Australia's daily per-capita carbon dioxide (CO2) emission. Illustration comparing Australia with the European Union (EU), China and the whole world in terms of actual amounts of greenhouse gases emitted per day as measured in the equivalent (e) volume of CO2 gas. The volumes are labelled with the CO2 weight in kilograms, with the human figures providing a scale. Australia, with a relatively small population, has a very large per-capita CO2-equivalent emission figure of 73 kilograms compared to the EU (27 kilograms), China (21 kilograms) and the whole world (18 kilograms). Data from the CAIT 2.0 climate data explorer (2013).
