本論文は、道路輸送の脱炭素化における炭素価格とグリーンファイナンスの相互作用を、ScopusとVOSviewerを用いた文献計量分析で整理した。両分野の研究は増加傾向にあるが、道路輸送文脈での統合的理解は断片的であることを示す。環境ガバナンス・グリーン経済・持続可能な交通の研究クラスターを可視化し、今後の研究ギャップを提示する。

English

This bibliometric study maps the literature on carbon pricing and green finance in road transport decarbonization using Scopus and VOSviewer. It finds growing academic interest but fragmented integration of the two instruments in the transport context, and identifies research clusters around environmental governance, green economics, and sustainable mobility.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では炭素税・GX経済移行債・EV普及政策が議論される中、道路輸送の脱炭素を財政・金融両面から捉える視点は、SSBJ開示や企業の移行計画策定に示唆を与える。ただし日本固有の事例分析は含まれない。

In the global GX context

Amid global debates on carbon pricing (EU ETS, CBAM) and transition finance, this paper synthesizes how fiscal and financial instruments jointly drive transport decarbonization. It offers a useful evidence map for ISSB/TCFD-aligned transition planning, though it is a bibliometric overview rather than new empirical evidence.

📄 Abstract（原文）

Abstract In the face of the escalating climate crisis, the decarbonization of road transport and the transition towards a low-carbon economy have become strategic priorities for governments, particularly given the transport sector’s significant contribution to global greenhouse gas (GHG) emissions. In this context, carbon pricing and green finance have emerged as two complementary policy instruments capable of accelerating the sector’s transformation. Carbon taxation seeks to internalize the environmental costs associated with GHG emissions within economic decision-making, while green finance aims to mobilize the financial resources required to support sustainable development, enhance energy efficiency, and promote the adoption of lower-carbon mobility solutions. Despite the growing body of research in both fields, their interplay within the specific context of road transport decarbonization remains relatively fragmented in the scientific literature. This study is based on a systematic review of the scientific literature, primarily using the Scopus database to gather relevant publications on carbon pricing, green finance, and road transport. Bibliometric tools, notably VOSviewer, were employed to analyze and visualize keyword co-occurrence networks, author collaborations, and citation linkages to map the interactions among core concepts. The objective is to identify research trends, major contributions, and scientific gaps concerning the role of carbon pricing and green finance mechanisms in driving the low-carbon transition of the transport sector. The findings highlight a steady rise in academic interest regarding how fiscal instruments and sustainable investments support transportation decarbonization. Additionally, keyword and co-author networks reveal distinct research clusters focused on environmental governance, green economics, and sustainable transport development. These results underscore the critical importance of carbon pricing and green finance as key catalysts for transforming road transport systems. Keywords: Carbon pricing, carbon tax, green finance, climate finance, road transport, decarbonization, sustainability.
