Sustainable banking, guided by Environmental, Social, and Governance (ESG) criteria, is gaining prominence as a vital strategy for fostering sustainable development in Africa. This review explores the integration of ESG factors within the African banking sector, highlighting its significance, challenges, and potential benefits. ESG integration in banking involves incorporating environmental considerations such as climate change and resource management, social factors including community development and employee welfare, and governance aspects like ethical practices and transparency into banking operations and decision-making processes. The review begins by examining the current state of the African banking sector, noting the unique economic and regulatory landscapes across the continent. It identifies key challenges in financial inclusion, economic development, and regulatory compliance that underscore the need for sustainable banking practices. The review then delves into the specifics of ESG integration, outlining strategies for environmental sustainability, such as green financing and reducing carbon footprints, social initiatives like corporate social responsibility (CSR) programs and financial literacy initiatives, and governance improvements through robust ethical frameworks and enhanced transparency. Case studies of leading African banks demonstrate successful ESG integration, illustrating the positive impacts on financial performance, reputation, and stakeholder trust. However, the review also acknowledges significant barriers to ESG adoption, including lack of awareness, high implementation costs, and regulatory hurdles. To address these challenges, the review recommends policy support, capacity building, and collaboration with international organizations. This review underscores the critical role of sustainable banking in Africa's development, advocating for a more integrated approach to ESG factors. By aligning banking practices with sustainability goals, African banks can contribute to long-term economic growth, social equity, and environmental protection, ultimately fostering a more resilient and inclusive financial system across the continent.
