> A rational approach to climate change consists of accounting for GHG emissions where they are and cutting them where they are The problem here is that would require an enormous international agreement. I do not see the political will for this in the largest polluters (US, China) and corruption would be a major problem in large parts of the world. Doing this on anything less than a global scale would lead to unintended side effects where importing from country A get cheaper because A does not tax GHG emissions, just replacing the emissions. You could theoretically fix this at the border with tarifs, but determining how much emissions a particular product caused becomes real hard real quick.
