Taxation is a road to nowhere as rich people will always either find the way to avoid taxes or find the way to throw the costs of those taxes on the poor. This happens with every kind of tax.
The only solution to decrease CO2 emission is to behave in a rational way and use the only practical, tested and available now clean energy source - nuclear power plants. No amount of eco-talk will change reality that neither solar nor wind energy plants will be able to power modern economy. Europe is learning this the hard way right now.
Maybe Europe will do the suicidal jump with the ideas like "Fit for 55", and will kill its economy to lower global emission by 0.05% but the rest of the World, which emits much more CO2 and will emit even more when all production will be moved from Europe to Asia or USA cannot care less.
