In response to the growing recognition that measuring inputs, such as climate finance, is not enough to capture the impacts of investments, the World Bank Group developed the Resilience Rating System (RRS). Developed over a two-year,multi-sectoral consultative process through close collaboration with internal and external actors, the RRS methodology aims to guide investment decisions and improve climate resilience in project design and outcomes. The methodology report is publicly available. The RRS evaluates and rates investment projects from C to A+, based on their resilience attributes in two complementary dimensions. The resilience of rating considers a project's design, reflecting the confidence that it will achieve its expected objectives and maximize development benefits in the face of climate and disaster risks.The resilience through rating considers a project's outcomes and reflects its contribution to improving climate resilience in the broader community, sector and systems, and to driving transformational adaptation. Combining the two dimension ratings provides an overall project rating, from CC to A+A+.
