The trillion-dollar construction sector has exacerbated the significant challenge of global water scarcity. However, a notable gap exists in the availability of a comprehensive water footprint (i.e., water use through supply chain) map specific to the global construction sector and its impact on local water scarcity. Our study developed a water scarcity assessment model …
