Abstract
Climate change has reshaped global financial systems by altering risk structures, capital flows, and investment priorities. Three financial mechanisms—climate-risk insurance, green bonds, and carbon markets—have become central in supporting climate adaptation, mitigation, and resilience. Yet, despite their interdependence, scholarly work seldom analyses them together as components of a unified climate-finance ecosystem. This paper proposes a conceptual and empirical framework integrating these three instruments. We investigate how insurance mechanisms address climate-induced physical risks, how green bonds mobilize large-scale sustainable investment, and how carbon markets incentivize decarbonisation. Using a multi-layered comparative analysis, we evaluate risk–return characteristics, regulatory differences, institutional adoption, and cross-instrument linkages. Case studies from Europe, India, and emerging markets illustrate how these instruments behave under different policy settings. We also develop a systems-level model demonstrating feedback loops: insurance pricing affects carbon-intensive sectors’ premiums; carbon markets influence decarbonisation pathways, altering the creditworthiness of green-bond-financed projects; and green investments reduce long-term insurance claims by lowering physical risk exposure. Findings suggest that integrated deployment of these instruments accelerates climate resilience, enhances pricing efficiency, and reduces systemic financial instability. Policy implications include the need for harmonized taxonomies, improved risk disclosure frameworks, and blended finance structures. The paper concludes with a research agenda for modeling cross-instrument financial flows and quantifying climate-induced tail risks.
