PACC Experiences No. 2: Using cost-benefit analysis to inform climate change adaptation projects

Abstract

Cost–benefit analysis (CBA) is a process for identifying, valuing and comparing costs and benefits of projects. It can help inform decisions about whether to proceed with a project or not, which project option to select, and what refinements can be made to improve project design. CBA is also an effective way to help integrate climate risk considerations into project design, and to engage officials from areas such as planning and finance on climate change related issues.
