Narrative:

While level at FL330 during climb segment to FL350, the ECAM caution 'hydraulic G reservoir low level' appeared. ECAM action was performed. A return to clt was requested, and an emergency was declared. Follow-up required. ECAM actions were performed during approach which resulted in restoration of system to normal operation. A normal approach and landing were performed.
