In Thailand, the percentage of energy consumption and greenhouse gas (GHG) emissions in freight transportation sectors keep growing rapidly in the opposite side of GHG reduction target. The objective of this study is to evaluate the impacts on socio-economic status and GHG emissions in Thailand when introducing new greenhouse gas mitigation options in freight transportation sectors according to Thailand National Master Plan. This research constructed the country level dynamic multi-sector computable general equilibrium (CGE) model replicating the input-output table of Thailand in 2010 as a benchmark data. In this analysis the 3 scenarios have been assessed by CGE model. BaU represents the reference scenario that does not limit total GHG emissions. Using Thailand’s Nationally Determined Contribution (NDC) plan as mitigation target, NDC is the scenario that limits total GHG emissions in 2030 to 20 % lower than BaU scenario. Then this study introduces mitigation options (S_all scenario) to freight transport sectors including road sector, rail sector and water sector under NDC mitigation target to assess the impact of new mitigation options on economic indicators and GHG emissions. As a result, NDC scenario showed that GDP and consumption in 2030 will drop by 2.1 % and 3.5 % respectively compared with those in BaU. Introducing mitigation options in freight transport sectors contributed to lower GDP loss and consumption loss by 1.04 % and 0.9 % respectively compared to NDC. It is also found that under GHG emissions limitation, GHG price will become effective and it will increase the cost of energy intensive goods in both industry and household sectors. Thailand economy may suffer loss from this reduction of energy intensive production; however, introduction of mitigation options in freight transport sectors will help compensate the production loss through the increase of production activities in low carbon energy intensive sectors.

在泰国，与温室气体减排目标相反的是，货运部门的能源消耗和温室气体排放百分比持续快速增长。这项研究的目的是，根据泰国国家总体规划，在货运部门引入新的温室气体减排方案时，评估对泰国社会经济地位和温室气体排放的影响。本研究构建了国家级动态多部门可计算一般均衡（CGE）模型，该模型复制了2010年泰国的投入产出表作为基准数据。在此分析中，通过CGE模型评估了3种情况。BaU代表了不限制温室气体总排放量的参考情景。使用泰国的国家自主贡献计划（NDC）作为缓解目标，NDC是将2030年的温室气体总排放量限制为比BaU情景低20％的情景。然后，本研究向NDC缓解目标下的公路，铁路和水务等货运部门介绍了缓解方案（S_all情景），以评估新的缓解方案对经济指标和温室气体排放的影响。结果，NDC情景显示，与BaU相比，2030年GDP和消费量将分别下降2.1％和3.5％。与NDC相比，在货运部门引入缓解措施使GDP损失和消费损失分别降低了1.04％和0.9％。还发现，在温室气体排放限制下，温室气体价格将变得有效，并且将增加工业和家庭部门能源密集型产品的成本。能源密集型生产的减少可能会给泰国经济带来损失；但是，在货运部门采用缓解措施将通过增加低碳能源密集型行业的生产活动来弥补生产损失。
