Exploring the Nexus of Electric Vehicles, Environmental Health and Sustainability: A Comprehensive Bibliometric Review

This study analysed 636 papers from the Scopus database using bibliometric and graphical techniques to trace the evolving research on sustainability, environmental health (EH), and electric vehicles (EVs). Research patterns, notable authors, most contributing nations, associations, leading journals, and the most widely referenced publications were all noted. Although the top journals for EV policy research are Sustainability and Journal of Cleaner Production, Sovacool Bk is acknowledged as the most active contributor. The top two contributions are the USA and China, underscoring their vital roles in the creation of EVs and creative policies. The primary contributor to the field research is Tsinghua University. With the maximum citations, the study by Egbue (2012) in Energy Policy suggests a significant long-term influence. The study uses Bradford's Law to confirm that important research is concentrated in specific publications and Lotka's Law to analyse author productivity. The results indicate that certain authors are quite prolific, which are in line with Bradford's Law but not Lotka's Law. The seven thematic clusters that emerged were (a) "Sustainable transportation and policy," (b) "Sustainable mobility and energy," (c) "Environmental Impact and Circular Economy," (d) "Electric Vehicles Adoption and Climate Change," (e) "Battery and Lithium-Ion Technology," (f) "Shared and Connected Mobility," and (g) "Smart Grid and Vehicle-to-Grid Integration." Overall, the study highlights the importance of interdisciplinary EV research as well as the need for infrastructure, regulatory, and technology improvements to support sustainable EV adoption. By employing keyword co-occurrence analysis, the study offers academics and policymakers valuable information, establishing the framework for resolving problems and promoting innovation in the EV ecosystem.
