To develop novel technologies in agriculture which contribute to de-carbonization, we first need to quantitatively evaluate greenhouse gas emissions of conventional agricultural systems as a benchmark for comparisons with advanced systems in the future. Therefore, this study employed a life cycle assessment with an input-output model at the prefectural level and developed a tool for simultaneously evaluating greenhouse gas emissions, energy consumptions and economic ripple effects of conventional agricultural systems, reflecting the structure of regional economy. Case studies demonstrated that this tool could be used to compare the performances of scenarios in which consumptions of various tradable inputs, including fossil fuels and electricity, were changed.
