日本語

本研究は、鉄道と低排出ラストマイル配送（電気自動車、カーゴバイク、クラウドシッピング）を組み合わせた都市物流システムを提案し、経済的評価を行う。シミュレーションと損益分岐分析を用い、カーボンプライシングが道路輸送コストを増加させる一方、鉄道統合モデルは安定していることを示した。40%のモーダルシフトで月間排出量を約25%削減でき、鉄道＋自転車システムが最もコスト効率が高い。

English

This study proposes and evaluates an urban logistics system combining rail transport with low-emission last-mile delivery modes (electric vehicles, cargo bikes, crowdshipping). Using operational simulation and break-even analysis, it finds that carbon pricing significantly increases road transport costs while rail-integrated models remain stable. A 40% modal shift from road to rail reduces monthly freight emissions by about 25%. The rail-bike configuration is the most cost-effective under an emissions trading system.

日本のGX文脈において

欧州の事例に基づくが、カーボンプライシング下での鉄道シフトの経済評価は、日本の都市物流の脱炭素化政策（GX実現に向けた物流効率化）にも重要な示唆を与える。特に、炭素価格が高まる中での鉄道＋電動アシスト自転車の経済優位性は、日本の都市部での導入可能性を検討する上で参考となる。

In the global GX context

This study directly addresses the EU's climate goals by evaluating rail-integrated urban logistics under carbon pricing. It provides empirical evidence for policymakers and practitioners on how modal shift combined with low-emission last-mile delivery can reduce emissions cost-effectively. The findings are relevant to global cities pursuing sustainable freight solutions and highlight the strategic value of multimodal systems in the context of rising carbon prices.

📄 Abstract（原文）

The European Union has set ambitious climate goals as part of its commitment to the Paris Agreement and the European Green Deal. Urban freight transport is one of the main sources of greenhouse gas emissions, air pollution, and traffic congestion, which is a major hurdle for sustainable urban development. Despite significant policy and research interest, there are currently limited published studies that fully combine rail freight transport with low/zero-emission last-mile delivery and its comprehensive economic evaluation. This study presents and evaluates a comprehensive solution combining rail transport of inter-regional shipments with logistics micro-hubs located near the railway station and transshipping shipments through environmentally friendly last-mile delivery modes such as electric vehicles, cargo bikes, or crowdshipping. The methodology consists of applying several methods, such as operational simulation and break-even analysis, to assess the economic viability of the proposed solution, through different scenarios for the evolution of the regulatory framework (in particular, transport emission allowances). The findings indicate that carbon pricing significantly increases the cost of road regional deliveries by Heavy Goods Vehicle, while rail-integrated models demonstrate relative stability. A modal shift of 40% from road to rail reduced monthly freight emissions by approximately 25%, primarily by eliminating long-distance Heavy Goods Vehicle trips with a low-carbon rail section. Moreover, the combined rail–bike system offered the most cost-efficient and environmentally robust configuration under emission trading system conditions, reinforcing the strategic value of multimodal urban freight systems. The research provides evidence-based insights for policymakers, logistics operators, and urban planners, highlighting the role of rail-integrated, multimodal systems in shaping sustainable and resilient urban freight networks.
