English: I don't think that's a fair comment, given some of the projects that we are currently funding in south-west Wales and given the developments that are currently in train, particularly with regard to the Swansea bay metro programme. The decision will be for the First Minister, but a debate will take place, and that debate will, I'm sure, see a number of alternative expressions of interest given and a number of alternative ideas for how we resolve the M4 congestion around Newport. This is a very divisive issue - I respect that - but the decision must be evidence based, and when we look at the evidence available to us, the benefit-cost ratio of the proposal is classed as high, particularly when you compare it to some of the other major infrastructure projects that are taking place or have taken place across the UK. It emerges favourably when you compare it, for example, to the A303 Stonehenge bypass, which was given a BCR of just 1.3, or the A470, 1.05. However, in recognition of the different views around the Chamber and the need to ensure that we invest in alternative means of travelling, it's fair to say that we need to look at car sharing schemes as well as personalised travel plan schemes and active travel wherever and whenever we can, because it's an interesting fact that, with car sharing schemes, there's a BCR of between 1.95 and 6, and personalised travel plans, 4.5 to 31.8. Active travel provides a very high BCR as well and that's part of the reason why we decided in Government to significantly increase our spending on active travel, in order to accelerate the development and delivery of active travel routes that offer an alternative means of getting people from A to B.
Welsh: Ni chredaf fod hwnnw'n sylw teg, o gofio rhai o'r prosiectau a ariennir gennym ar hyn o bryd yn ne-orllewin Cymru, ac o ystyried y datblygiadau sy'n mynd rhagddynt ar hyn o bryd, yn enwedig ar raglen fetro bae Abertawe. Y Prif Weinidog fydd yn gwneud y penderfyniad, ond bydd trafodaeth yn digwydd, a bydd y drafodaeth honno, rwy'n siŵr, yn amlygu nifer o wahanol ddiddordebau a nifer o syniadau gwahanol ynglŷn â sut y gallwn ddatrys y tagfeydd ar yr M4 o gwmpas Casnewydd. Mae hwn yn fater cynhennus iawn - rwy'n parchu hynny - ond mae'n rhaid gwneud y penderfyniad ar sail tystiolaeth, a phan edrychwn ar y dystiolaeth sydd ar gael i ni, nodir bod cymhareb cost a budd y cynnig yn uchel, yn enwedig o gymharu'r prosiect â rhai o'r prosiectau seilwaith mawr eraill sydd ar y gweill neu sydd wedi digwydd ledled y DU. Mae'n edrych yn ffafriol pan fyddwch yn ei gymharu, er enghraifft, â ffordd osgoi Côr y Cewri ar yr A303, a gafodd gymhareb gost a budd o 1.3 yn unig, neu'r A470, ar 1.05. Fodd bynnag, i gydnabod y safbwyntiau gwahanol o amgylch y Siambr a'r angen i sicrhau ein bod yn buddsoddi mewn dulliau amgen o deithio, mae'n deg dweud bod angen inni edrych ar gynlluniau rhannu ceir yn ogystal â chynlluniau cynllun teithio personol a theithio llesol lle bynnag a pha bryd bynnag y gallwn, oherwydd mae'n ffaith ddiddorol, gyda chynlluniau rhannu ceir, y ceir cymhareb gost a budd o rhwng 1.95 a 6, a rhwng 4.5 a 31.8 ar gyfer cynlluniau teithio personol. Mae teithio llesol yn darparu cymhareb gost a budd uchel iawn hefyd, ac mae hynny'n rhan o'r rheswm pam ein bod wedi penderfynu yn y Llywodraeth i gynyddu ein gwariant ar deithio llesol yn sylweddol, er mwyn cyflymu'r gwaith o ddatblygu a darparu llwybrau teithio llesol sy'n cynnig dewis amgen i bobl ar gyfer teithio o le i le.
