A systematic review of metro and low-carbon city: Bibliometric analysis, metro decarbonization and research prospects
The metro has an irreplaceable role in the construction of low-carbon cities by utilizing urban underground space to transfer surface transportation underground. However, existing research lacks systematic analysis of the metro's contribution to low-carbon cities and research on decarbonization strategies for the metro. This study conducts a literature review on the research field of metro and low-carbon city, with the research focus lying in analyzing the current research field of metro and low-carbon city through bibliometrics. First, this study visualizes and analyzes publications in the research field of metro and low-carbon city from 1985 to 2024 through bibliometrics. Then based on the review study of this field, the contribution of metro decarbonization to low-carbon cities is explored from three aspects: carbon source reduction in low-carbon cities, ecological carbon sinks in low-carbon cities, and zero-carbon operation of the metro itself. Finally, this study discusses the current research limitations and future research directions in the metro and low-carbon city research field. The results indicate that the metro will significantly contribute to low-carbon underground cities by concentrating surface transportation underground and conserving aboveground ecological space, while also effectively reducing CO2 emissions through geothermal energy and the wind-photovoltaic‑hydrogen hybrid system.
