Outline of Final Research Achievements

In this study, we have developed a model that predicts GHG emissions from shipping, and that forecasts shipping and shipbuilding market in consideration of the effects of environmental regulations. Additionally, we have a developed a system to consider optimal GHG reduction scenarios on maritime transportation sector.
Using proposed model, we quantitatively evaluated the GHG reduction effect for (1) Deceleration operation, (2) Introduction of alternative fuel, (3) Introduction of Energy Efficiency Design Index regulation, and the impact on the shipping and shipbuilding markets by these measures. We also examined a GHG reduction scenario that considers the sustainable development of the shipping and shipbuilding market and the achievement of IMO's GHG emission targets using proposed system.

Academic Significance and Societal Importance of the Research Achievements

これまでの研究はGHG排出削減のみに着目した単眼的な視点での研究が多く，環境規制が海運・造船市場に与える影響の評価に関しては検討されていない．本研究では環境規制が海運・造船市場に与える影響を定量的に評価する新たなモデルを提案した．さらに提案したモデルをベースに，海事産業の持続的発展とGHG削減の双方を考慮した新たなシナリオ立案システムを開発した．
本研究で提案したモデル，システムを活用することで，海事産業の持続的発展を考慮したGHG削減に関する国際ルールの策定支援や技術開発シナリオの立案が期待できる．
