Er bod toriadau i allyriadau nwyon t\u0177 gwydr yng Nghymru, hyd yma, wedi cyrraedd y targed ar y llwybr i fod yn sero-net erbyn 2050, i wneud cynnydd pellach bydd angen newidiadau economaidd a chymdeithasol sylweddol ynghyd \u00e2 lleihad enfawr mewn allyriadau dros y deng mlynedd nesaf.<\/p>\n

Mae Canolfan Polisi Cyhoeddus Cymru (WCPP) wedi derbyn cyllid gan Lywodraeth Cymru i roi cymorth annibynnol i Gr\u0175p Her Sero-Net 2035 Cymru, sy\u2019n cael ei gadeirio gan y cyn-weinidog Jane Davidson, i helpu\u2019r Grwp i gael gafael ar dystiolaeth ac arbenigedd perthnasol i oleuo eu gwaith.<\/p>\n

Mae ein hadroddiad rhagarweiniol ar gyfer y Gr\u0175p yn rhoi trosolwg ar y tueddiadau presennol o ran allyriadau yng Nghymru, a\u2019r llwybrau i gyrraedd sero-net a fodelwyd gan Bwyllgor Newid Hinsawdd (CCC) y DU, gan drafod y cwestiynau ymchwil canlynol:<\/p>\n

1. Beth yw cynnydd presennol Cymru tuag at gyrraedd ei thargedau allyriadau?
\n2. Beth yw\u2019r prif ffynonellau atal allyriadau a ddisgrifiwyd yn \u2018llwybr cytbwys\u2019 y CCC ar gyfer Cymru, hyd at 2035 a hyd at 2050?
\n3. Beth yw goblygiadau posib ceisio cyflymu\u2019r rhain?<\/p>\n

Mae ein hadroddiad yn disgrifio\u2019r tueddiadau presennol a hanesyddol o ran allyriadau, cyn rhoi trosolwg ar senario llwybr cytbwys y CCC i Gymru a dadansoddiad manwl o\u2019r llwybrau i leihau allyriadau nwyon t\u0177 gwydr ar gyfer chwech o\u2019r prif sectorau allyriadau: cynhyrchu trydan, gweithgynhyrchu ac adeiladu, adeiladau preswyl, amaethyddiaeth, trafnidiaeth ar yr wyneb, a defnydd tir, newid defnydd tir a choedwigaeth (LULUCF).<\/p>\n

Mae\u2019r rhan fwyaf o allyriadau yn y blynyddoedd diwethaf wedi dod drwy ddatgarboneiddio cynhyrchu trydan, ond ychydig iawn o gynnydd a wnaed mewn sectorau eraill. O\u2019i gymharu \u00e2\u2019r DU i gyd, mae\u2019r sectorau amaeth a thrafnidiaeth ar yr wyneb yn cyfrif am gyfran fwy o gyfanswm allyriadau Cymru sy\u2019n golygu y bydd llwyddo neu fethu \u00e2 datgarboneiddio\u2019r sectorau hyn yn cael mwy o effaith yn gyfrannol ar gynnydd Cymru.<\/p>\n

Mae ein hadroddiad hefyd yn trafod tybiaethau ynghylch faint o newid cymdeithasol sy\u2019n bosib o fewn yr amser, yn hytrach nag atebion technolegol sy\u2019n sbardun allweddol i leihau allyriadau yn llwybr cytbwys y CCC.<\/p>\n

Mewn darn trafod cysylltiedig, a baratowyd ar gyfer y Gr\u0175p cyn eu cyfarfod cyntaf yn Ionawr 2023, myfyriwn ychydig ar natur y dasg sy\u2019n wynebu\u2019r Gr\u0175p wrth ystyried sut y gallai Cymru gyflymu\u2019r broses o bontio at sero-net, gan gyflwyno hefyd rai o\u2019r cymhlethdodau, heriau a chyfleoedd a chynnig cyngor ar sut orau i fynd i\u2019r afael \u00e2\u2019r pethau hyn. Mae Cydymaith Ymchwil gyda\u2019r WCPP, Josh Coles-Riley, hefyd wedi cyhoeddi blog ar ein hadroddiad yng nghyd-destun adroddiad cynnydd diweddaraf CCC ar gyfer lleihau allyriadau yng Nghymru.<\/a><\/p>\n

Mae\u2019r dadansoddiad a\u2019r casgliadau a gyflwynir yn yr adroddiad, blog a\u2019r darn trafod yn rhai\u2019r awdur ei hun ac nid ydynt yn cynrychioli barn na safiadau Gr\u0175p Her Sero-Net 2035 Cymru.<\/p>\n","protected":false},"excerpt":{"rendered":"
