GCCA+ Seychelles Factsheet: Cost Benefits Analysis for Climate action in the Seychelles




CBA is a tool for informing decision-making based on comparing the costs and benefits of a project or other investment. It generates numerical values that allow for rapid and intuitive assessments of an investment via a benefit-cost ratio (BCR) showing the dollar value of benefits for every dollar of costs incurred. This measure fits well with the way that people and institutions typically make decisions - namely by seeking to maximise the benefits secured for a given level of spending. As such, applying CBA to climate actions could offer a powerful means of conveying their significance in terms that are compelling and readily understood.
