This scoping review explores the dynamic field of Gender Lens Investing (GLI), examining its evolution from a niche approach to its current status as a widely recognized investment strategy with the potential to contribute to sustainable development and yield social, financial, and economic benefits. This study provides a comprehensive overview of the theoretical foundations of GLI and its practical applications across public equity markets. By conducting research across four major databases, we performed a thematic analysis that identified four principal themes: Benefits and Impacts, GLI Strategies, GLI Instruments and Innovations, and Challenges and Barriers to Implementation. Key findings reveal an increased implementation of GLI in various forms and a gradual increase in publications, reflecting growing interest within academia and industry. Despite these advancements, critical gaps remain in understanding the financial and social impacts of GLI strategies and instruments. While GLI has been broadly defined and implemented, further empirical research is necessary to evaluate the effectiveness of GLI in public equities and its long-term impacts. The limitations of this review include a focus on English-language publications, which might limit the comprehensiveness of the analysis.
