English: As regional Member for South Wales East, I am acutely aware of the need to address the congestion issues around Newport. Now that the relief road has been abandoned, which we have welcomed, we need to look at alternative ways of addressing those specific issues, alongside upgrading our transport infrastructure to make it fit for us as a twenty-first century European nation. Yes, it is regrettable that there was no plan B put forward by the Government, but there's little traction in going over old ground on that point - far better to look to the future. Whatever is done next must be based on clear criteria and informed by the declaration of a climate emergency by this nation. Future plans should also uphold the principles of the future generations Act. As the commissioner herself has said, historically, in cases such as these, it has not been uncommon for the economic benefits of proposals to be given precedence, but this is one of the reasons why legislation was needed to redress the balance. So, let's make good use of that Act. The black route would have failed on these criteria, since it would have crossed four sites of environmental and scientific importance. It would have threatened the habitat of the common crane, which has recently nested in the Gwent levels for the first time since the seventeenth century, and would have released over 500,000 tonnes of carbon dioxide into the atmosphere. To add to this, it would have obviously led to a significant increase in vehicles on the roads, at a time when we want to achieve a reduction in transport emissions. So, a solution that only focuses on facilitating more car usage is plainly not the answer. We in Plaid believe that a hybrid strategy should be pursued, involving multimodal transport options, with a view to addressing the needs of people all over Wales. This hybrid strategy could combine innovative ideas such as smart motorways, where we use technology to influence the flow of traffic; allocated lanes for multi-occupancy vehicles, such as buses, which can also be used as a car-pool lane; we also need to consider smarter use of our current infrastructure in the area. Professor Mark Barry has suggested, for example, flexible working patterns to help alleviate congestion during traditional rush-hour periods. After all, as we've heard a number of times in this Chamber before, it is only 10 per cent of the daily traffic on the route in question that causes the real problem. Freight consolidation - moving freight to rail, or moving freight during the quiet periods - can also provide some respite during this period of congestion. As we raised in our own debate two weeks ago, lessons can be learned from the Scottish example, where the Scottish Government pays grants to companies who decide to transport freight via train, because removing freight from roads reduces not only congestion, but also road traffic accidents. Now, there are so many innovative ideas being put forward by Members of all parties in this debate, and that is the thing that we should be focusing on now; we should be focusing on the future. Over the coming weeks, Plaid Cymru will be setting up a working group to look at solutions to this issue and, as my colleague, Rhun, has already indicated, we would welcome the opportunity to present those findings in due course. Now, it's clear from contributions across the Chamber that the situation cannot be allowed to just get worse - for the good of the people of Newport, but people all over Wales. We have to work together on this. Diolch.
Welsh: A minnau'n Aelod rhanbarthol dros Ddwyrain De Cymru, rwy'n ymwybodol iawn o'r angen i fynd i'r afael â'r problemau tagfeydd o amgylch Casnewydd. Oherwydd y rhoddwyd y farwol i'r ffordd liniaru bellach, yr ydym ni wedi ei groesawu, mae angen inni edrych ar ffyrdd amgen o fynd i'r afael â'r materion penodol hynny, ynghyd ag uwchraddio ein seilwaith trafnidiaeth i'w wneud yn addas i ni fel cenedl Ewropeaidd yn yr unfed ganrif ar hugain. Ydy, mae'n resyn nad oedd cynllun B wedi'i gyflwyno gan y Llywodraeth, ond nid oes unrhyw fudd o rygnu ymlaen ynghylch hynny - gwell o lawer yw edrych i'r dyfodol. Rhaid i beth bynnag a wneir nesaf fod yn seiliedig ar feini prawf clir ac ar ddatganiad o argyfwng hinsawdd gan y genedl hon. Dylai cynlluniau ar gyfer y dyfodol hefyd arddel egwyddorion Deddf cenedlaethau'r dyfodol. Fel y mae'r comisiynydd ei hun wedi ei ddweud, yn hanesyddol, mewn achosion fel y rhain, nid yw hi wedi bod yn anghyffredin rhoi blaenoriaeth i fanteision economaidd cynigion, ond dyma un o'r rhesymau pam yr oedd angen deddfwriaeth i unioni'r fantol. Felly, beth am wneud defnydd da o'r Ddeddf honno. Byddai'r llwybr du wedi methu ar y meini prawf hyn, gan y byddai wedi croesi pedwar safle o bwysigrwydd amgylcheddol a gwyddonol. Byddai wedi bygwth cynefin y garan gyffredin, sydd wedi nythu yn ddiweddar yng ngwastadeddau Gwent am y tro cyntaf ers yr ail ganrif ar bymtheg, a byddai wedi rhyddhau dros 500,000 o dunelli o garbon deuocsid i'r atmosffer. I ychwanegu at hyn, byddai'n amlwg wedi arwain at gynnydd sylweddol mewn cerbydau ar y ffyrdd, ar adeg pan rydym ni eisiau sicrhau gostyngiad mewn allyriadau trafnidiaeth. Felly, mae'n amlwg nad ateb sy'n canolbwyntio'n unig ar hwyluso mwy o ddefnyddio ceir yw'r ateb. Rydym ni ym Mhlaid Cymru o'r farn y dylid dilyn strategaeth gyfun, sy'n cynnwys dewisiadau trafnidiaeth aml-ddull, gyda'r bwriad o fynd i'r afael ag anghenion pobl ledled Cymru. Gallai'r strategaeth gyfun hon gyfuno syniadau arloesol megis traffyrdd rheoledig, lle rydym ni'n defnyddio technoleg i ddylanwadu ar lif y traffig; lonydd dyranedig ar gyfer cerbydau amlfeddiannaeth, megis bysiau, y gellir hefyd eu defnyddio fel lôn ar gyfer ceir gyda mwy na nifer penodol o deithwyr; mae angen i ni hefyd ystyried defnyddio ein seilwaith presennol yn ddoethach yn yr ardal. Er enghraifft, mae'r Athro Mark Barry wedi awgrymu patrymau gweithio hyblyg er mwyn helpu i leihau'r tagfeydd yn ystod yr oriau brig traddodiadol. Wedi'r cyfan, fel yr ydym ni wedi clywed lawer gwaith yn y Siambr hon o'r blaen, dim ond 10 y cant o'r traffig dyddiol ar y llwybr dan sylw sy'n achosi'r gwir broblem. Gall cydgrynhoi nwyddau - symud nwyddau i'r rheilffyrdd, neu symud nwyddau yn ystod y cyfnodau tawel - hefyd liniaru ychydig yn ystod y cyfnod hwn o dagfeydd. Fel y gwnaethom ni grybwyll yn ein dadl ein hunain bythefnos yn ôl, gellir dysgu gwersi oddi wrth yr enghraifft yn yr Alban, lle mae Llywodraeth yr Alban yn talu grantiau i gwmnïau sy'n penderfynu cludo nwyddau ar drên, oherwydd mae symud nwyddau oddi ar y ffyrdd yn lleihau nid yn unig tagfeydd, ond hefyd damweiniau traffig ar y ffyrdd. Nawr, mae cynifer o syniadau arloesol yn cael eu cyflwyno gan aelodau o bob plaid yn y ddadl hon, a dyna'r hyn y dylem ni fod yn canolbwyntio arno nawr; dylem ni fod yn canolbwyntio ar y dyfodol. Dros yr wythnosau nesaf, bydd Plaid Cymru yn sefydlu gweithgor i edrych ar atebion i'r mater hwn ac, fel y mae fy nghyd-Aelod, Rhun, wedi'i ddweud eisoes, byddem yn croesawu'r cyfle i gyflwyno'r canfyddiadau hynny maes o law. Nawr, mae'n amlwg o gyfraniadau o bob rhan o'r Siambr na ellir caniatáu i'r sefyllfa fynd yn waeth - er lles pobl Casnewydd, ond er lles pobl ledled Cymru. Rhaid inni weithio gyda'n gilydd ar hyn. Diolch.
