On final approach; we lost the green hydraulic system. We entered holding to complete the non-normal procedure and get fully configured. We also requested a longer runway and emergency equipment. The landing was made to a full stop because of loss of normal brakes and nose wheel steering. We were then towed to the gate.
We experienced a mechanical failure (HYD G SYS LO PRESS) upon our descent into ZZZ on the ZZZZZ1 Arrival beginning approximately outside ZZZ waypoint. I was Pilot Flying; the Captain followed appropriate ECAM actions and checklists following company procedures. We advised ATC based on this ECAM considering our location and situational aspects.  We elected to hold over the final approach fix for GPS approach to Runway XX while we completed all of our necessary actions in the interest of safety. Upon completion of these duties; we exited the hold; completed approach and landed successfully coming to full stop on the runway. Based on the mechanical condition of the aircraft as result of systems lost from hydraulic system; we coordinated with company operations to tow us in due to loss of nose wheel steering and deplaned normally. Mechanical malfunction (HYD G low pressure) ECAM.
A320 flight crew reported the loss of the green hydraulic system resulted in a precautionary landing and a tow to the gate.
