Like most problems we face in life, increasingly there’s an app for it. By creating a digital connection between our water and ourselves, WaterSmart has made keeping up with the Joneses as easy as turning off a tap. This innovation is part of Sustainia100; a study of 100 leading sustainability solutions from around the world. The study is conducted annually by Scandinavian think tank Sustainia that works to secure deployment of sustainable solutions in communities around the world.
