日本語

本研究は、海運業の技術的・運用的脱炭素戦略がGHGと大気汚染物質に与える相乗効果を定量評価する枠組みを提示する。ブラックカーボンをCO2eq評価に統合し、EU ETSやIMOの規制動向に整合させた。AISデータと負荷依存型排出係数を用いた5船種の分析により、代替燃料と船上CCSが深い脱炭素化と大気汚染削減に最も有効であることを示した。

English

This study presents a quantitative framework evaluating the synergistic effects of technical and operational decarbonization strategies in shipping. It integrates black carbon into CO2eq assessment, aligning with EU ETS and IMO trends, and uses AIS data with load-dependent emission factors across five vessel categories. Alternative fuels and onboard CCS prove most effective for deep decarbonization and air pollutant reduction.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

海運は日本にとって貿易・物流の要であり、IMO規制やEU ETS対応は日本船社・港湾の競争力に直結する。本論文の二重指標（炭素税と外部費用）は、国内のカーボンプライシング議論や海運脱炭素投資の政策設計に示唆を与える。

In the global GX context

This paper bridges global climate objectives with local public health by reconciling carbon taxes and external costs, offering a dual-metric approach relevant to IMO and EU ETS implementation. It adds empirical evidence on vessel-category-specific decarbonization efficacy, useful for international maritime disclosure and transition finance discussions.

📄 Abstract（原文）

Transportation emits greenhouse gases (GHGs) and various air pollutants detrimental to human health. To achieve net-zero GHG emissions by 2050, the maritime industry has implemented increasingly stringent regulations and commitments. Consequently, substantial investments in modern technologies, alternative fuels, and innovative operating methods are being aligned with these new emission standards. This article presents a comprehensive quantitative framework to evaluate the synergistic effects of technical and operational decarbonization strategies. Unlike previous studies, this research integrates black carbon as a critical climate-forcing agent into the CO2eq assessment, aligning with emerging regulatory trends within the EU ETS and IMO frameworks. Furthermore, it establishes a dual-metric evaluation of maritime sustainability by reconciling global climate objectives with local public health impacts through a synchronized analysis of Carbon Taxes and External Costs. The study utilizes a novel load-dependent emission factor set and automatic identification System (AIS) datasets for five ship categories. The findings indicate that while operational methods reduce emissions moderately, transitioning to alternative fuels and implementing onboard carbon capture and storage (ccS) systems are significantly more effective in achieving deep decarbonization and mitigating air pollutants. These results provide detailed insights into the efficacy of various methods in reducing external costs and serve as a valuable reference for regulatory and management agencies.
