Random House has done it. Scholastic has done it. Even a publisher of the Bible is going green. So hey, Simon & Schuster: welcome aboard! The publisher, which counts such notables as Stephen King and Ursula Hegi among its authors, has committed to increasing its recycled-paper content from the current 10 percent to 25 percent or more by 2012. It will also buy at least 10 percent of its paper from Forest Stewardship Council-certified sources by 2012, “endeavor to eliminate the use of paper that may contain fiber from endangered and old-growth forest areas,” and make shipping cartons “exclusively from 100 percent recycled post-consumer waste, subject to availability.” We could do without the loopholes, but it’s a start — after all, the journey of a thousand Green Miles begins with a single step.
