海運は世界貿易の約80%を担うが、CO2排出の主要源でもある。本論文はLNG・メタノール・アンモニア・水素などの代替燃料、省エネ・運航改善、国際規制を質的に検討し、単一解では完全脱炭素は不可能で、燃料革新・技術・運航最適化の組合せが必要と結論づける。インフラ・安全・経済性が普及の制約であり、規制が移行を加速する鍵となる。
English
Maritime transport carries ~80% of global trade but is a major CO2 emitter. This qualitative review examines alternative fuels (LNG, methanol, ammonia, hydrogen), efficiency measures, and international regulation, concluding no single solution achieves full decarbonization—a combination of fuel innovation, technology, and operational optimization is required. Infrastructure, safety, and cost constraints limit adoption, while regulation is critical to accelerating the transition.

日本のGX文脈において
海運は日本の貿易・自動車・造船産業と直結し、IMO規制や燃料供給インフラ整備は国内GX政策・企業戦略に影響する。Scope 3排出の主要カテゴリとして荷主企業の開示対応にも示唆を与える。
In the global GX context
Aligns with IMO 2023 GHG strategy and global transition-finance debates on shipping decarbonization. Relevant to Scope 3 accounting for shippers and to ISSB/CSRD disclosure of transport emissions, though it offers limited novel empirical evidence.

📄 Abstract（原文）
Abstract Maritime transport is a fundamental component of global trade, ensuring the movement of approximately 80% of goods worldwide. Despite its efficiency, the sector remains a notable contributor to greenhouse gas emissions, particularly carbon dioxide (CO 2 ). In the context of increasing environmental concerns and international pressure to reduce emissions, decarbonization has become a strategic priority. This paper aims to examine the main pathways through which maritime transport can transition towards zero-emission operations. The study adopts a qualitative approach based on the analysis of recent industry reports, regulatory frameworks, and existing literature. It focuses on evaluating technological solutions, including alternative fuels such as liquified natural gas (LNG), methanol, ammonia and hydrogen, as well as energy-efficiency measures and operational improvements. Particular attention is given to international regulations and their role in shaping industry practices. The analysis indicates that no single solution can achieve full decarbonization independently. Instead, a combination of fuel innovation, technological advancement, and operational optimisation is required. While alternative fuels show significant potential, their widespread adoption is currently limited by infrastructure constraints, safety considerations, and economic factors. Regulatory measures are found to play a critical role in accelerating this transition. In conclusion, the decarbonization of maritime transport represents a complex but necessary transformation. Achieving zero emissions will depend on coordinated efforts between policymakers, industry stakeholders and technology developers. The findings of this paper contribute to a better understanding of current challenges and highlight practical pathways for a more sustainable maritime future.
