Given the importance of the cement industry, which is one of the most energy-consuming industries in Thailand with high
associated CO2 emissions, this study attempts to understand the potential for CO2 emissions reduction in this sector and its costs. The bottom-up CO2 abatement cost curve (ACC) constructed in this study for the Thai cement industry to determine the potentials and costs of CO2 abatement by taking into account the costs and CO2 abatement of different technologies. The period of 2010e2025 is chosen as the scenario period for which the abatement potential and costs are assessed. We analyzed 41 CO2 abatement technologies and measures for the cement industry. Using a bottom-up CO2
ACC model, the cost-effective annual CO2 abatement potential for the Thai cement industry over the 15 year scenario period (2010e2025) is equal to 3095 ktonnes CO2/year, which is based on a 10% discount rate. This is about 15% of the Thai cement industry’s total CO2 emissions in 2005. The total technical annual CO2 abatement potential is 3143 ktonnes CO2/year, which is about 15.2% of the Thai cement industry’s total CO2 emissions in 2005
