This paper aims at examining the impact of the green economy on the performance within Malaysia’s banking sector, focusing on the top 10 publicly listed banks. The study adopts a quantitative content analysis approach using the Global Green Economy Index (GGEI) framework, which encompasses market and investment, efficiency sectors, and environmental factors as independent variables. Further, it is important to consider company size, firm age, and leverage as control factors in this study. The assessment of performance is conducted through the utilisation of financial metrics such as Return on Assets (ROA) and Return on Equity (ROE). The utilisation of the feasible generalised least squares model (FGLS) yielded substantial results indicating that business performance is highly influenced by market and investment and environmental initiatives. Additionally, the control variables, namely firm size and leverage, were found to be important drivers in this context. However, efficiency sectors and firm age do not significantly influence firm performance. The research underscores the importance of integrating green economy into business strategies to enhance performance and contribute to sustainable development. Furthermore, the study recommends further research to explore additional factors such as financial development and the adoption of green technologies in relation to this relationship.
