An A320 suffered the loss of the green hydraulic system. The flight crew complied with the appropriate checklists; declared an emergency and landed at their destination.

Narrative

The First Officer disengaged the autopilot and made the turn toward final and used a little speed brake to aid the descent. At that time we got an ECAM for Green System low hydraulic quantity. I accomplished the ECAM by turning off the PTU and the green (#1) system engine pump. This gives you a second ECAM Green Sys Low Press. I decided it best for me to fly the aircraft and coordinate with ATC while the First Officer worked the ECAM. He also referenced the flight manual for any notes/warnings/cautions. I declared an emergency with ATC and notified the company. I also asked for some delay vectors to give us a little more time to work the problem. We had about 4600 lbs of fuel at this point so we didn't have a lot of extra time to work with. I gave a cabin advisory to the Lead Flight Attendant and since we had a deadheading Airbus Captain on board I had him come to the cockpit to back us up on anything we might have overlooked or anything else we might consider. Satisfied; we told ATC we were ready for the approach. The landing gear free fell as advertised and we landed uneventfully. I was able to make the turn off the runway; but with no nosewheel steering stopped clear of the runway. We started the APU; shut down the engines; let the fire department check the aircraft and; given the okay; were towed to the gate.
