Wel, nid oes angen brathu yn ôl, Prif Weinidog. Chi sydd 'r cyfrifoldeb. Chi sydd â'r cyfrifoldeb, roedd yr arian gennych chi ac fe gawsoch chi'r dewis i'w wneud. Pam nad ydych chi wedi ei wneud?

Well, there's no need to bite back, First Minister. You have the responsibility. You have the responsibility, you had the money and you had the choice to do it. Why haven't you done it?

Diolch. Roedd gennym ddull gwell o gyflwyno, ac mae hynny wedi arwain at gyfraddau goroesi gwell ymhlith y llyslau, sy'n ddatblygiad allweddol wrth fynd i'r afael â chlymog Japan. Cawsom ollyngiadau pellach yn gynharach eleni. Ar hyn o bryd, mae Prifysgol Abertawe yn dadansoddi canlyniadau'r treialon rheolaeth gemegol ar wahân, y byddwch yn ymwybodol ein bod wedi eu cefnogi - treial dwy flynedd gan Brifysgol Abertawe. Edrychaf ymlaen yn fawr at ddarllen eu hadroddiad.

Thank you. We had an improved delivery method, and that has resulted in better survival in the insect psyllids, which is a key development in tackling Japanese knotweed. We had further releases earlier this year. Swansea University are currently analysing the results from the separate chemical control trials, which you'll be aware we supported - a two-year trial by Swansea University. I very much look forward to reading their report.

Dirprwy Lywydd, yr ateb i'r ddau beth hynny yw 'gwnaf', ac adroddaf yn ôl i Rhianon Passmore wrth i ni ystyried y sylwadau y mae wedi'u gwneud.

Deputy Presiding Officer, it's a 'yes' to both of those things, and I will report back to Rhianon Passmore as we consider the points that she's made.

Mae'r rhan fwyaf, os nad pob un, o'r busnesau cymunedol, mentrau cydweithredol a mentrau cymdeithasol hyn yn blaenoriaethu cynaliadwyedd a diogelu'r amgylchedd fel elfennau craidd o'u modelau busnes. Yn Nhyddewi, er enghraifft, Câr-y-Môr yw'r fferm gefnfor adfywiol gyntaf sy'n eiddo i'r gymuned yng Nghymru. Mae'n gymdeithas er budd cymunedol, gyda dwy nod allweddol: gwella'r amgylchedd arfordirol a chreu swyddi cynaliadwy. Ac mae'r bwyd môr y mae'n ei gynhyrchu yn gynaliadwy ac yn flasus dros ben, a dwi'n siarad o brofiad ar ôl bod yno gyda Mabon dros yr haf. Mae Ynni Sir Gâr yn un o nifer o brojectau ynni cymunedol sy'n gweithio i leihau costau ynni, mynd i'r afael â thlodi tanwydd a chynhyrchu ynni glân, adnewyddol. Felly, mae gan fentrau cymdeithasol a chymunedol hefyd ran bwysig i'w chwarae wrth gyrraedd targedau amgylcheddol allweddol.

The majority, if not all, of the community businesses, co-operative enterprises and social enterprises prioritise sustainability and protecting the environment as core elements of their business models. In St Davids, for example, Câr-y-Môr is the first regenerative ocean farm under community ownership in Wales. It's a community benefit society that has two key objectives: improving the coastal environment and creating sustainable jobs. And the seafood that it produces is sustainable and very delicious, and I speak from experience, having been there with Mabon over the summer. Ynni Sir Gâr is one of many community energy schemes that work to decrease energy costs, to tackle fuel poverty and to produce clean, renewable energy. So, social and community enterprises also have an important part to play in meeting key environmental targets.

Buaswn i'n gobeithio y byddai'n gofyn i fi, ond beth sy'n bwysig yw - . Roedd e'n ddiddorol; roedd yna adroddiad wedi dod mas ychydig o flynyddoedd yn ôl, lle roedd yna syniadau wedi dod ymlaen ynglŷn ag efallai canolbwyntio ar ychydig o ganolfannau - so, Aberystwyth, Bangor a rhywle arall -

I would hope that he would ask me, but what's important - . It was interesting; there was a report published a few years ago where there were some ideas proposed about focusing on certain centres - Aberystwyth, Bangor and a few others -
