Following the outcome of this consultation, and an extensive period of stakeholder engagement on potential alternative approaches, a decision was made to introduce regulations on an all-Wales basis.
Yn dilyn canlyniad yr ymgynghoriad hwn, a chyfnod helaeth o ymgysylltu â rhanddeiliaid ar ddulliau gweithredu amgen posibl, penderfynwyd cyflwyno rheoliadau ar sail Cymru gyfan.
