I think that per-capita normalization in particular is interesting. I have a spreadsheet where I did that, and the Philippines stands out even more then, as does Brazil. GDP is a bad normalization factor here, as the trend is weird. High income countries have very low emissions in general. Low income countries sometimes have high per capita emissions, but not usually. Middle income countries are the most likely to be high emitters, as they are most likely to be consuming large amounts of plastic without having developed the infrastructure to process the waste.
