Rwy’n sylweddoli nad yw £20m yn ddigon o bell ffordd i ddatgarboneiddio cartrefi Cymru. Mae pawb yn cydnabod y bydd angen symiau sylweddol o arian, a gwelwyd drwy brofiad nad taflu arian at y broblem yw’r ateb. Mae angen i ni ddeall beth sy'n gweithio gyntaf. Daw'r rhan fwyaf o gost ôl-osod o ffynonellau preifat ac nid arian cyhoeddus, ac felly mae'n hanfodol ein bod yn dysgu sut i ôl-osod cartrefi'n dda er mwyn rhoi hyder i fuddsoddwyr. Bydd y rhaglen hon yn rhoi darlun llawer cliriach i ni o'r gwir gostau ac yn creu'r dull gweithredu a diwydiant i ddatgarboneiddio pob un o'r 1.4 miliwn o gartrefi yng Nghymru erbyn 2050.
I am not going to pretend that £20m is going to come anywhere close to decarbonising Welsh homes. Everyone recognises that huge amounts of money will be needed. And experience shows that throwing money at the problem just does not work.  We need to understand what works first.  Most of the cost of retrofit will come from private sources and not the public purse, it is therefore essential that we learn how to retrofit homes well to give confidence to investors. This programme will give us a much clearer picture about the true costs and create the approach and an industry to decarbonise all 1.4 million homes in Wales by 2050.
