Agree 100%. Tax generation of CO2 at the energy level and all else should follow. Then allow companies to get a tax reduction if they offset their output in some well researched and supported method. Tadaa...
Clearly, that would lead to mass hysteria and societal collapse.

A ton is 2000 pounds. A gallon of gasoline emits 20lbs of co2 when burnt (most of the weight is in the o2, so the emissions are heavier than the gasoline).
Divide the per ton prices by 100 to convert to per gallon of gas, and you get $0.50-$2.00.
The existence of the tax would ensure they all had enough revenue to scale; fund them all initially, then let economics pick the winner.
