Characterization of the selected technologies has been carried out in terms of GHG mitigation potential and cost. The selected BETs were assessed for abatement of GHG in Vietnam using LEAP model. The power generation by co-firing is the most cost-effective option although the GHG mitigation potential is low. The substitution of electricity generated from fossil fuel by bagasse in the sugar mills has been found to be attractive. Rice husk based power generation is also a cost-effective option. The wood based BIGCC power plants are no-regret options when substituting the power generation by coal and oil based power plants. WTE is another teclmology, which is attractive for substituting coal and oil based power plants. The electricity generation by Stirling engines is expensive but these engines can be used for decentralized power generation. Replacement of traditional LPG stoves by has been found to be is a noregret option. The study also involved estimation of GHG abatement cost of different biomass energy teclmologies in Vietnam. GHG mitigation options considered included replacement of coal stoves by biomass stoves, replacement of LPG and kerosene stoves by biogas stoves, substitution of gasoline by ethanol in cars, substitution of coal by wood in industrial boilers and the substitution of the fossil fuel power generation by biomass based power generation. Abatement cost of these options lie in the range of - 21.21 to 94.40 US Dollars (1995) I thousand kilograms of C02 abated.10aBiomass energyxClimatic factors10aGreenhouse gas mitigation1 aBhattacharya, Sribas C.,eChairperson1 aPham, H.L.,eExamination Committee1 aKumar, Sivanappan,eExamination Committee1 aShrestha, Ram M.,eExamination Committee2 aH.M.
