It is relevant though, because it's about what's accelerating climate change.
It's not about what a regime believes they're owed in terms of rapid growth or taking their turn at the wheel of global hegemony or anything else. Humanity doesn't have the runway left for geopolitical games.
I'll answer the question for you since you are unwilling to acknowledge; the climate does not care about per capita emissions, only the totality of what's dumped into the atmosphere matters.
