> Global warming does not care about 'fairness', global warming cares about co2 PPM in the atmosphere. When we address climate change, we have to do so at the government level, or we mine as well not bother.

That is why per capita is the correct measure.

The atmosphere is very good at mixing CO2 so a given amount of emissions anywhere has the same impact anywhere as the same amount of emissions from anywhere else.

Whatever we decide the limit on atmospheric CO2 needs to be to address warming needs to be converted into a quota for each country, since enforcement has to be done at the country level.

We can't just take the total and divide it by the number of countries. That would mean that Vatican City would have the same quota as the US. Regionally it would mean that the EU would have 27 times the quota of the US.

The only sensible initial allocation is to divide the total allowed by the world population, and assign each individuals share to whatever country has the power to regulate them.
