Emissions by Country with Global Average - dashed line

The areas of the wedges, and the numbers beside the country/region name, represent total CO2e emissions, in Megatonnes(Mt)/year reported for 2006. The angle of the wedge represents the total population (2007 figures). The radius represents the percapita emissions.

The wedges are arranged by per-capita CO2 emissions.

The emissions numbers are from the Energy Information Administration figures and the population numbers are from the Population Reference Bureau.

Notes:

• Total emissions for China are slightly less than the US even though their population is more than 4 times as great (China: 1,318 million. US: 302 million).
• Canada's 2006 percapita emissions are the second highest (behind the US). More recent estimates put Canada at the top of the list.
  
• The grey circle represents average global emissions  for the year 2000.
