บทคัดย่อ (EN): This study presents the life cycle greenhouse gas balance from biodiesel production in Thailand, including the evaluation ofthe effects of land-use change, which result from biodiesel promotion policies. Thailand is now cultivating oil palm in different parts of the country which leads to different balances in biodiesel life cycle due to different farming practices, variable yields, and transportation needs. To evaluate the GHG balance from three chosen land use change scenarios: rubber plantation to oil palm plantation in Krabi, cassava plantation to oil palm plantation in Chonburi, and abandoned land to oil palm plantation in Pathumthani, Life Cycle Assessment was used as the tool. The study was focused upon showing the GHG balance from biodiesel production, since the life cycle in this study starts from oil palm plantation and ends at biodiesel production plants. Transportation of fresh fruit bunch (FFB) and crude palm oil (CPO) were also included. The functional unit is 1 million liters of biodiesel production per day. The life cycle GHG balance from the study shows that, for l functional unit, biodiesel produced from Krabi case totaled -711.36 Mg CO2-eq/day, and from Chonburi case and Pathumthani case -750.64 Mg CO2-eq/day and -604.03 Mg CO2eq/ day, respectively. Pathumthani case showed the least minus GHG balance, even with the least fertilization applied, partly because the plantation is far from the mill and biodieseI plant, so more GHG was emitted from the transportation section while Chonburi case showed the highest minus GHG balance due to the fact that it would require more land to grow oil palm to meet functional unit, resulting in more soil carbon being sequestered. However, the land use change scenarios chosen for this study all show negative GHG balances which means the conversions of land cover, as assumed for this study, help reducing GHG in the atmosphere. The estimation of soil carbon change from other land use to oil palm plantation is resulted in an increase in soil carbon ranging from 1.24 - 1.90 Mg C per hectare per year, which is equal to about 4.55 - 6.97 Mg CO2-eq per hectare per year of CO2 removal.
