Abstract
The purpose of this study is to estimate greenhouse gas(GHG) emission efficiency(GEE) and GHG mitigation potential(GMP) of offshore fisheries in preparation for carbon neutral and negative promotion in the ocean and fisheries sector, and to suggest policy improvements related to GHG mitigation. To this end, this study used stochastic frontier analysis(SFA) considering exogenous determinants of GHG emission inefficiency. As a result, the GEE of fleet and drag net fisheries with high fuel cost and vessel age was lower than other fisheries. In addition, the GMP and mitigation ratio of large purse seine, large pair trawl, large otter trawl, and anchovy drag net were higher than those of other fisheries. Lastly, as policy improvements to reduce GHG emission from offshore fisheries, fleet size reduction, development of low-energy used fishing gear, easing of conditions for participation in fishing vessel modernization projects, revising laws to supply eco-friendly fishing vessel, and improvement of the tax-free petroleum supply system were proposed.
