Emissions from biomass energy use in some selected Asian countries

In this paper, an attempt has been made to estimate the annual emission of certain greenhouse and other gases and substances from biomass energy sources in selected countries of Asia. For this purpose, the reported values of the different emission factor for biomass combustion have been compiled from an extensive literature review. From the compiled values, a set of emission factors of different gases/pollutants for each fuel-combustion system combination is obtained for each country. The emission factors for the carbon containing gases, i.e. CO2, CO and CH4, are corrected by multiplying each emission factor by a correction factor to avoid over- or under-estimation of total carbon emission. Estimated biomass energy use by technology and the corrected emission factors are used to estimate the total emissions in the selected countries.
