Blue bonds offer a mechanism for channelling capital into marine conservation and sustainable blue economy activities. However, issuing a blue bond is a technically complex and multi-stakeholder process which carry unique requirements and risks that differentiate them from conventional debt instruments, These constraints – which include commitments to environmental impact, use of proceeds tracking, enhanced governance and ongoing reporting – mean that while blue bonds are a potentially powerful mechanism for financing ocean conservation and sustainable use, they are not universally suitable. Governments should carefully weigh their benefits and costs before commencing with issuance.
Part I of this guide provides an accessible introduction to blue bonds and the key factors that should be considered by government officials in ministries of finance, planning and environment when evaluating whether a blue bond is the right financing tool to support sustainable blue economy goals. It explores:
- debt sustainability as a precondition for issuance, and the importance of conducting rigorous analysis using International Monetary Fund (IMF) frameworks to ensure borrowing remains fiscally responsible;
- specific risks and legal considerations that accompany blue bonds, including reputational, environmental performance and governance risks;
- the need for strong policy alignment, legal authority and institutional readiness to manage the additional complexity of a blue bond;
- the importance of a robust pipeline of eligible projects, often the most significant barrier for prospective issuers, underscoring the need for early planning, inter-agency co-ordination and technical support; and
- alternative finance mechanisms such as debt-for-nature swaps, payment for ecosystem services and other financial tools that may be more appropriate in particular contexts.
Part II provides step-by-step practical guidance for governments on preparing, issuing, and managing sovereign use of the proceeds blue bonds. It assists officials to navigate the full life-cycle of issuance, from early strategy and feasibility analysis through to project delivery and post-issuance reporting, which requires the alignment of public financial management systems with environmental objectives, the establishment of a credible Blue Bond Framework, the selection of eligible projects, robust environmental safeguards, and transparent reporting and verification.
