The CO_2 emission in energy conversion sector, mainly, the emissions in industrial and transportation sectors are comparatively large in Japan. One of countermeasure for reducing CO_2 emissions in these sectors would be promotion of BTL fuel. The recycled CO_2 gas which would be generated by CCS process, for instance, may be feedstock of methanol production system. Based on the current R&D level, we propose the MeOH production system due to Bio-H2 sand recycled CO_2 gas of fossil fuel origin, and the low pressurized MeOH synthesis production system. In order to compare their environmental impacts, we analysed the benefit of CO_2 emission reduction on LCA basis. As a result, it implies that the MeOH production system due to recycled CO_2 gas is advantage in comparison to conventional system of fossil fuel origin. Also, on the low pressurized system, the same effect would be obtained, too.
