Nov 25 (Reuters) - Following is a table showing the world's top 25 emitters of greenhouse gases. About 190 nations will meet from Dec. 1-12 in Poznan, Poland, to work on a new treaty to combat climate change.

The ranking itself is based on greenhouse gas emissions in 2000, the latest year of comparable data, in millions of tonnes (mT) of carbon dioxide equivalent (CO2e). China may have overtaken the United States in 2007 as top emitter, analysts say.

Also listed are the emissions in 1990 and 2006 of greenhouse gases by industrialised countries. The U.N.'s Kyoto Protocol requires rich nations to submit such data under obligations to cap greenhouse gases from 2008-12 compared to a 1990 baseline.
