English: This bubble diagram shows the percentage share of global cumulative energy-related carbon dioxide emissions between 1751 and 2012 across different regions (Hansen et al., 2013, p.17):

• Africa 2.6%
• Canada and Australia 3.1%
• USA 28%
• South and Central America 3.9%
• Middle East 3.4%
• China 10.7%
• India 3.0%
• Russia 7.3%
• Germany 6.0%
• UK 5.4%
• Rest of Europe and Eurasia 16.4%
• Japan 4.0%
• Rest of Asia Pacific 4.4%
• Ships and aviation 3.7%

The contribution of emitters to global warming is closely proportional to cumulative emissions (Hansen et al., 2013, p.16). See also: greenhouse gas.

The area and colouring of the circles is proportional to the share of emissions. The radius of the circles equals the square root of (area / π;).
