Let me clariify, upper air pollution from the planes CO2. Obviously some ground air pollution as well but so do all the automobiles and power plants. As far as the glycol I don't see that as a major issue. In fact, they have a tractor attached to it is a large tanker with a vacuum that as the planes are de-iced the glycol remaining gets suck up into the tanker. Further more, the airport expanding is not going to change the glycol levels used. So, in the sense airports are pollluters due to the greenhouse gases.
