日本語

本論文は、ライフサイクル評価（LCA）と専門家意見聴取を組み合わせた港湾脱炭素化の手法を提案し、ポルトガルのシネス港に適用した。LCAの結果、スコープ3排出量が総排出量の99％以上を占め、外航船が主な排出源であることが判明した。一方、専門家はエネルギー関連対策を優先したが、スコープ3への対応が不十分であり、戦略のミスマッチが明らかになった。この統合アプローチにより、港湾は高影響の対策に戦略をシフトできる。

English

This paper proposes an integrated method combining Life-Cycle Assessment (LCA) and expert elicitation for port decarbonization, applied to Portugal's Port of Sines. LCA reveals Scope 3 emissions account for over 99% of total GHG emissions, mainly from ocean-going vessels. However, experts prioritized energy-related measures (Scope 1/2), indicating a misalignment. The approach helps ports realign strategies toward high-impact Scope 3 measures and offers transferable insights for other ports. (358 chars)

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本の港湾（横浜港、神戸港など）でもスコープ3排出が支配的である可能性が高く、SSBJやISSBに基づく開示が進む中、本論文の手法は実践的な示唆を与える。港湾管理者は自施設の排出構造をLCAで可視化し、専門家意見と組み合わせることで、効果的な脱炭素戦略を策定できる。

In the global GX context

This paper is highly relevant for global port decarbonization, especially under ISSB and CSRD frameworks requiring Scope 3 disclosure. It demonstrates a reproducible method combining LCA and stakeholder input, revealing the critical gap between actual emission sources and commonly prioritized measures. Port authorities worldwide can use this approach to align strategies with high-impact Scope 3 interventions.

👥 読者別の含意

🔬研究者:The paper provides a novel methodological framework integrating LCA and expert elicitation for port decarbonization, useful for transport systems researchers.

🏢実務担当者:Port sustainability teams can apply the combined LCA and expert elicitation approach to identify high-impact decarbonization measures beyond direct control.

🏛政策担当者:Regulators should consider mandating Scope 3 emission reporting for ports and aligning policy incentives with indirect emission sources.

📄 Abstract（原文）

Port decarbonization strategies often prioritize emissions under direct port authority control while overlooking dominant indirect sources. This study proposes an approach that combines Life-Cycle Assessment (LCA) and expert elicitation. While existing studies often rely on descriptive emission inventories, this paper demonstrates the value of combining quantitative life-cycle data with expert judgment. The methodology is applied to the Port of Sines, Portugal’s largest port by cargo volume and handling capacity. The LCA revealed that Scope 3 emissions account for over 99% of total greenhouse gas emissions, with ocean-going vessels as the main contributors. The expert elicitation process prioritized energy-related measures such as renewable energy, alternative fuels, electrification, and energy efficiency, while onshore power supply and ship–port interface measures received lower priority. By comparing the results, the study reveals a misalignment between the most significant emission sources (Scope 3 emissions, particularly ocean-going vessels) and commonly prioritized decarbonization measures (measures addressing Scopes 1 and 2). The main contribution lies in combining LCA findings and expert inputs to actively inform strategic decision making, helping ports realign decarbonization strategies toward high-impact measures and providing transferable insights for other ports pursuing net-zero objectives.
