The idea is to make it potent enough to affect the behaviour of those 95% of the population that's responsible for 75% of the emissions (I made up that number, happy to be corrected) and whose behavior you can affect with economical nudging. No, they won't like that part. But hopefully the extra income will soften the blow. The idea being that with it, you can either afford some of the high-emission-behavior you were used to. Or you can afford more of the low-emission-behavior than you were used to. Comparatively a lot more, because it's both taxed lower and you have extra income.
