Narrative:

FL350 ECAM: 'hydraulic green engine 1 pump low pressure' followed by secondary 'green system low pressure' after performing ECAM procedure. Division of tasks were established. First officer PF. Captain managed communications with dispatcher; maintenance; flight attendants. Dispatch coordination with ATC our aircraft situation and ultimately declared an emergency for us. Election was made to continue to ZZZ (with secondary planning to land short if additional system losses occurred). Crew's discussion and planning centered around our possible manual gear extension; no nosewheel steering; performance; etc. A cabin advisory was requested of the cabin crew. Decision was made for the captain to become PF upon reaching ZZZ TRACON and make the landing. Descent and approach proceeded normally (a longer final was elected). Cancel repeating ECAM about low green pump pressure. On downwind; per ECAM rcl; selected engine 1 hydraulic and ptu on; upon which all hydraulic indications read normal. Gear; flap extensions were normal. Landing and rollout with steering normal. Cleared runway and brought aircraft to stop. Elected to be towed in due to the potential of lost steering. Tow proceeded normal to the gate where parking checklist was completed.

Narrative: FL350 ECAM: 'HYD GREEN ENG 1 PUMP LOW PRESSURE' FOLLOWED BY SECONDARY 'GREEN SYS LOW PRESSURE' AFTER PERFORMING ECAM PROC. DIVISION OF TASKS WERE ESTABLISHED. FO PF. CAPT MANAGED COMS WITH DISPATCHER; MAINT; FLT ATTENDANTS. DISPATCH COORD WITH ATC OUR ACFT SIT AND ULTIMATELY DECLARED AN EMER FOR US. ELECTION WAS MADE TO CONTINUE TO ZZZ (WITH SECONDARY PLANNING TO LAND SHORT IF ADDITIONAL SYS LOSSES OCCURRED).

DECISION WAS MADE FOR THE CAPT TO BECOME PF UPON REACHING ZZZ TRACON AND MAKE THE LNDG. DSCNT AND APCH PROCEEDED NORMALLY (A LONGER FINAL WAS ELECTED). CANCEL REPEATING ECAM ABOUT LOW GREEN PUMP PRESSURE. ON DOWNWIND; PER ECAM RCL; SELECTED ENG 1 HYD AND PTU ON; UPON WHICH ALL HYD INDICATIONS READ NORMAL. GEAR; FLAP EXTENSIONS WERE NORMAL. LNDG AND ROLLOUT WITH STEERING NORMAL. CLRED RWY AND BROUGHT ACFT TO STOP. ELECTED TO BE TOWED IN DUE TO THE POTENTIAL OF LOST STEERING.
