If you are curious about how your office paper stacks up against other papers or if you want to know the environmental impact of different recycled contents, check out this paper calculator from the Environmental Defense Fund.  Our office uses 100% post consumer recycled paper for all our printer, copier and fax needs.  The EDF paper calculator estimates that for every 100 pounds of 100% post consumer paper our office uses we contribute to zero new wood harvest, save 1 million BTU's of energy, reduce our greenhouse gases by 171 lbs of CO2 equivalent, save 519 gallons of wastewater adn 59 pounds of solid waste.
