the guardian has taken the latest Energy Information Administration figures (covering 2006) and put them in a nifty carbon atlas (a very cool graphic).
a brief explanation of the figures is given by duncan clark. the bottom line: global co2 emissions went up by 2.4 per cent in 2006, to 29,195m tonnes. china overtook the united states as the top emitter, producing 6018m tonnes. it's per capita production is only 4.6, while the united states' is 19.8.
hong kong is ranked 43, producing 85m tonnes, with 12.1 per capita. that's pretty high..
