Departing ZZZ on the ZZZZZ departure and above 10;000 MSL ECAM indicated a loss of the Green Hydraulic System/Hydraulic System Pressure Low. Followed ECAM procedure and followed up with appropriate QRH procedure which included gravity fall of the landing gear and loss of nose wheel steering. Dispatch was notified of intent to declare an emergency; flight attendants were briefed and brief description of situation provided to the passengers. [Advised] with ATC and coordinated with dispatch for emergency equipment to be available upon arrival at ZZZ1. Requested relief from ATC from the ZZZZZ1 STAR and requested an ILS to Runway XXR. Landed without incident and cleared Runway XXR at Intersection Q. Stopped between runways XXL and XXR and waited for tow to gate.  Following arrival debriefed with all crew members aboard.
We were climbing out of ZZZ going directly to ZZZZZ on the ZZZZZ1 departure off Runway XXL. We were above 10;000 [feet] but not yet to FL230. We got an ECAM: HYD G RESV LOW LEVL. CA flew the plane and I did the ECAM. After completing the ECAM; I went through the QRH procedures. We were handed off to Center and we checked in. We had a Jump seater; a 757 Captain who had also flew the Airbus before and was a great asset. Between us all; we discussed our options. After considering it all we decided to continue to ZZZ1 and we [advised] with Center; gave them fuel and SOB. We continued and got priority on the arrival and approach. We performed the manual gear extension QRH and configured early due to the slow movement of flaps and slats. The Captain flew the approach flawlessly and landed perfectly. We were able to clear the runway and hold short of [Runway] XXR and then towed to the gate.
Flight crew stated failure of the Green Hydraulic system caused loss of hydraulic gear extension and nose wheel steering; resulting in an priority landing.
