本研究は、AISデータを用いたボトムアップフレームワークを開発し、上海–ロサンゼルス/ロングビーチグリーンシッピング回廊におけるCO2排出量とコンプライアンスコストを推定した。IMO CIIおよびGFI要件のもと、HFO、LNG、バイオ燃料、アンモニア、メタノールなどの代替燃料と炭素回収技術を組み合わせて分析。結果、2035年以前はCII要件がGFI要件をカバーし、炭素回収なしでは化石LNGとバイオLNGの併用が有利、炭素回収ありではLNG+CCSとHFO+CCSが有望と示された。
English
This study develops an AIS-based bottom-up framework to estimate carbon emissions and compliance costs in the Shanghai–Los Angeles/Long Beach green shipping corridor. It evaluates eight alternative energy options and carbon capture technology under IMO CII and GFI requirements. Results show that before 2035, CII covers GFI, and without carbon capture, fossil LNG + bio-LNG is favorable; with carbon capture, LNG + CCS and HFO + CCS emerge as advantageous pathways.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本フレームワークは日本の海運会社が国際航路の脱炭素戦略を策定する際に参考となる。特に、CIIとGFIの二重規制への対応策として、LNGと炭素回収の段階的導入を示唆しており、SSBJ/有報におけるGHG開示にも関連する可能性がある。
In the global GX context
This framework provides a replicable methodology for assessing decarbonization pathways in any shipping corridor, contributing to global maritime emission reduction efforts. It highlights the interplay between CII and GFI regulations and the role of carbon capture as a transitional technology, relevant for IMO policy development and corporate strategy.
👥 読者別の含意
🔬研究者:Researchers can adopt the AIS-based bottom-up approach to evaluate alternative fuels and carbon capture in specific corridors.
🏢実務担当者:Shipping companies can use the findings to plan phased transitions from fossil LNG to bio-LNG and carbon capture for compliance.
🏛政策担当者:Policymakers can consider the interaction between CII and GFI and the potential of carbon capture in shaping future regulations.
📄 Abstract(原文)
Green shipping corridors have become a key strategic initiative for advancing maritime decarbonization. This study develops an AIS-based bottom–up framework for estimating carbon emissions and compliance costs in green shipping corridors. The framework combines corridor fleet identification, AIS-based energy consumption and emission estimation, and compliance-cost modeling under the IMO CII and GFI requirements. On this basis, eight alternative energy options—HFO, fossil LNG, bio-LNG, e-LNG, bio-methanol, e-methanol, green ammonia, and biofuel B100—together with carbon capture technology, are incorporated into the analysis and applied to the Shanghai–Los Angeles/Long Beach green shipping corridor. The results show that before 2035, the emission reduction requirements of CII can cover the basic compliance requirements of GFI. Without carbon capture, the combined use of fossil LNG and bio-LNG appears to be a relatively favorable transition pathway. When carbon capture is considered, LNG with carbon capture and HFO with carbon capture emerge as two relatively advantageous transition pathways. During 2025–2035, it is recommended that ships first adopt fossil LNG, then gradually introduce limited amounts of bio-LNG, and subsequently integrate carbon capture once the technology becomes mature.
