China, for ex­am­ple, is the global fron­trun­ner in terms of to­tal emis­sions, ex­ceed­ing that of the US in 2007. But, China is also a rapidly devel­op­ing coun­try with a very high pop­u­la­tion. In mea­sur­ing the emis­sions per in­di­vid­ual, China is ranked 50th in car­bon emis­sions per capita, com­pared to Qatar, ranked first. Here, we show some of the top 50 global emit­ters per capita in the East and West, re­spec­tively. Many peo­ple make the mis­take of con­flat­ing car­bon emis­sions with car­bon diox­ide emis­sions. Cli­mate ex­pert Dr Joe Romm ex­plains the dif­fer­ence: “The frac­tion of car­bon in car­bon diox­ide is the ra­tio of their weights. The atomic weight of car­bon is 12 atomic mass units, while the weight of car­bon diox­ide is 44, be­cause it in­cludes two oxy­gen atoms that each weigh 16. So, to switch from one to the other, use the for­mula: One tonne of car­bon equals 44/12 = 11/3 = 3.67 tonnes of car­bon diox­ide.”
