How Much Carbon Dioxide?

How much CO₂ does your economy emit?

Everybody knows that the United States is the World Leader in CO₂ emissions. We are responsible for about a quarter of the whole world's annual CO₂ emissions from burning fossil fuels. (The top 11 producers [including the EU15 as one] account for about 80% of world emissions.)

But there are other ways of measuring a nation's impact on atmospheric CO₂. For example "carbon intensity" is the metric tons of CO₂ emitted divided by GDP. The carbon intensity of the U.S. is about half a ton of CO₂ per $1000 of GDP (measured in 2000 dollars). Some of the top 11 have higher intensity (China, Russia, South Korea, Iran and Australia) and some have lower (Japan and India are the lowest at about a third of a ton per $1000 GDP, converting their currencies at purchasing power parity.)

Or we might compare carbon dioxide emissions per capita. This puts the U.S. back on top, together with Australia and Canada at about 20 metric tons of CO₂ per person per year. Japan and Europe produce half as much per person, China 3.6 tons per person, and India only one ton.

These per-capita comparisons are shown graphically above, and here.

Most of these figures were found at the U.S. Energy Information Administration site. The map at Nationmaster is based on data maintained by the World Resources Institute.
