A literature review on environmental concerns in logistics: trends and future challenges

This study contributes to the discussion in that, the study integrates reverse logistics, closed-loop logistics, green logistics and environmental logistics in a review and presents a generic conceptual model for understanding the implementation process of environmental practices in logistics. However, little effort has been reviewed on environmental concerns in logistics such as reverse logistics, green logistics, closed-loop logistics/supply chain and environmental logistics. The 2009-2018 data was collected from the Scopus and Web of Science. The metadata analysis reveals descriptive information such as influential authors, journals, subject area, top publishing countries, most common words used in the titles etc. The content analysis reveals the development of four broad classifications of the extant literature, namely concept and theory development, drivers and barriers, presentation of optimisation models and assessment and evaluation.
