1 ton of 100% virgin (non-recycled) newsprint uses 12 trees. A pallet of copier paper (20-lb. sheet weight) contains 40 cartons and weighs 1 ton. Therefore, 1 carton (10 reams) of 100% virgin copier paper uses 0.6 trees. 1 tree makes 16.67 reams of copy paper or 8,333 sheets. 1 ream (500 sheets) uses 6% of a tree.
