English: I agree entirely with what the Member has said. He recognises the challenges of Brexit. We know that it's impossible to operate effectively on an environmental scale, particularly when it comes to air pollution, simply by looking at Wales or simply by looking at the UK for that matter, or simply by looking at Europe. It's one thing to reduce air pollution in Europe, but if a particular industry relocates to a part of the world where controls are more lax, then it just means that the pollution is being exported to another part of the world and, actually, globally, things are made worse. So, it's hugely important that we influence those areas where we can and, of course, look to keep energy-intensive industry in Wales, while, at the same time, ensuring that they have proper environmental regulations that they follow. In a meeting that I had last week with representatives of the sector, I made it clear to them that was is already enshrined in Welsh law will remain. It will then be a matter for Government over the next few years to decide what it wishes to keep and what it wishes to discard. We're nowhere near the beginning of that process, but we have to understand that it isn't the case that, when the UK leaves the EU, everything falls that ever came from Europe. That clearly isn't the case. It's the same as when the Irish Free State left the UK. It's not as if all the laws fell and there was no law. The laws that were there remained until they were amended in the future by the Dáil at that time. But, it is right to say that we shouldn't lose sight of the good progress that we've made in terms of our environment and the excellent progress, particularly, that's been made in recycling.
Welsh: Rwy'n cytuno'n llwyr â'r hyn y mae'r Aelod wedi'i ddweud. Mae'n cydnabod heriau Brexit. Rydym yn gwybod ei bod yn amhosibl gweithredu'n effeithiol ar raddfa amgylcheddol, yn enwedig ym maes llygredd aer, dim ond drwy edrych ar Gymru neu ddim ond drwy edrych ar y DU o ran hynny, neu ddim ond drwy edrych ar Ewrop. Mae'n un peth lleihau llygredd aer yn Ewrop, ond os yw diwydiant penodol yn adleoli i ran o'r byd lle mae'r rheolau'n fwy llac, mae hynny'n golygu bod y llygredd yn cael ei allforio i ran arall o'r byd ac, mewn gwirionedd, yn fyd-eang, mae pethau'n mynd yn waeth. Felly, mae'n hynod bwysig ein bod yn dylanwadu ar y meysydd hynny lle y gallwn ac, wrth gwrs, yn ceisio cadw diwydiant ynni-ddwys yng Nghymru, gan, ar yr un pryd, sicrhau eu bod yn dilyn rheoliadau amgylcheddol priodol. Mewn cyfarfod a gefais yr wythnos diwethaf gyda chynrychiolwyr y sector, fe'i gwnes yn glir iddynt y bydd yr hyn sydd eisoes wedi'i ymgorffori yng nghyfraith Cymru'n parhau. Yna, mater i Lywodraeth dros yr ychydig flynyddoedd nesaf fydd penderfynu beth maent yn dymuno ei gadw a beth maent y dymuno cael gwared arno. Nid ydym yn agos at ddechrau'r broses honno, ond rhaid inni ddeall nad yw'n wir, pan fydd y DU yn gadael yr UE, bod popeth sydd erioed wedi dod o Ewrop yn disgyn. Yn amlwg, nid yw hynny'n wir. Mae'r un fath â phan adawodd Gwladwriaeth Rydd Iwerddon y DU. Nid yw fel pe bai'r holl gyfreithiau wedi disgyn ac nad oedd cyfraith. Roedd y cyfreithiau a oedd yno'n aros hyd nes iddynt gael eu diwygio yn y dyfodol gan y Dáil ar y pryd. Ond, mae'n wir dweud na ddylem golli golwg ar y cynnydd da yr ydym wedi'i wneud o ran ein hamgylchedd a'r cynnydd rhagorol, yn arbennig, yr ydym wedi'i wneud o ran ailgylchu.
