I don't think I am presenting outliers (though I have edited the list to add some context).

US+China+Europe+Australia have cumulatively emitted 70% of all historical emissions. They are still 3x the world average and the estimated target. That's why they are on the list.

China is there because it is a common villain in these discussion. The low-(middle)-income countries are, in my opinion, never going to emit much more than they do now. They will never contribute to the problem but will feel all the effects.
