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. The report projects that at the present rate of consumption, two-thirds of the world’s population will live in water-stressed conditions by 2025.
Buildings continue to be environmentally demanding after construction has been completed. Buildings and the built environment account for 30 percent of all greenhouse gas emissions in the United States and 30 percent of all waste products – some 136 million tons annually. As a major contributing factor to climate change, greenhouse gases have had a detrimental effect on the health of the planet, including rapid and perhaps irreversible melting of Arctic polar sea ice.
