English: You say in your statement, Minister, at least in the written version, that you've committed us to going even further, in achieving net zero emissions no later than 2050, yet you said in reply to Llyr Gruffydd that that was downgraded to an ambition, and we're legislating just for a 95 per cent cut, not for net zero. In what sense, then, are you committed to net zero instead of the 95 per cent reduction? Could you also - ? I know you weren't able to last week, and, if you can't now, could you perhaps give me a timetable when you might be able to do this - what is your policy in terms of international offsetting? Will it be allowed, and, if so, will there be a limit placed on it? I think your statement today is very timely, after the vote in the Commons - or not a vote in the Commons last night; it went through without even a vote - to change the 80 per cent reduction up to this far higher amount. I wonder about the cost of that. We have at least semi-official estimates of £50 billion or £70 billion a year, and I think it's much more sensible to focus on the annual cost than it is adding it up over an unknown period to get £1 trillion-plus scary numbers. But, if it is this £50 billion or £70 billion a year, then I welcome this process of carbon budget setting, of looking at what are the implications of this, because I think it's very easy for politicians to make great commitments for a long time in the future to synthesise a legacy for Theresa May or whatever other motivations there may be, but it's only when they come down to looking at what are the implications of this, what are the costs, what are the trade-offs, that, actually, you engage in real policy. And I think, with a 40 per cent or so cut in carbon dioxide emissions across the UK since 1990, we were leading the world in that and making really quite big strides in this area. I'm just concerned that, by lumping that up from 80 per cent to 95 per cent or 100 per cent without explaining how we're going to do that, there may again become a detachment between our ambitions and reality, or what our constituents would be prepared to accept in this area, given the trade-offs involved. You mentioned that coal is required at Port Talbot to make steel. How, then, do we decarbonise that process while retaining the industry? What is the intention in terms of gas boilers? To come anywhere near this, you're going to have to get rid of everyone's gas boilers. Are you looking to replace them with electric - currently three times the cost - or would you have hydrogen instead, and, if so, how on earth does one get to a situation where one cuts off the gas and puts in hydrogen at a point in time instead? How do you co-ordinate people's boilers for that? And could I ask you, finally, just to clarify a little further around this electricity production point? What's your assumption about what's going to happen with Aberthaw B that's so huge in terms of its implications in this area, and are you saying that as Welsh Government policy you would like to see a greater emphasis on autarchy and less in the way of exporting to England in electricity? What's wrong with exporting power to England? Is that a bad thing? If so, what do you intend to do about it?
Welsh: Rydych chi'n dweud yn eich datganiad, Gweinidog, yn y fersiwn ysgrifenedig o leiaf, eich bod wedi ymrwymo i fynd ymhellach hyd yn oed, o ran sicrhau dim allyriadau o gwbl a hynny erbyn 2050 fan bellaf. Eto i gyd, roeddech chi'n dweud wrth ateb Llyr Gruffydd fod hynny wedi cael ei israddio'n uchelgais, a'n bod ni'n deddfu ar gyfer toriad o 95 y cant yn unig, nid ar gyfer sero net. Ym mha ystyr, felly, ydych chi wedi ymrwymo i sero net yn lle'r gostyngiad o 95 y cant? A wnewch chi hefyd - ? Gwn nad oeddech chi'n gallu gwneud hynny'r wythnos diwethaf ac, os na allwch chi nawr, a fyddech o bosib yn gallu rhoi amserlen i mi o ran pryd y gallwch wneud hyn - beth yw eich polisi chi o ran gwrthbwyso rhyngwladol? A fydd hyn yn cael ei ganiatáu ac, os felly, a fydd terfyn yn cael ei osod arno? Credaf fod eich datganiad heddiw yn amserol iawn, ar ôl y bleidlais yn Nhŷ'r Cyffredin - neu dim pleidlais yn Nhŷ'r Cyffredin neithiwr; aeth drwodd heb bleidlais hyd yn oed - i newid y gostyngiad o 80 y cant hyd at y swm llawer uwch hwn. Tybed beth fydd cost hynny. Mae gennym o leiaf amcangyfrifon lled-swyddogol o £50 biliwn neu £70 biliwn y flwyddyn, ac rwy'n credu ei bod yn llawer mwy synhwyrol canolbwyntio ar y gost flynyddol na'i hychwanegu dros gyfnod anhysbys i gael rhifau brawychus o £1 triliwn a throsodd. Ond, os yw hyn yn £50 biliwn neu £70 biliwn y flwyddyn, yna rwy'n croesawu'r broses hon o bennu cyllidebau carbon, o edrych ar oblygiadau hyn, oherwydd credaf ei bod yn hawdd iawn i wleidyddion wneud ymrwymiadau mawr am amser maith yn y dyfodol i lunio etifeddiaeth i Theresa May neu beth bynnag fo'r cymhellion eraill. Ond dim ond pan wneir y gwaith o edrych ar beth yw goblygiadau hyn, beth yw'r costau, pa gyfaddawdu fydd, yr ydych chi, mewn gwirionedd, yn ymwneud â pholisi gwirioneddol. Ac rwy'n credu, gyda gostyngiad o 40 y cant mewn allyriadau carbon deuocsid ledled y DU ers 1990, roeddem ni'n arwain y byd ac yn cymryd camau gwirioneddol sylweddol yn y maes hwn. Rwy'n gofidio, drwy wthio hynny o 80 y cael datgysylltiad eto rhwng uchelgais a'r diriaethol, neu'r hyn y byddai ein hetholwyr ni'n barod i'w dderbyn yn y maes hwn, o gofio'r cyfaddawdu dan sylw. Roeddech chi'n sôn bod angen glo ym Mhort Talbot i wneud dur. Sut, felly, fyddwn ni'n datgarboneiddio'r broses honno wrth gadw'r diwydiant? Beth yw'r bwriad o ran boeleri nwy? Er mwyn dod yn agos ati, mae'n rhaid ichi gael gwared ar foeleri nwy pawb. A ydych chi'n bwriadu eu disodli nhw gyda rhai trydan - sy'n costio deirgwaith yn fwy ar hyn o bryd - neu a fyddech chi'n cael hydrogen yn lle hynny, ac, os felly, sut ar y ddaear y bydd rhywun yn cyrraedd sefyllfa lle mae rhywun yn torri'r cyflenwad nwy ac yn rhoi hydrogen rhyw dro yn ei le? Sut ydych chi am gyd-drefnu boeleri pobl ar gyfer hynny? Ac a gaf i ofyn ichi, yn olaf, egluro ychydig ymhellach y pwynt hwn am gynhyrchu trydan? Beth yw eich rhagdybiaeth chi o ran yr hyn sy'n mynd i ddigwydd gydag Aberddawan B sydd mor enfawr ei oblygiadau yn y maes hwn, ac a ydych chi'n dweud hynny fel polisi gan Lywodraeth Cymru yr hoffech chi weld mwy o bwyslais ar hunan ddigonolrwydd a llai o allforio trydan i Loegr? Beth sydd o'i le ar allforio ynni i Loegr? A yw hynny'n beth drwg? Os felly, beth ydych chi'n bwriadu ei wneud yn ei gylch?
