Coastal and island nations globally are grappling with the multifaceted challenges brought on by climate change, including rising sea levels, overfishing, water insecurity, wetland degradation, and coastal erosion. Blue bonds, as a financial instrument, offer these nations a strategic financing mechanism to invest in mitigating such environmental impacts. Functioning as debt transactions, blue bonds facilitate the refinancing of national debt, thereby earmarking funds for conservation efforts that enhance ecological and economic resilience. These bonds not only potentially reduce national debt burdens by creating favorable financial terms such as lower interest rates and extended repayment periods, but also support sustainable marine and coastal projects, including the protection of critical habitats like coral reefs and mangroves. However, despite their benefits, blue bonds face challenges in risk management, project scalability, efficiency in approval processes, and the precise measurement of environmental outcomes, which complicates their broader adoption. While nations like Belize, Barbados, and Seychelles have demonstrated the potential of blue bonds, the broader viability and sustainability of these instruments in climate change adaptation and mitigation remain under scrutiny.
