Global impacts of energy demand on the freshwater resources of nations

CIE-MAP researcher Kate Scott published a paper in PNAS on understanding the roles of energy production and international trade in driving pressures on (often scarce) freshwater resources. The authors coupled a trade and hydrological model to examine pressures on freshwater resources associated with energy production across the global economy. While the electric and gas sectors induce freshwater consumption predominantly within countries where demand originates (91% and 81%, respectively), the petroleum sector exhibits a high international footprint (56%). The analysis demonstrates the importance of broadening the discourse on energy policy from greenhouse gas emissions to address issues including freshwater scarcity, the role of international trade, and wider environmental and societal considerations.
