Narrative:

While in cruise on autopilot at FL370; received a hydraulic G rsvr lo lvl ECAM. Quantity indicator on hydraulic system page showed level in lower amber range. Per ECAM; selected engine 1 green pump switch and ptu to off. Then received multiple system ecams as a result of securing green hydraulic system. I consulted with maintenance control and dispatch. They were briefed of the situation and a decision was made to continue to our destination. The first officer and I then began researching all flight manual considerations for the abnormal landing. We briefed the purser of the situation and declared a cabin advisory with no need for a preparation for evacuation. With our first contact with center; we declared an emergency and received preferential handling for remainder of flight. About this time; a transfer of control of the aircraft was established; as I would be performing the landing. Also at this time I briefed the passengers on the nature of our situation and the expected normal outcome of the flight; with the exception of the need for a tow in to the gate. Based on the current ATIS for our destination; we discussed the most suitable landing runway. We had dispatch notify ATC that we were requesting emergency equipment. We also advised dispatch of the need for a tug; as we anticipated no nosewheel steering upon landing. Once on frequency; we requested a long; slow 20 mile final in order to configure with slow flaps and manual gravity gear extension. Approach and landing were normal. APU was started on final. Cleared runway with differential braking. Stopped aircraft in the run-up pad. Shut down engines; completed checklists and waited for tug to arrive. Tow in to gate was accomplished and aircraft was secured. We were met by maintenance at the gate where it was confirmed that all or most of the G system hydraulic fluid was lost. I felt CRM was outstanding by all involved including flight attendants; flight crew; maintenance control; dispatch and ATC.
