During cruise; we received an ECAM message stating that pressure in the Green Hydraulic system was low. We followed the appropriate ECAM actions as directed; and elected to return to ZZZ airport. Other than the loss of ground nosewheel steering associated with the Green Hydraulic system; the remainder of the flight and landing was routine and uneventful. This was a mechanical/system malfunction. It would be impossible to anticipate again. Proper emergency and checklist procedures as followed will continue to be the best course of action in any future events.
A319 First Officer reported low quantity on Green Hydraulic System caused an air turnback and precautionary landing.
