This STAP guidance proposes a common standard for climate risk screening of GEF projects based on the scientific literature and builds on earlier work undertaken over the last several years in response to the Council’s request that STAP examine the effects of climate change on GEF projects. At a minimum, each agency should use a risk screening process that includes four steps (hazard identification, assessment of vulnerability and exposure, risk classification, risk mitigation plan), ranks risks according to a clearly defined scale, and uses the best available data.
