Comment on China's green energy boom could spell the end of the fossil fuel age
Skua@kbin.earth 1 day agoNational emissions should be approached per capita. It'd be silly to expect that Luxembourg and France should have the same total emissions

Per capita emissions favour densly packed high population countries.
I dont think countries thay have 5m people should be held to the same number as ones that have 1billion. For nz the best way for us to reduce our per capita emissions is to add another 50m people but that would be counter productive since we want to reduce overall pollution.

Do you have actual data for that? Here are some comparisons of population density and emissions per capita:
The first image is every country and territory that wikipedia had numbers for on both population density and emissions per capita.
The second has outliers with the highest densities and emissions per capita removed in order to make the rest visible (removed entries are Bahrain, Bangladesh, Barbados, Bermuda, Brunei, Gibraltar, Hong Kong, Kuwait, Macau, Maldives, Moldova, New Caledonia, Palau, Qatar, and Singapore. I hope you agree that these are not particularly comparable to the US or China for a variety of reasons and are okay to exclude).
The third cuts it down to only countries that have a "very high" rating (at least 0.8) on the Human Development Index, as a proxy for advanced economies. As you can see, there is not a strong correlation between high densities and low emissions. Chile, Sweden, Argentina, and Norway all actually have both significantly lower densities than the US and significantly lower emissions (and there are more, I'm just counting some with populations of at least ten million). Same goes for NZ, there are several countries with comparable or lower densities and also lower emissions. The densest countries are not particularly low emitters, and the sparsest cover the full range.
I can think of a few potential factors explaining it. Yes, high density makes transport easier, but it also means less access to land for clean energy (which is generally much less compact than fossil fuels). Additionally, even in very sparsely-populated countries, most of the population actually tends to be fairly concentrated around a few cities anyway. Consider Australia; it's not like Australians are evenly distributed across the continent, so the very low population density isn't particularly representative of the infrastructure challenges for most people there
