World CO2 emissions from energy use

 Global emissions of carbon dioxide have risen by 88% since 1971 and are projected to rise by another 52% by 2030. In 1971, the current OECD countries were responsible for 66% of the total. As a consequence of rapidly increasing emissions in the developing world, the OECD contributed 49% to the total in 2004, but this is expected to fall to 38% by 2030. By far, the largest increases in non-OECD countries occurred in Asia, where emissions in China have risen by 5.5% per annum between 1971 and 2004. The use of coal in China increased levels of CO2 by 3.2 billion tons over the 33-year period. Two significant downturns can be seen in OECD CO2 emissions, following the oil shocks of the mid-1970s and early 1980s. Emissions from the economies in transition declined over the last decade, helping to offset the OECD increases between 1990 and the present. However,
