Senedd briefing on Aberpergwm coal mine

If in mobile view, scroll down for English language version and for PDF downloads of the briefings.


Mae Cymru wedi cymryd camau pendant yn erbyn cloddio am lo yn y blynyddoedd diwethaf. Defnyddiwyd Deddf Cymru 2017 i rwystro estyniad i waith glo brig Nant Helen. Mae angen gweithredu tebyg nawr yn erbyn pwll glo tanddaearol Aberpergwm.

Mae Energybuild Cyf. yn ymestyn ei bwll glo golosg Aberpergwm ac am barhau i wneud hynny tan 2039. Mae hyn yn mynd yn groes i Ddeddf Llesiant Cenedlaethau’r Dyfodol drwy waethygu’r argyfwng hinsawdd a fyddai’n effeithio ar y genhedlaeth nesaf o amgylch y byd, yn ogystal â niweidio enw da Cymru’n rhyngwladol.

Mae gwaith dur Port Talbot yn bwriadu datgarboneiddio drwy drawsnewid i wneud dur newydd o fetel sgrap heb ddefnyddio glo; fel arall bydd yn rhaid iddo gau, gan ddiswyddo ei staff, a’r rhai mewn cadwyni cyflenwi. Does dim lle i fwy o gloddio am lo yn y Gymru fodern.

Mae glo’n cael ei gymysgu yng ngwaith dur Port Talbot ac, o’r herwydd, nid yw cloddio mwy o lo yng Nghymru’n lleihau’r swm a echdynnir mewn mannau eraill. Mae’n rhaid i fwy o lo gael ei fewnforio o hyd i’w gymysgu â glo Cymru mewn gweithfeydd dur, gan allforio rhai o’r problemau amgylcheddol a chynnal diwydiant anghynaliadwy yn hytrach na chwilio am atebion hirdymor.

Mae cyllid Energybuild Cyf. yn dangos y gallai’r cwmni hwn werthu’r pwll os yw’n gallu ymestyn. Gallai’r cwmni newydd wneud y mwyaf o echdynnu glo a gwerthu’r glo i’r cynigydd uchaf, neu ddiswyddo nifer fawr. Mae yna ffyrdd eraill o wneud dur a ffynonellau eraill o hidlo dŵr yn lle glo carreg.

Mae dau gynnig arall i ehangu pyllau glo yng Nghymru y mae angen i’r llywodraeth eu hatal, a hefyd sicrhau bod safleoedd mwyngloddio blaenorol yn cael eu hadfer yn llawn.

Glo yw treftadaeth Cymru, nid ein dyfodol.


Wales has taken decisive action against coal mining in recent years. The Wales Act 2017 was used to block the extension of Nant Helen opencast coal mine. Similar action is now required against Aberpergwm underground coal mine.

Energybuild Ltd are extending its Aberpergwm coking coal mine and want to continue to do so until 2039. This goes against the Well-being of Future Generations Act by worsening the climate crisis which would affect the next generation around the world, as well as damaging Wales’ reputation internationally.

Port Talbot steelworks is looking to decarbonise by converting to make new steel from scrap metal without using coal; otherwise it will have to close, making its staff, and those in supply chains, redundant. There’s no place for more coal mining in a modern Wales.

Coal is blended at Port Talbot steelworks and, as such, mining more coal in Wales does not reduce the amount extracted elsewhere. More coal still has to be imported to be blended with Welsh coal at steelworks, exporting some of the environmental problems and propping up an unsustainable industry rather than looking for long term solutions.

Energybuild Ltd’s finances show that this company may well sell on the mine if it is able to extend. The new company could maximise coal extraction and sell the coal to the highest bidder, or make a large number of redundancies. There are alternative ways to make steel and alternative sources of water filtration to anthracite coal.

There are two further coal mine expansion proposals in Wales which the government needs to prevent, while ensuring that previous mining sites are fully restored.

Coal is Wales’ heritage, it isn’t our future.
