This Technical Note builds directly on the Urban Heat Risk Assessment Technical Note, which focuses on diagnosing heat hazards, exposure, and impacts in urban areas. In many cities, the analytical understanding of extreme heat has advanced rapidly, supported by improved climate data, spatial analysis, and growing evidence on health, productivity, and infrastructure impacts. As a result, the nature and severity of urban heat risks are increasingly well documented. This note responds to a different, but closely related, challenge. Its purpose is not to further assess or quantify heat risks, but to support cities in translating existing evidence into concrete, investable actions and project concepts. It is intended for contexts where the need to act on heat is already recognized, but where the pathway from assessment to implementation remains unclear.
