Systematic Review of Green Banking Adoption: Following PRISMA Protocols

Increased environmental concerns have prompted organizations, businesses and countries to act sustainably to accomplish sustainable development goals. Hence, research on Green Banking (GR-banking) has gained popularity as researchers have shown a significant interest in identifying the factors that promote the adoption of GR-banking. Considering Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), this study reviews the articles related to GR-banking adoption or intention until April 2022. The underlying objective is to analyse the studies related to GR-banking adoption or intention, research methodologies and assess the theoretical frameworks used in GR-banking adoption or intention studies. The articles were extracted through a comprehensive key search strategy from the Scopus database and Google Scholar until April 2022. The survey identified only 51 articles that directly addressed GR-banking adoption or intention, indicating a significant knowledge deficit in this field. Empirical studies on GR-banking adoption are relatively higher in number than theoretical studies. Results of this study provide key details on both empirical and theoretical studies and highlight the areas for future studies. The study further highlights that the research on GR-banking adoption or intention is in its infancy, and limited two-dimensional studies have been conducted on GR-banking adoption or intention. Moreover, current studies have not investigated performance outcomes of GR-banking besides exploring a few theories. This study offers multiple insights and identifies important research areas that need to be explored in the future to enhance sustainability and related practices in the banking industry.
