 ::::Agreed. There is no scientific discussion as far as I know about why this should matter, but there is also no scientific discussion on why per capita rating is better or more relevant than by nation. This is not so much a scientific debate as one of interpreting statistics, and as such there is no 'right' way to analyze the numbers we see on emissions. Being as both analysis have political consequences, the best way to maintain neutrality is to represent both points of view. Sort of like how when the US government formed there was disagreement on how states would be represented in Congress, resulting in both the Senate (by state) and the House (by population): neither solution could have stood on its own. ~ | "
