Zero if it runs off solar.

  I'm not sure if it's an actual issue but solar panels are quite dark and get really hot. I could imagine that a huge solar array does measurably heat the immediate surrounding area.

    Even if it were true, it doesn't produce extra CO2.

      Sure, but a solar powered A/C system is well out of the price range of a few billion people on earth.
