It's hard to say how it will go. It's entirely possible carbon capture will become cheap enough that a couple of rich countries can just capture all the necessary carbon for the whole globe and it will be a rounding error in their budget. Then other countries can burn all the oil/coal they want and it will only be a local pollution problem rather than an existential risk to the globe.
