The purpose of this paper is to provide a practical framework to guide governments in catalyzing and scaling up public and private investment in Blue Carbon as part of their blue economy development. It does this by describing in detail a Blue Carbon Readiness Framework, a step-by-step, well-illustrated guide with simple checklists. Client countries can use the illustrations and checklists to determine their readiness to catalyze and scale up investment in blue carbon credit finance. The Blue Carbon Readiness Framework consists of three pillars: 1. Data and Analytics; 2. Policy and Institutions; 3. Finance.
