Risk Stress Test Tool



Introduction to RIST Stress Testing Tool

The Risk Stress Test (RiST) tool is an Excel-based tool developed to help conduct the stress testing analysis described in the methodological note Integrating Climate Change and Natural Disasters in the Economic Analysis of Projects: A disaster and climate risk stress methodology. The RiST tool has been designed to highlight risks to project outcomes over long time horizons, accounting for risks along three dimensions:

  • Changes in average climate conditions 
  • Impacts from natural disasters, with current frequency and intensity
  • Changes in the frequency of natural disasters due to changes in average climate conditions 

The RiST methodology is linked to the World Bank’s Resilience Rating System (RRS) and provides an approach to obtain an A rating for resilience of a project, the first of two dimensions covered by the RRS.

Training Videos

These training videos provide a step-by-step breakdown of how to apply the RiST tool for incorporating climate and disaster risks in a project’s economic analysis.

Excel Files

Four examples of applying the RiST tool to energy, transport, agriculture, and water sector projects can be found in Appendices C–F in the methodological note. The RiST tool Excel files for each of the case studies are available here:
