This study examines the normative foundations, regulatory coherence, and systemic implications of international sustainable finance standards governing green investment policies. Employing a non-empirical doctrinal and conceptual methodology, the research evaluates the internal logic, teleological orientation, and comparative divergence of sustainable finance frameworks across jurisdictions. The analysis demonstrates that contemporary regulatory reforms have progressively embedded environmental, social, and governance considerations into financial supervision and capital market governance, yet without fully resolving tensions between market efficiency, developmental policy objectives, and ethical commitments to intergenerational equity. Comparative assessment reveals fragmented implementation patterns that generate asymmetries in taxonomy design, disclosure regimes, and prudential integration, thereby limiting substantive harmonization at the global level. The findings further indicate that sustainable finance operates through overlapping rationalities risk internalization, capital allocation steering, and value-based accountability whose hierarchical relationship remains insufficiently articulated in existing standards. By advancing a structured normative benchmark grounded in long-term financial resilience and systemic stability, this study contributes to theoretical debates in economic stability, banking regulation, and sustainable investment governance.
