Narrative:

I was pm; and approximately an hour into the flight at cruise fl 380; I performed my systems check and discovered that green system hydraulic fluid quantity gauge was indicating just above minimum level. Approximately hour later; we got an ECAM directing us to turn off the green engine 1 driven hydraulic pump and to also; turn off the ptu which resulted in a loss of the green system. At this point; we were on the arrival and within 20 minutes from landing at our destination ZZZ. We decided that the safest course of action was to [request priority handling] due to the fact that I was flying with a new captain with less than 100 hours. I performed a non normal landing assessment and reviewed the manual gear extension procedure. We had an uneventful landing; with emergency equipment standing by. The captain managed to use asymmetrical thrust to clear the active runway because; we had no nose wheel steering. He then set the parking brake [and] shut the engines down.
