絶滅危惧種ジンベエザメの重要生息域を避ける航路最適化を、原油タンカーとコンテナ船の8航路でシミュレーションした実証研究。燃料使用量の変化は−0.13%〜9.65%で、大半の長距離航海では1%未満に収まった。短距離は減速、長距離は海域回避が効率的で、動的な種別生息域データの航海計画への統合が、貿易への影響をほぼ伴わない衝突リスク低減と脱炭素目標の両立に寄与しうると示す。
English
A proof-of-concept simulating eight port-to-port voyages for a crude oil tanker and a container ship under baseline, 10-knot speed reduction, and full avoidance of whale shark aggregation sites. Fuel-use changes ranged from −0.13% to 9.65%, with under 1% impact on most long-distance routes. Speed reduction suits short voyages, area avoidance suits longer ones; integrating dynamic species-specific habitat layers into voyage planning could mitigate vessel strikes with negligible trade disruption while aligning biodiversity conservation with maritime decarbonization.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
海運はScope 3排出の主要源であり、邦船社・荷主の脱炭素開示と生物多様性（TNFD）対応が交差する領域。航路最適化が燃料消費と生物多様性保全を両立しうる点は、日本の海運・物流企業のTNFD開示やScope 3算定の実務に示唆を与える。
In the global GX context
Bridges two disclosure streams—shipping decarbonization (Scope 3, IMO climate strategy) and nature-related disclosure under TNFD—showing that biodiversity mitigation need not conflict with fuel/carbon goals. Relevant to global discussions on integrating nature into transition planning and to regulators designing incentive frameworks for sustainable shipping.
👥 読者別の含意

📄 Abstract（原文）
Abstract Vessel strikes are a significant and growing threat to marine megafauna, yet few mitigation measures are implemented at scale owing to perceived economic costs to shipping. Here, we present a proof of concept for integrating biodiversity considerations into commercial voyage optimization, using critical aggregation sites for the endangered whale shark (Rhincodon typus) as a case study. We simulated eight port-to-port voyages for two vessel classes—a crude oil tanker and a container ship—under three routing scenarios: baseline optimization, speed reduction to 10 kts within core habitats and complete avoidance of these areas. Across routes, fuel-use changes ranged from −0.13% to 9.65%, with minimal impacts (less than 1%) for most long-distance voyages. Results indicate that speed reduction is the more efficient mitigation for short voyages, while area avoidance is preferable for longer voyages, with impacts varying by vessel type and operational constraints. Incorporating dynamic, species-specific habitat layers into voyage planning could enable targeted vessel strike mitigation with negligible disruption to global trade. Adoption of such measures, supported by improved data pipelines, dynamic forecasting and integration into regulatory and incentive frameworks, offers a scalable pathway to align biodiversity conservation with decarbonization goals in the maritime sector.
