This research studies the significant contribution of Corporate Social and Environmental Responsibility (CSER) in creating a sustainable and practical approach to the global financial crisis. It reports on the imminent challenges posed by frequent financial disasters that highlights the need to move beyond the already in place financial crisis management mechanisms. Corporate Social and Environmental Responsibility, along with sustainable finance, motivates investments in diverse fields. It includes renewable energy, socially responsible businesses and sustainable technologies. Technological advancements like blockchain and AI (Artificial Intelligence) further improve CSER practices that strengthen financial institutions’ resilience. For this research study, data was collected from a diverse range of financial institutions. It includes banks, investment firms, and insurance companies. This research study underlines the important role of CSER in determining a sustainable and realistic approach in handling and recovering from global financial disasters. The study recommends that financial institutions should integrate CSER principles into their core strategies along with sustainable finance and ethical conduct and integrating technology for transparency and resilience. Also, global cooperation, systematized reporting, and stress testing mechanisms, along with government support and educational initiatives, are important for promoting CSER and safeguarding long-run financial stability.
