Carbon dioxide emissions are rising around the planet, with China surpassing the United States as the world's leading producer.
According to data recently released by the Department of Energy's Carbon Dioxide Information Analysis Center, China emitted about 1.7 billion metric tons of carbon in 2007 while the U.S. generated nearly 1.6 billion. India was third, emitting 440 million metric tons of carbon into the atmosphere.
Worldwide total CO2 emissions topped 8.3 billion metric tons of carbon for 2007, and 1.25 metric tons of carbon were produced for every person on the planet, according to the CDIAC's June release.
The data show that 20 out of a total of 215 countries together contributed to more than 75 percent of all global CO2 emissions in 2007. This group of 20 is made up of industrialized nations such as the U.S., Japan and Germany, as well as rapidly industrializing nations such as China and India.
When looked at on a per capita basis, the data show the U.S. still among the 20 top producers, while results for more densely populated nations such as China and India are significantly lower.
Use the interactive dashboard below to analyze CO2 emissions data for countries from six continents. The line graph at the top allows for comparison of the per capita CO2 emissions in metric tons of carbon for each of the 20 countries.
Use the interactive stack graph to see how each of the 20 countries measure up:
A cube of CO2 would be nearly 30 feet tall and weigh over 2,000 pounds. As a point of reference, the average height for Americans age 20 and over is about 5' 8" for males and 5' 3" for females, according to a 2008 National Health Statistics report (PDF).
How Big is a Metric Ton of Carbon Dioxide?
For this article, total CO2 emissions are measured in thousands of metric tons of carbon while per capita CO2 emissions are measured in metric tons of carbon. When fossil fuels are burned, carbon oxidizes to produce carbon dioxide or CO2 according to the CDIAC.
To understand the sheer volume of a metric ton of CO2, imagine a giant cube that weighs about 2,200 pounds and is nearly 27 feet tall, 27 feet wide, and 27 feet deep - that's what artists did before the United Nations Climate Change Conference in 2009. According to the CDIAC data, the average American produces more than 19 of these giant carbon dioxide cubes every year.
A Closer Look at Per Capita Emissions
The U.S. was the 11th highest per capita CO2 emitter in the world in 2007, when compared to all of the countries in the CDIAC database. Countries such as China and India, which topped the list for total CO2 emissions, have per capita emissions of 4.95 and 1.43 metric tons of CO2 respectively.
