本論文は、自転車インフラの温室効果ガス（GHG）削減効果に関する既存研究を体系的にレビューした。17件の研究を分析し、自転車は運行時排出の削減に大きく寄与するが、インフラ建設や維持に伴う排出が効果を相殺する可能性があることを示した。モードシフト分析が主要手法であり、大規模インフラ整備におけるGHG削減ポテンシャルを明らかにしている。
English
This paper systematically reviews 17 studies on the GHG mitigation benefits of cycling infrastructure. It finds that cycling significantly reduces operational emissions, but embodied emissions from infrastructure installation and maintenance can negate some benefits. Mode shift analysis is the dominant approach, highlighting the potential of large-scale cycling infrastructure for urban decarbonization.

📄 Abstract（原文）
Cycling is widely recognized as a sustainable urban mobility solution, and many municipalities focus on cycling infrastructure expansion to promote improved environmental sustainability. However, the current literature on cycling has predominantly focused on safety and health benefits, while the environmental benefits including GHG mitigation benefits remain less explored. To summarize findings from the current literature that explore the GHG emissions-related benefits (or costs) of cycling infrastructure, we conducted a literature review using five major scientific databases, following the PRISMA guidelines. Out of 824 screened records, 17 studies met the inclusion criteria. Most studies were published in the last decade, reflecting a limited but growing interest in this topic. The current analytical approaches include mode shift analysis, life cycle assessment, and scenario modelling. Among these, mode shift analysis (i.e., assessing the potential benefits related to replacement of car trips with cycling) remains a commonly used method. We found that cycling offers significant operational benefits by reducing GHG emissions, especially in the context of large-scale expansions of cycling infrastructure. Existing research indicates that even when embodied emissions are considered, bicycle is a more sustainable mode of transportation compared to cars or even public transit. However, emissions associated with installation and maintenance of cycling infrastructure may sometimes negate the GHG benefits associated with additional cycling. We discussed gaps in the current literature and directions for future research.
