Abstract
The purpose of this study is to estimate potential greenhouse gas(GHG) reductions of offshore fisheries following the implementation of 「2050 Carbon Neutral」 strategy and then to suggest policy alternatives based on the analysis results. To estimate the potential GHG reductions, a dynamic optimal fisheries theory was used in the analysis. As a result, the offshore fisheries" fishing effort was inputted 30% more than the optimal level. If excess fishing effort were reduced, the potential GHG reductions of offshore fisheries was estimated to 464,683tCO₂. In addition, when GHG emissions are regulated, the profit rate of offshore fisheries decreases by 0.46%, but it is analyzed that there is no significant damage. Thus, in order to reduce GHG emissions, it is necessary to expand fishing vessel buyback program and start discussion on the development of electric hybrid fishing vessels.
