That only tells us China produces lower-margin goods. It isn't surprising that a developed country has higher labor productivity than a developing or middle-income one. Using that to decide whose carbon emissions are "fairer" is a fools errand.
Yes, but I think gross output as % of global share still illustrative proxy of how much resource intensive physical goods are produced relative to emissions. That's closer to maximizing "production" than using GDP/value added as % of global share which is proxy for maximizing "value".
