This paper used some calculation techniques of IPCC to quantify the economic and environmental benefit from greenhouse gas (GHG) emission mitigation at Van Cu rice noodle craft village, Huong Toan commune, Huong Tra town, Thua Thien Hue province. | Vietnam Journal of Science and Technology 55 (4C) (2017) 1-7 ASSESSMENT OF EFFECTIVENESS TO REDUCE GREENHOUSE GAS EMISSION OF BIOGAS DIGESTERS IN LIVESTOCK MANURE TREATMENT AT VAN CU RICE NOODLE CRAFT VILLAGE, THUA THIEN HUE PROVINCE Tran Thi Tu*, Nguyen Dang Hai Institute of Resources and Environment- Hue University, 07 Ha Noi street, Hue city, Thua Thien Hue province, Viet Nam * Email: tttu@ Received: 30 June 2017; Accepted for publication: 14 October 2017 ABSTRACT This paper used some calculation techniques of IPCC to quantify the economic and environmental benefit from greenhouse gas (GHG) emission mitigation at Van Cu rice noodle craft village, Huong Toan commune, Huong Tra town, Thua Thien Hue province. The resulting calculation showed that the GHG emission amount of Van Cu rice noodle craft village was 1, tonnes of CO2e/ year, in which the GHG emission of households who had activities of swine breeding and rice noodle producing had accounted for 78% of total emissions of the whole village. There were 24 biogas digesters in 31 households had built biogas works that were working well and creating biogas for usage as fuel to service of life. Therefore, this study surveyed at 24 households were using biogas works efficiency. Before using biogas works, average GHG emission reached tonnes CO2e/ household/ year. After using biogas digesters, total GHG emission of 24 households reduced tonnes of CO2e/ year. Thus, the total GHG emission amount was cut down tonnes of CO2e/ year, corresponding to revenue from the sale of certified emission reductions (CERs) was million dong/ year. Keywords: biogas, certified emission reductions (CERs), emission, Van Cu rice noodle craft village. 1. INTRODUCTION Van Cu rice noodle craft village had 162 households that joined in rice noodle production with 20,330 kg/day in 2016. Wastewater from rice noodle production was m3/day. Furthermore, community at this village had recycled .
