Narrative:

We received a green hydraulic reservoir low press ECAM. We contacted maintenance control and they thought it might be a sensor since we still had 3000 psi. About an hour later we received a low pump pressure so we followed the ECAM and shut down the green pump. We contacted company and notified the flight attendants we will be towed off the runway. We declared an emergency to make sure the ground was prepared in case of any unseen items. We landed and moved off the runway without incidence. We were then towed to the gate.
