Integrating Green Finance and Digital Payment Systems for Sustainable Consumption: A Systematic Review in Emerging Economies

In the era of digital intelligence, organizations and policymakers are increasingly challenged to navigate complexity while balancing economic growth with environmental sustainability. Green finance has emerged as a strategic mechanism to channel financial resources toward environmentally responsible activities, while digital payment systems enable transparency, efficiency, and data-driven decision-making across financial ecosystems. This paper presents a systematic and critical review of peer-reviewed literature examining the integration of green finance mechanisms and digital payment systems as an adaptive and sustainable management practice, with a particular focus on emerging economies. Adopting a structured systematic literature review methodology, the study synthesizes research spanning management, finance, information systems, and sustainability domains. The review analyses how digitally enabled payment infrastructures support green finance objectives by improving traceability of financial flows, enabling micro-level green incentives, strengthening ESG monitoring, and influencing sustainable consumer and organizational behavior. The findings indicate that digital intelligence embedded within payment platforms enhances adaptive management capabilities, institutional accountability, and policy responsiveness, thereby accelerating sustainable consumption and investment transitions. The paper also identifies key challenges related to regulatory alignment, data governance, behavioral resistance, and impact measurement. By consolidating fragmented literature and proposing an integrative conceptual framework, the study contributes to sustainable management scholarship and provides actionable insights for policymakers, financial institutions, and digital platform designers.
