The Decision Tree Framework is a robust decision scaling approach from the World Bank that provides resource-limited project planners and program managers with a cost-effective and effort-efficient, scientifically defensible, repeatable, and clear method for demonstrating the robustness of a project to climate change. The framework adopts a bottom-up approach to risk assessment that aims at a thorough understanding of a project s vulnerabilities to climate change in the context of other nonclimate uncertainties. It helps to identify projects that perform well across a wide range of potential future climate conditions, as opposed to seeking solutions that are optimal in expected conditions but fragile to conditions deviating from the expected.
