Abstract
I applied LCA to non-feeding aquaculture and conducted the inventory analysis for scallops, sea tangles and brown sea weeds in this research. As a result, the cumulative CO2 emission per million yen for scallops （ground sowing type）, scallops （hanging type）, sea tangles and brown seaweeds were 848.8, 1,125.0, 1,809.5 and 1,364.4 kg-CO2 /million yen, respectively. Each main generating factor of CO2 emissions was direct fuel consumption. On the other hand, since the large process of fuel consumption differed in each type of industry, it considered the reduction possibility for every type of industry. Moreover, I considered positioning of a type of industry and the validity of an analysis result which were investigated this time by comparing with the I-O analysis result.
