Markets are increasingly competitive, placing significant pressure on companies to excel both presently and in the long term, given the rapid pace of change. Within a triple bottom line framework encompassing environmental and social considerations, corporate sustainability is linked to heightened financial performance. Fintech tools are leveraged to empower companies, executives, investors, and customers in managing their financial transactions using diverse software and specialized applications. Green Fintech innovation represents a fresh approach, leveraging technology for financial services, initiated by start-ups, established tech firms, or traditional financial institutions, all aimed at enhancing the flow of financial resources for sustainable development. Its primary contribution lies in enhancing and broadening the environmental finance theory while providing comprehensive empirical evidence. Moreover, the chapter proposes effective measures and recommendations targeting local governments, financial institutions, and enterprises based on empirical findings. Local governments ought to prioritize policy implementation and assess operational impacts, financial institutions must continually bolster the provision of advanced digital financial products and services, and enterprises should emphasize the adoption of digital financial tools to facilitate green and low-carbon development in the future.
