This scoping written by Freyja Vilborg Thorarinsdottir, and published in the journal, Sustainability, 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, the authors 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.
