Narrative:

Flight xyz advised me that he had to shut down the APU on account of an oil overtemp indication. The #1 idg (integrated drive generator -- engine driven #1 engine) was already on placard. This made the aircraft a 1 generator operation. The captain indicated that he wanted to continue to xyz, I told him that there was a possibility of fog in xyz by virtue of no temperature/dewpoint spread and that several other airports in the area were in fog. Also I informed him that we were one step away from an emergency with the 1 generator condition. We then broke contact. I began looking at the abnormal/emergency procedures in the afm. The procedure advised landing at the closest suitable airport. I finally re-established verbal communication and cited the afm procedure to the captain. He agreed he should land. I asked the captain of his position and what was the closest usable airport, he told me yyz, yzz. Both yyz and yzz were in VFR conditions. The captain then requested where the nearest maintenance base was to get the aircraft repaired, and I told him either AAA or BBB. He elected to proceed to BBB, and we broke communications again. I then decided to declare an emergency with DDD, because of the captain's decision to overfly other airports that were usable. I wanted to provide him with priority handling. I sent the flight an ACARS message that I had declared an emergency with ATC. The aircraft proceeded onto BBB and landed without incident.
