That can't be true if the result is lower CO2 emissions.
Also, I'm pretty sure that you're not going to compensate small scale CO2 sequestration. (It would be too costly to do so, but the result is the same - your scheme can't treat all CO2 the same even though your reason for taxing CO2 says that it is.)
You're still going to tax me....
> The level of the tax should be chosen so
In other words, "lump it".
