except that its still a pointless value.
eg India emits a lot of CO2, and is increasing at a massive rate,
Look at the population demographics of India and you'll see a vast number of those people use almost no power, the rural poor are still practically agrarian-age peasants.
So the idea per-capita is about fairness is stupid, the rich elites and business consumes it all. eg you can have a hypothetical country comprised of 1 king in his hunger-games capital and a million peasants shivering in the cold, but per-capital says that country is perfectly fair usage.
so if India is emitting all this CO2 and the peasants aren't participating in it, that means the country is not fair and the energy use is very inefficient.
(you can see this looking at UK v China - back in the days when the UK had a large manufacturing base in the 60s and 70s, our emissions were still a fraction of what China emits today even though the narrative is that China emits more because we sent our manufacturing industry there)
