The World's Largest Polluters

Maps Mania is a blog dedicated to tracking the very best digital interactive maps on the internet and the tools used to create them.

@mapsmania Per capita is a good way of expressing it, although I would really like to see a map where it is expressed by population density, but inversely. IE if 2 countries have the same population but one has a low density, that implies better carbon practices, because lower population implies less efficiency in general terms (higher logistical requirements for instance).
