Er mwyn helpu i gyfrannu at yr ymgyrch, rydym wedi comisiynu ymchwil ynghylch ymwybyddiaeth ac agweddau cyhoeddus i'r newid ac maent wedi dangos eu cefnogaeth gynyddol a chryf fesul chwarter. Mae'r ymchwil hefyd wedi'i defnyddio i dargedu gweithgarwch cyfathrebu trwy'r cyfnod o ddwy flynedd. Rydym hefyd wedi cyhoeddi canfyddiadau diweddaraf yr arolygon hyn.
To help inform the campaign, we have commissioned research around awareness and public attitudes of the change. These have been shown to be increasingly and strongly supportive quarter on quarter. The research has also been used to target communications activities throughout the two year period.  We have also published the most recent findings from these surveys.
