Tonight at the stroke of midnight, bookstores will be open for business, selling the final installment of Harry Potter, but there is more to cheer here than just the culmination of the saga. According to National Post, Harry Potter and the Deathly Hallows may be the greenest book in publishing history, because 16 publishing houses are using recycled or ancient forest friendly (AFF) paper to print this book. For New Yorkers, that is the equivalent to 200,000 trees, roughly 2.5 Central Parks' worth. The push to print green started with Raincoast Books in Canada, who now print 98% of their titles on AFF paper. With projected sale figures in the millions, going green to print the final installment of Harry Potter is a wonderful example to the rest of the publishing industry,and one picked up by American publisher Scholastic, who, for the first time, will also be printing the book on greener paper. Will you be reading The Deathly Hallows this weekend? Do you feel better about reading it, knowing that it is printed on recycled/AFF paper?
