This paper explores the landscape of sustainable financial management (SFM) in e-banking within Dubai, focusing on the strategies banks implement to promote sustainability and the challenges they encounter. As e-banking continues to expand, sustainability has become crucial for banks aiming to minimise their environmental impact and enhance operational efficiency. The study examines various sustainable strategies, such as the adoption of energy-efficient technologies, the shift towards paperless transactions, and promoting digital customer engagement. Additionally, it considers the regulatory framework and policy support that facilitate sustainable practices in the banking sector, the challenges that banks face, including high implementation costs, technological hurdles, and issues related to customer adoption through case studies. The research illustrates the effectiveness of different approaches and solutions to these challenges. The findings underscore the significance of an integrated strategy aligning economic objectives with environmental sustainability, ultimately benefiting the banking industry and society over time.
