Ceramic industry is one of high energy intensive industry and major sources of GHG emission. This paper reported the GHG emission of tableware ceramic product in Thailand in the boundaries of “Gate to gate”. The activity data of the tableware ceramic manufacturing had been collected from a small enterprise manufacturing plant and 1 kg of ceramic bowl (8 inches diameter) was chosen as the functional unit of data analysis. The amount of GHG emission in the unit kg CO2 e /kg of product was calculated by the method from IPCC 2006 and the emission factors used in this study were from Thailand Greenhouse Gas Management Organization (TGO). The hotspots of energy consumption and GHG emissions were then identified. The results indicated that the energy consumption per functional unit was 21.816 MJ/kg of product and almost 95.13% of total energy consumption was from liquefied petroleum gas (LPG) consumption during firing. The direct GHG emissions were from LPG used as fuel (47.54%) and from the decomposition of carbonates during firing process (0.26%). While the indirect GHG emission was from the electricity consumption for electrical equipments (52.20%). The total GHG emission based on functional unit was 0.35 kg CO2 e /kg of product.
