Abstract: According to the calculation methods of certified emission reductions under the clean development mechanism of Kyoto Protocol, this study investigated the greenhouse gas (GHG) emission reductions under afforestation and reforestation projects in Karamay. We set up 2 fixed-point plots and 48 random plots inside the artificial forest; one fixed-point plot and 4 random plots outside the artificial forestry under a desert environment. Carbon storages of the artificial forest and the desert were calculated as well as the GHG emission and leakage of the artificial forest. The net GHG emission of the projects was calculated accordingly. The results showed that the GHG emission reductions was 432 751.59 t of CO2 from the afforestation and reforestation projects in Karamay since 2001 to 2009 with an average annual emission reduction of 54 093.95 t of CO2 over the period. The effect of the emission reductions was significant from the projects which indicated that it was feasible to adopt the afforestation and reforestation projects to reduce GHG emission in arid areas. The results of the study provided fundamental information for the development and the management of the projects.
