Gallaf bellach roi gwybod i'r Senedd bod y Grŵp Her Net Sero wedi ei greu ac wedi cynnal ei gyfarfod cyntaf ddydd Mercher 11 Ionawr.  Mae 14 o arbenigwyr technegol wedi ymuno â'r Grŵp, a ddewiswyd o'r byd academaidd, sefydliadau cyhoeddus a phreifat, gydag arbenigedd ar draws pob sector allweddol o'n heconomi. Mae nifer o sylwedyddion yn ymuno â nhw a bydd Canolfan Polisi Cyhoeddus Cymru yn eu cefnogi.
I am now able to inform the Senedd that the Net Zero Challenge Group has been created and held its first meeting on Wednesday 11 January.  Fourteen technical experts have joined the Group, selected from academia, public and private institutions, with expertise across all key sectors of our economy. They are joined by a number of observers and will be supported by the Wales Centre for Public Policy.
