one has already been mentioned. I think that is worthy of looking at, but it is a hefty one to actually test the machinery on. The vacant land levy, I think, is fascinating because we all know the amount of not only land backed by investor communities, but derelict properties on that land that are left as an eyesore. What about tax relief for democratic engagement? The point that was made in actually getting more people to engage in the democratic process: maybe we should be incentivising them to do it by some sort of tax relief for democratic engagement if they participate in elections. What about a windfarm windfall? Because some of the windfarms that were set up 20 or 25 years ago give, frankly, diddly-squat to the communities that they're in. Maybe you should be looking at those for those older historic windfarms that are reaping the dividends now. What about an out-of-town development levy to promote high-street regeneration and subsidise free parking? What about a minerals and opencast levy to fund the remediation of those opencast and quarries? What about a flood alleviation or climate change adaptation levy on larger land owners to promote investment in water catchment management schemes and flood prevention? Now, I have to say, those are not all - . I said about unintended consequences, I talked about avoiding regressive taxes, avoiding non-devolved issues; I say that none of those - . Mark, just in case you're going to put them out in a press release, none of those are firm proposals. I'd want them all checked through, first of all. But we should be looking for the right one to test this, so that we end up with a tax for the common good. There is a reason to do taxes, and if they change behaviour or they actually make better the environment we live in - or the standard of living that we have - then that's a good reason for a tax.
Welsh: Na, na. Credydau treth arloesi'n cymryd drosodd o ble yr ydym â'r credydau treth ymchwil a datblygu, i wneud iawn am y diffyg sydd gennym yng Nghymru o ran arloesi ac ymchwil a datblygu; ardoll datblygu'r gweithlu, a fyddai, i bob pwrpas, yn cymryd lle'r ardoll prentisiaethau - a gwyddom am rai o'r anawsterau gyda hynny, a byddem yn cymryd rheolaeth; a'r rhai eraill a nodwyd, ond gadewch inni ychwanegu ychydig o rai eraill yma. Mae'r un gofal cymdeithasol eisoes wedi ei grybwyll. Rwy'n credu ei fod yn werth edrych arno, ond mae'n un trwm i'w ddefnyddio i brofi'r system. Mae'r ardoll tir gwag, rwy'n meddwl, yn hynod ddiddorol oherwydd rydym i gyd yn gwybod nid yn unig faint o dir sydd wedi'i gefnogi gan gymunedau buddsoddwyr, ond faint o eiddo adfeiliedig ar y tir hwnnw sy'n cael eu gadael fel dolur llygad. Beth am ryddhad treth am ymgysylltiad democrataidd? Y pwynt a wnaethpwyd o ran sicrhau bod mwy o bobl yn cymryd rhan yn y broses ddemocrataidd: efallai y dylem fod yn eu cymell i wneud hynny drwy ryw fath o ryddhad treth am ymgysylltiad democrataidd os ydynt yn cymryd rhan mewn etholiadau. Beth am arian annisgwyl i ffermydd gwynt? Oherwydd nid yw rhai o'r ffermydd gwynt a sefydlwyd 20 neu 25 mlynedd yn ôl yn rhoi, a dweud y gwir, affliw o ddim i'r cymunedau y maent ynddynt. Efallai y dylech fod yn edrych ar y rheini ar gyfer y ffermydd gwynt hanesyddol hŷn hynny sy'n dwyn ffrwyth erbyn hyn. Beth am ardoll datblygu y tu allan i'r dref i hyrwyddo adfywio strydoedd mawr a rhoi cymhorthdal ar gyfer parcio am ddim? Beth am ardoll mwynau a glo brig i ariannu adfer safleoedd glo brig a chwareli? Beth am ardoll lliniaru llifogydd neu addasu i newid yn yr hinsawdd ar dirfeddianwyr mwy i hyrwyddo buddsoddiad mewn cynlluniau rheoli dalgylchoedd dŵr ac atal llifogydd? Nawr, rhaid imi ddweud, nid dyna'r holl - . Soniais am ganlyniadau anfwriadol, soniais am osgoi trethi atchweliadol, ac osgoi materion sydd heb eu datganoli; rwy'n dweud nad yw dim un o'r rheini - . Mark, rhag ofn eich bod yn mynd i'w rhyddhau mewn datganiad i'r wasg, nid yw dim un o'r rheini'n gynnig cadarn. Byddwn eisiau iddynt i gyd gael eu gwirio, yn gyntaf oll. Ond dylem fod yn chwilio am yr un iawn i brofi hyn, fel y cawn yn y diwedd dreth sydd er lles pawb. Mae yna reswm i wneud trethi, ac os ydynt yn newid ymddygiad neu wir yn gwella'r amgylchedd yr ydym yn byw ynddo - neu'r safon byw sydd gennym - mae hynny'n rheswm da dros dreth.
