Carbon taxes should be uncontroversial. They're economically sound and use levers we already have and trust to control other aspects of society without much debate (sin taxes are widely used despite the odd objection). But people on the extreme eco-warrior end are suspicious because they look like paper-pushing without doing anything, and people on the extreme capitalist-growth end dislike them because they will in fact be disruptive. It takes a kind of well-intentioned pragmatism that I think is rare - one tends to get selfish pragamtism, or else well-intentioned idealism/fanaticism.
