I’ve mentioned British Columbia’s carbon tax before. It is “revenue neutral” (or 100% returnable). IMHO, it is the “least bad” “solution” to the (non)problem of CO2 emissions. That is, it’s better than vehicle mileage standards, better than cap and trade, better than banning (whatever), etc.
When it was put into place, income taxes were reduced to get to the “revenue neutral” part. There is no earmarking of the funds. That’s important — the NDP (Socialist) and Green (Watermelon) parties want to earmark the funds for “fighting carbon”. That would turn a “least bad” intervention into a just plain bad tax grab — combined with a complete waste on the expenditure side.
So long as the tax remains “revenue neutral”, it’s not doing a lot of harm; and it has the advantage of neutralizing the most rabid warmists. However, the threat of it turning into just another tax grab hangs over us like the sword of Damocles.
