Estimation of greenhouse gas mitigation potential from carbon intensity and energy data analysis from Thai industrial sector

Abstract Industrial sector is one of the highest energy consumption and greenhouse gas (GHG) emission in Thailand. There are around 6,000 designated factories which consume large amount of energy and emit vast GHG volume each year. In this study, we investigate and validate the energy consumption and efficiency data from Thailand’s designated factory database and converted into GHG value. With the assumption of the top 80% of GHG emission threshold to be considered, it can be concluded that there are only up to 7% of number of designated factories but emitted at around 80% of total emission from designated factory of the country. In the context of GHG emission reduction potential estimation, the carbon intensity difference concept have been applied to the factories over the threshold. The results show that when compare with Best carbon intensity scenario, Thailand will reduce around 29 MtCO 2 or 31% of the GHG emission emitted in 2018 in industrial sector, while the figure would be 15 MtCO2 reduction potential or 16% for the Average Carbon Intensity scenario.
