This conceptual paper investigates the influence of Green Knowledge Management (GKM) on green entrepreneurship by examining its role in opportunity evaluation and green innovation. The main objective of this research paper is to develop a theoretical framework that links GKM with green entrepreneurship which leads to competitive advantages through practices which are sustainable. This research paper combines theoretical insights to propose a conceptual framework which highlights the relationship between GKM, opportunity evaluation, green innovation and green entrepreneurship. Additionally, in this research there is no empirical testing conducted as this study focuses on understanding the theoretical parts of GKM. This paper proposes a conceptual framework which identifies GKM as a path that leads to green entrepreneurship. The framework identifies sustainable opportunities, green innovation, and its contribution to competitive advantage that aligns with Sustainable Development Goals (SDGs). The results of future research are important to validate these relationships in various contexts. Additionally, the proposed framework in this paper will help entrepreneurs to combine GKM practices into their strategies. Furthermore, the pursuit of opportunity evaluation and green innovations achieves green entrepreneurship.
