English: They could indeed travel at different speeds. The point is we don't yet have that many electric cars on the road, and so, in future, of course, yes, they could travel at higher speeds. The other benefit, though, of introducing 50 mph reduced speed limits is that traffic is proven to travel at a more consistent pace, so you don't have the effect of stop-start traffic, which contributes significantly to emissions. On the issue of the blue route, I really, really should just address the issue of this particular solution that some Members are still embracing. The blue route was roundly trashed by the inspector, and if Members haven't had the opportunity to read the inspector's report, I really would urge them to do so and, in particular, with regard to the blue route pages 457 to 459. It did find, during the course of the inquiry, that the blue route would be inadequate, it would be unsustainable, it would cost around about £1 billion, compared to the £350 million that supporters were promoting, and it would contribute more in terms of emissions - nitrogen dioxide in particular - to those people who are already badly affected by the existing road network. The blue route is simply not an option. I think we've been around the manifesto question a number of times, not just today, but previous to today. The manifesto that we drew up was, of course, drawn up in the circumstances that were apparent at that moment in time, based on the evidence that was available to us. There are many Members in this Chamber who have changed their position on the black route and the blue route based on the evidence that has been presented by the inspector. Of course, since 2016, times have changed quite rapidly. We have now, I think, a better grasp and understanding of the climate emergency. I think, also, we have set the bar higher in terms of how we respond to it. We are developing a Welsh transport strategy that will seek to embrace new and emerging technology and respond to the greatest challenge of our time, which is to reduce emissions and to reverse climate change. I think Huw Irranca-Davies summed up brilliantly what the strategy should seek to deliver. It should ensure that people can be more mobile as they wish to be, but not at the expense of our environment and the interests of future generations. I think a number of Members have rightly raised the role that rail has in reducing the reliance on vehicles, and with regard to questions raised by Jenny Rathbone and Alun Davies, I think it's absolutely right that the commission is able to make calls on the UK Government, not just in terms of improvements to our rail infrastructure, but also in terms of service improvements that could reduce the reliance that people have on the motor car and the M4 in particular. For example, the Department for Transport could remove the objection to Grand Union Trains operating express services between Swansea, Cardiff, Bristol and London, again assisting and reducing congestion on the M4. I've been very clear to the commission that it should not fear making those calls of UK Government as well as of Welsh Government. I can tell Members today that with regard to the -
Welsh: Yn wir, gallent deithio ar wahanol gyflymder. Y pwynt yw, nid oes gennym ni gymaint â hynny o geir trydan ar y ffordd eto, ac felly, yn y dyfodol, wrth gwrs, gallent, fe allent deithio ar gyflymder uwch. Y fantais arall, serch hynny, sy'n deillio o gyflwyno terfynau cyflymder gostyngol o 50 milltir yr awr yw y profir bod traffig yn teithio'n fwy cyson, fel nad ydych chi'n cael effaith traffig sy'n aros ac yn cychwyn am yn ail, sy'n cyfrannu'n sylweddol at allyriadau. O ran y llwybr glas, dylwn mewn difrif calon roi sylw i fater yr ateb penodol hwn y mae rhai Aelodau'n dal i'w gofleidio. Cafodd y llwybr glas ei ddiystyrru gan yr arolygydd, ac os nad yw'r Aelodau wedi cael y cyfle i ddarllen adroddiad yr arolygydd, byddwn yn eu hannog i wneud hynny ac, yn arbennig o ran y tudalennau'r llwybr glas 457 i 459. Yn ystod yr ymchwiliad, nodwyd y byddai'r llwybr glas yn annigonol, na fyddai'n gynaliadwy, y byddai'n costio tua £1 biliwn, o'i gymharu â'r £350 miliwn yr oedd cefnogwyr yn ei hyrwyddo, ac y byddai'n cyfrannu mwy o ran allyriadau - nitrogen deuocsid yn benodol - i'r bobl hynny yr effeithir yn wael arnyn nhw eisoes gan y rhwydwaith ffyrdd presennol. Nid yw'r llwybr glas yn ddewis o gwbl. Rwy'n credu ein bod wedi ymdrin â'r cwestiwn maniffesto nifer o weithiau, nid dim ond heddiw, ond cyn heddiw. Roedd y maniffesto a luniwyd gennym ni, wrth gwrs, wedi'i lunio yn yr amgylchiadau a oedd yn amlwg bryd hynny, ar sail y dystiolaeth a oedd ar gael inni. Mae nifer o Aelodau yn y Siambr hon wedi newid eu safbwynt ar y llwybr du a'r llwybr glas yn seiliedig ar y dystiolaeth a gyflwynwyd gan yr arolygydd. Wrth gwrs, ers 2016, mae'r amseroedd wedi newid yn eithaf cyflym. Credaf fod gennym ni bellach ddealltwriaeth a dealltwriaeth well o'r argyfwng hinsawdd. Rwy'n credu, hefyd, ein bod wedi gosod y safon yn uwch o ran sut rydym ni'n ymateb i hyn. Rydym ni'n datblygu strategaeth drafnidiaeth i Gymru a fydd yn ceisio cofleidio technoleg newydd ac sy'n datblygu, ac ymateb i her fwyaf ein hoes, sef lleihau allyriadau a gwrthdroi'r newid yn yr hinsawdd. Credaf fod Huw Irranca-Davies wedi crynhoi'n wych yr hyn y dylai'r strategaeth geisio'i gyflawni. Dylai sicrhau y gall pobl fod yn fwy symudol fel y dymunant fod, ond nid ar draul ein hamgylchedd a buddiannau cenedlaethau'r dyfodol. Credaf fod nifer o Aelodau wedi crybwyll yn briodol y rhan sydd gan reilffyrdd i'w chwarae o ran lleihau'r ddibyniaeth ar gerbydau, ac o ran cwestiynau a godwyd gan Jenny Rathbone ac Alun Davies, credaf ei bod hi'n gwbl briodol bod y Comisiwn yn gallu galw ar Lywodraeth y DU, nid yn unig o ran gwelliannau i'n seilwaith rheilffyrdd, ond hefyd o ran gwelliannau i wasanaethau a allai leihau'r ddibyniaeth sydd gan bobl ar y car a'r M4 yn benodol. Er enghraifft, gallai'r adran drafnidiaeth ddileu'r gwrthwynebiad i'r Grand Union Trains weithredu gwasanaethau cyflym rhwng Abertawe, Caerdydd, Bryste a Llundain, gan eto gynorthwyo a lleihau tagfeydd ar yr M4. Rwyf wedi bod yn glir iawn â'r comisiwn na ddylai ofni gofyn am hynny gan Lywodraeth y DU yn ogystal â chan Lywodraeth Cymru. Gallaf ddweud wrth yr Aelodau heddiw, o ran -
