That "water waste" requires molecular hydrogen, and producing that requires energy. The real waste is coming out of some power plant.

The altitude where the waste is exhausted matters too. For instance, the GHG forcing from your everyday airliner is about 3x compared to the same amount of CO2 and H20 exhausted at sea level. This difference is almost entirely due to the H20, IIRC there's no altitude dependence in CO2 emissions.
