Umbrella review in Green Supply Chain Management (GSCM): Developing models for adoption and sustaining GSCM

The abundance of literature reviews in Green Supply Chain Management (GSCM) poses a challenge to making objective, evidence-based decisions due to information diffusion. Few studies systematically summarize these reviews to address this challenge. This study aims to conduct an umbrella review, analyzing existing reviews to identify current trends and enhance our understanding of the GSCM adoption process. A sample of 70 review papers was collected using a systematic approach. Quantitative findings reveal growing publication trends, with China leading in contributions, the Journal of Cleaner Production as the top journal, and Joseph Sarkis as the leading author. Bibliometric analysis using VOSviewer identifies Srivastava's study as the most impactful review paper. Qualitative analysis using NVivo 12 classifies reviews into systematic, narrative, and integrative categories. Additionally, the study presents an integrated framework for understanding GSCM adoption and a green innovation cycle model for sustaining green practices. This research contributes to the literature by providing an umbrella review in the GSCM area, offering classifications based on methodology, and developing practical models for GSCM adoption and sustaining it. The study concludes with implications and identifies areas for future research
