So it seems to me that there's no way to minimize fuel consumption and not minimize CO2 production.

I don't know how gasoline and CO2 are related.
I know that scooter's weight and speed are far smaller than car's, but consumption isn't far smaller. Why ???
Ex: my car weight 1120Kg and I weight 80 for a total of 1200Kg. My friend's scooter weights 120Kg and he weights like me so it's a total of 200Kg. I'm consuming less than 6l/100km while he's consuming more that 3l/100km. Why is the scooter consuming 1/2 of the car and not 1/6 ?
From technical data he's emitting more CO and HC than me...
His scooter is a couple of years old while my car is 11 years old.
In Europe 2-wheelers' efficiency is far smaller than cars' efficiency.
In the absolute you reduce consumption, but not as it should be reduced for the reduced speed and weight.
Scooter's insurances are high : my friend is paying the same amount as I do for my car. You may not save money because you may keep an old car or regularly rent one.
Accident risks are higher for scooters : road are narrower in Europe so when a car is passing over you it's dangerous. I will not change my car for a scooter because I don't want to have an accident with (or without) my 14 months old son.
