Introduction: When many people think about carbon emissions, they assume that cars and other motorized vehicles are the main culprits. However, building construction uses 30 percent of all raw materials consumed in this country and 12 percent of all available potable water – 15 trillion gallons each year. This level of water consumption is ultimately unsustainable, given that the United Nations World Water Development Report 3, issued in 2009, states that one-third of the world’s population already lacks access to clean water.
