&#62; What evidence do you have that the money received in tax would not purchase goods and services that would increase emissions?<p>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.<p>(In any case, surely what's relevant is not whether any tax revenue would go to purchasing things that increase emissions, but whether the <i>net</i> effect would be an increase in emissions.)<p>&#62; I never made an axiom. [...] It was your assumption.<p>You might want to remind yourself of the meaning of the word "if".<p>&#62; The least you could have done was to ask me to clarify my position.<p>Curiously, that <i>is</i> exactly what I did.
