Estimating CO2 Emission due to Interregional Trading of Agricultural and Fishery Products for Enviromental Burden Reduction Policies

Supervisor: Kazushi SANO, Satoshi TSUCHIYA, Shoji MATSUMOTO

This study aims at estimating CO2 emission due to transporting agricultural and fishery products, in order to consider about policies for environmentally-friendly regional transportation systems. National freight net flow data is used for the estimation.
The scenario of the first estimation is modal shift induced by speeding up rail and marine cargo. As a result, it is found that 2% of CO2 emission is curtailed.
Secondly, in order to compare the curtailment rate, we find the optimum interregional trade pattern that achieves the minimum CO2 emission, given production volume and consumption demand of each prefecture. Consequently, 39% of CO2 emission is curtailed by minimizing the total distance of conveyance. In addition, considering modal shift to find the above optimum interregional trade pattern, the CO2 curtailment rate goes up to 60%. Although these results are calculated on many assumptions, they could be one significant reference values.
