> Instead there should be a tax on taking carbon out of the ground or importing it into the country. Doesn't that have the same problem? Anything energy intensive just shifts outside of the borders of that country where the tax is enforced. IMO, carbons taxes need to be built into the trade deals. You need to say "we're creating a level playing field between our countries, but we do that on the basis that we are both going to do our bit to solve common problems". The major reason tackling climate change is difficult is because it is a tragedy of the commons.
