Sierra Leone faces significant climate-related challenges, including rising temperatures, unpredictable precipitation patterns, and increased risks of extreme weather events, which threaten its infrastructure and coastal communities. This assistance assessed Sierra Leone's public investment management through the Climate Module of the Public Investment Management Assessment (C-PIMA). Sierra Leone was found to perform moderately well in some areas of the C-PIMA, but there were key gaps in other areas, often linked to weaknesses in the underlying public investment management framework. The assistance found that addressing these persisting core public investment management challenges is a prerequisite for effective climate-sensitive public investment management.
