Mae'r Grŵp Cynghori Technegol wedi gwneud cyfraniad sylweddol i'r broses ymgysylltu i gefnogi'r gwaith hwn.  Felly, hoffwn nodi fy niolch i'r grŵp am ei waith.  Hoffwn achub y cyfle hwn hefyd i ddiolch yn fawr i Peter Davies am ei gyfraniad sylweddol i hyrwyddo datblygu cynaliadwy yng Nghymru. Yn rhinwedd ei swydd fel cyn-Gomisiynydd Datblygu Cynaliadwy'r DU, fel Comisiynydd Dyfodol Cynaliadwy, drwy ei waith ar ‘y Gymru a Garem’  ac wrth gadeirio'r Grŵp Ymgynghori Technegol, mae wedi chwarae rôl allweddol nid yn unig wrth ddatblygu Deddf Llesiant Cenedlaethau'r Dyfodol (Cymru) 2015, ond hefyd wrth helpu Cymru i arwain y ffordd yn fyd-eang ym maes datblygu cynaliadwy.
The engagement process that has supported this work has included a significant contribution from the Technical Advisory Group.  I would therefore like to place on record my thanks for the work undertaken by the group.  I would also like to take this opportunity to thank Peter Davies for the significant contribution he has made to advancing sustainable development in Wales.  In his role on the former UK Sustainable Development Commission,  as Commissioner for Sustainable Futures for Wales, , through his work on the ‘Wales we Want’ and in chairing the Technical Advisory Group, he has made a driving force not only in the development of the Well-being of Future Generations (Wales) Act 2015, but in helping Wales become a global leader in sustainable development.
