Ni allaf glywed y Gweinidog Brexit. Caniatewch i'r Gweinidog Brexit gael ei glywed, os gwelwch yn dda.

I can't hear the Brexit Minister. Allow the Brexit Minister to be heard, please.

Na, o ran y costau gweinyddu. Maen nhw'n dweud wrthym ni, wrth y pwyllgor yma, nad ydyn nhw wedi ymgeisio i fod yn rhan o'r system. Na, nid oes cost iddyn nhw wrth ddefnyddio'r straeon, ond mae cost iddyn nhw i fod yn bartner, yn rhan o'r broses yma.

No, in terms of the administrative costs. They told us - this committee - that they hadn't applied to be part of this programme. I know that there's no cost in them using the stories, but there would be a cost in them becoming a partner in this process.

Na, ond mae cyfleustodau yn fater gwahanol iawn, onid ydyn? Rydych chi'n sôn am chasing. Wel, na, mae yna ddeddfwriaeth sydd yn dweud, 'Dyma safonau. Dyma'r gofynion o ran cyfathrebu efo'r cwsmeriaid.' Nid ydy o yn anodd o gwbl - mae o wedi digwydd yn barod mewn meysydd a gan gyrff nad oedd yn gwneud dim ohono fo yn gynt, fel rhai cyrff llywodraeth leol. Ond mae'r ddeddf yn dweud bod yn rhaid iddyn nhw wneud ac maen nhw wedi ymateb i'r her. Ac mi fuasai - . Fel rydw i'n dweud, roedd Scottish Power yn arfer ei wneud o; nid ydyn nhw yn ei wneud o rŵan. Nid ydy o yn anodd. A dweud y gwir, maen nhw'n eithaf basic, y pethau sy'n dod o fewn y safonau yma.

No, but the utilities are a very different matter, because you're talking about chasing. Well, no, there is legislation that states, 'These are the requirements. These are the standards as regards communicating with the customers.' It's not at all difficult - it's happened already in other areas, in organisations that never, ever did anything on it previously, such as some local government bodies. The legislation has said that they have to do it and they've responded to that challenge. And, as I say, Scottish Power used to do it; they don't do it now. It's not difficult. To be honest, they're quite basic, the things that come within these standards.

Y rhybudd amlwg gan gadeirydd Asiantaeth yr Amgylchedd yn Lloegr yw 'addasu neu farw', a gŵyr pob un ohonom nad oes Clawdd Offa yn bodoli mewn perthynas â'r argyfwng hinsawdd. Ond mae angen inni ddod o hyd i atebion yma yng Nghymru ar gyfer realiti byd-eang. I wneud hynny, mae angen y rheolaeth arnom. Mae arnom angen yr ysgogiadau i wneud gwahaniaeth go iawn. Mae gwelliannau i'n trefniadau cyfansoddiadol wedi cael eu rhewi gan y Llywodraeth Dorïaidd yn San Steffan. Tra bo Boris Johnson yn mwynhau paentio yn ei fila foethus, mae'r argyfwng hinsawdd yn arwain at rewlifoedd yn toddi, ac yma, maent yn gwarafun yr offer sydd eu hangen arnom i weithredu.

The stark warning from the chair of the Environment Agency in England is 'adapt or die', and we all know there is no Offa's Dyke when it comes to climate emergency. But we need to find Welsh solutions here for global realities. To do so, we need the control. We need the levers to make a real difference. Improvements in our constitutional arrangement have been frozen by the Tory Government in Westminster. Whilst Boris Johnson is enjoying painting in his luxurious villa, the climate emergency results in glaciers melting, and here we are denied the tools we need to act.
