Decarbonizing road freight transportation - A bibliometric and network analysis

摘要

Road freight transportation literature increasingly concentrates on environmental aspects to reduce logistics contribution to carbon dioxide emissions. Some literature reviews highlight specific mitigation and adaptation strategies, but the overarching research directions to identify emerging areas and general trends of the field have not yet been clustered or synthesized. This paper presents a systematic quantitative review of the road freight transportation decarbonization literature leveraging bibliographic coupling and network analysis techniques. It contributes to the understanding of road freight decarbonization and provides recommendations for further investigations of the field by systematically mapping the literature body. This way, key research clusters are outlined and visualized to understand the underlying knowledge structure. The findings reveal a diverse and fast-growing research field, which in large parts focuses on route optimizations, last-mile solutions, and alternative fuels, while offering future research opportunities that address organizational barriers currently hindering collaboration and technological or operational measures for longhaul transportations.
