Abstract

The inventory problem in the supply chain has significant implications for a company’s financial performance, as inventory value accounts for approximately 25% of the total value of all assets owned. This paper provides a literature review and current classification of 51 articles on sustainable inventory models in supply chains with green technology investment. We evaluate 51 articles published between 2017 and 2025, focusing on key elements such as mapping existing research, identifying trends, and revealing future research opportunities in two-echelon sustainable inventory management. Mapping analysis aims to identify, visualize, and analyze the relationship between elements in a research field. The results of identifying publication trends or developments in the research field of inventory models in the supply chain, considering carbon emissions, show an increase in the publication of articles. Future research opportunities include developing a two-echelon sustainable inventory model in the supply chain that incorporates green technology investment.
