Abstract: Waste disposal is one of the sources of greenhouse gas emissions from urban human activities． According to the Guidelines for National Greenhouse Gas Inventories，based on collected activity data from Xinjiang related statistics in 2010， the greenhouse gas emissions from waste disposal were estimated． The results showed that the total CO2 ( CO2 equivalent) emissions from waste disposal in Xinjiang were 3 570 230. 74 t in 2010． The largest greenhouse gas contributor from the solid waste landfill was about 2 744 006. 79 t; the least greenhouse gas contributor from the solid waste incineration was only about 179. 67 t，CO2 emissions from waste water treatment reached 826 044. 28 t． The results was the basis for carbon emission reduction in Xinjiang，providing some references to relevant researches of the other provinces．
