In Brazil, home to 20% of the world’s water supply, a large dependence on hydroelectricity has spurred water shortages and disparate household access. CLASP investigated the viability of introducing water efficiency policies in Brazil that could conserve natural resources and address the climate crisis.

CLASP modeled the potential impacts from water efficiency policies, finding relatively small carbon reductions as just under half of all Brazilian households heat their water. Of those, 97% use electric showers, representing one immediate opportunity for water efficiency policy intervention. The report suggests that greater water conservation could be achieved by including cold water fixtures in water efficiency policies.
