Blue finance now has credible frameworks and landmark transactions, yet issuers and investors still lack a consolidated, deal-level manual. This book maps use-of-proceeds and sustainability-linked structures to investable ocean and coastal projects across sovereign, municipal, and corporate issuers. It offers step-by-step KPI design, covenant language, and verification/MRV (Measurement, Reporting and Verification) pathways for shipping and ports, fisheries and aquaculture, wastewater and plastics abatement, and coastal adaptation. Signature case boxes dissect Seychelles’ blue bond and Belize and Barbados debt conversions to surface replicable mechanics—guarantees, conservation funds, and governance. With term-sheet templates and pipeline models for EMDEs (Emerging Markets and Developing Economies), the book helps treasurers, arrangers, and asset managers go from policy to bankable deals.
