When choosing paper for office printers, local governments can turn to an online calculator that compares the environmental effects of paper made with different levels of recycled content. Developed by New York-based Environmental Defense, The Paper Calculator provides information about the amounts of energy and wood used to make different types of paper. Users can see how using less paper or changing paper specifications can reduce environmental effects. The calculator also helps users measure and communicate the environmental benefits of their paper choices. View the online tool at www.papercalculator.org.
