> Pretty sure. Nature, being unconcerned with fairness, has little regard for per capita statistics.

But nature also has little regard for per country statistics. Splitting China into two countries, isn't going to lower their polution.

Using per capita statistics at least allows us to focus on those that are emitting excessively more than others.

Splitting a country is not going to lower the pollution, but equally so does a high populations density not decrease pollution.
