It's because in general I believe tax money is not utilized effectively and their impact on demand is minimal. Non-tax policies could have similar effects. For example the government could impose a ban on manufacturing SUV vehicles or improve the public transport system. Increasing the age at which one could get a driver's license in the USA would probably reduce petrol consumption by a few percent (as more families have more than one car).
What evidence do you have that the money received in tax would not purchase goods and services that would increase emissions?
I never made an axiom that no good policy involves taxation. It was your assumption. The least you could have done was to ask me to clarify my position.

Eh? Where did I say or imply that it wouldn't? I asked why you're so sure that taxation couldn't be part of the best policy. I didn't say I'm sure that it should be. I don't know what the best policy is.
(In any case, surely what's relevant is not whether any tax revenue would go to purchasing things that increase emissions, but whether the net effect would be an increase in emissions.)

You might want to remind yourself of the meaning of the word "if".
