With the total charcoal production per year of 2495.30 ton (equivalent to 57.58 TJ/year), and from the energy value of LPG of 50.0 kJ/gram LPG, and the emission factor for LPG of 63.1 ton CO2/TJ (IPCC, 2006), it was estimated that emissions of about 3,633 tons CO2 per year could be avoided. However, there are some uncertainties associated with this calculation. Firstly, CO2 emissions from fossil fuel use, such as during wood transport, land preparation, and charcoal transport to the users are not accounted for. Also, certain greenhouse gases such as N2O and CH4 may be also produced during the pyrolysis phase of charcoal production. If these are included, the amount of CO2 emissions avoided could be reduced. Despite this, the results of this study reveal that forest management through repeated planting and harvesting for charcoal production do contribute to reducing greenhouse gas emissions. In addition, significate amounts of carbon can be stored in the soil and in other parts of the biomass, for about 12 years during the growth of mangrove trees.
