English: Yes, as Mike Hedges says, he has long been a champion of invest-to-save and also innovate-to-save, and has been actually very challenging in terms of how are we demonstrating that this good practice travels. So, as a result of that, we did commission Cardiff University to undertake a piece of research for us so that we could really understand the experiences of those schemes. There were some particular barriers for the travelling of good practice that were identified as a result of that research, including the availability of the finance - so, once a scheme comes to an end, do other organisations have the ability to undertake similar work? Obviously, there are some things that we can look at there in terms of responding to that. The availability of staff resources with the right skills to implement change was another challenge, alongside senior leadership support for the implementation of change, the willingness to take risks and the extent to which they take on board evidence from other schemes, and then finally contractual commitments, of course, which might mean some changes would incur financial penalties if they were broken. So, those are challenges that that piece of research has recently identified for us, and which we need to consider now as we start moving forward with schemes. But I will say that in 2022-23 we are investing in a significant carbon reduction project in Cardiff and Vale University Health Board, and that follows on from many of the other initiatives in health boards across Wales in respect of carbon reduction, so we've learned from those smaller schemes and are now implementing it in a larger scheme. And our focus now is on proposals that further the programme for government agenda, and we'll be using the experience from those past schemes to help these initiatives, and I look forward to providing an update on these before too long.
Welsh: Ie, fel y dywed Mike Hedges, mae wedi cefnogi buddsoddi i arbed ers amser maith ac arloesi i arbed hefyd, ac mae wedi herio'r modd y dangoswn fod yr arferion da hyn yn teithio. Felly, o ganlyniad i hynny, fe wnaethom gomisiynu Prifysgol Caerdydd i wneud ymchwil ar ein rhan fel y gallem ddeall yn iawn beth yw'r profiadau a gafwyd o'r cynlluniau hynny. O ganlyniad i'r ymchwil honno, nodwyd bod rhwystrau penodol o ran y modd y mae arferion da yn teithio, gan gynnwys argaeledd y cyllid - felly, ar ôl i gynllun ddod i ben, a oes gan sefydliadau eraill allu i wneud gwaith tebyg? Yn amlwg, mae rhai pethau y gallwn edrych arnynt mewn ymateb i hynny. Roedd argaeledd adnoddau staff gyda'r sgiliau cywir i weithredu newid yn her arall, ochr yn ochr â chymorth uwch arweinwyr i weithredu newid, parodrwydd i gymryd risgiau ac i ba raddau y maent yn ystyried tystiolaeth o gynlluniau eraill, ac yna'n olaf, ymrwymiadau cytundebol wrth gwrs, a allai olygu y byddai rhai newidiadau'n arwain at gosbau ariannol pe baent yn cael eu torri. Felly, mae'r rheini'n heriau a nodwyd gan yr ymchwil honno yn ddiweddar, heriau y mae angen inni eu hystyried yn awr wrth inni ddechrau datblygu cynlluniau. Ond rwyf am ddweud ein bod yn buddsoddi mewn prosiect lleihau carbon sylweddol ym Mwrdd Iechyd Prifysgol Caerdydd a'r Fro yn 2022-23, ac mae hynny'n dilyn llawer o'r mentrau eraill mewn byrddau iechyd ledled Cymru sy'n ymwneud â lleihau allyriadau carbon, felly rydym wedi dysgu o'r cynlluniau llai hynny ac rydym bellach yn ei weithredu mewn cynllun mwy. Ac rydym yn canolbwyntio yn awr ar gynigion sy'n hyrwyddo agenda'r rhaglen lywodraethu, a byddwn yn defnyddio'r profiad o'r cynlluniau blaenorol hynny i helpu'r mentrau hyn, ac edrychaf ymlaen at roi'r wybodaeth ddiweddaraf am y rhain cyn bo hir.
