The Revenues for Nature (R4N) programme has published its latest guidebook focused on oceans. This guidebook explores how innovative revenue models and financing mechanisms can mobilise private capital to support the protection and restoration of coastal and marine ecosystems. Drawing on a series of real-world case studies from diverse geographies, it examines how different approaches—from user fees and payments for ecosystem services to blue bonds and debt-for nature swaps—have been designed and implemented in practice. The guidebook highlights key lessons, challenges, and enabling conditions for scaling these models, with the aim of supporting policymakers, investors, and practitioners in developing investable, sustainable solutions for ocean conservation.

The R4N programme is a global partnership between the Green FInance Institute, UNEP FI and UNDP Biofin. R4N supports the replication and scaling of revenue models that drive private capital into nature in diverse geographies. You can learn more and read the entire guidebook series at the R4N website.
