In Sweden, concrete has traditionally been manufactured with glaciofluvial deposits as fine aggregate. In 2004 the production of this aggregate was approximately 21 million tons. Due to environmental reasons and local shortage of this natural resource there exists a goal to reduce the production to 12 million tons in year 2010.

The National Ready Mixed Concrete Association says that, during production, each pound of concrete releases between 5 percent and 13 percent of its weight in carbon dioxide. Assuming the middle range of 10 percent, the carbon dioxide released in the construction of a mile of a single interstate lane is: 0.1 x 8.7 million = 0.87 million pounds of carbon dioxide.
