I don't agree that a carbon tax would be an economy killer if it replaced a different tax instead of being applied on top of existing taxes. In fact, the good thing about a carbon tax is not that it addresses climate change (it doesn't, unless we're talking about taxing carbon across the entire developed and developing world). It's that it shifts a portion of our tax system away from production onto consumption and because it stands as a price proxy for the national security expenses we incur to keep the global oil trade flowing.
