Abstract: Based on the data from Annual Statistical Report on Environment in China and methods recommend by IPCC, greenhouse gas (GHG) emissions from domestic wastewater and industrial wastewater in China from 2003 to 2009 were estimated, and emission characteristics were analyzed. GHG emissions per capita from wastewater treatment were also analyzed. The results show that the GHG emissions from wastewater treatment increased continuously from 2003 to 2009, the N2O emission from domestic wastewater was the major source of the GHG emissions from wastewater and the CH4 emissions from domestic wastewater increased fastest. The CH4 emission from manufacture of paper was the major emission source from the wastewater of the five industrial sectors. GHG emissions from the wastwater treatment per capita increased continuously from 2003 to 2009.
