According to the Green Press Initiative, more than 30 million trees are used to make books to be sold just in the United States every year. After J.K. Rowling urged the company to make changes, Scholastic printed 65 percent of the U.S. first edition of Harry Potter and the Deathly Hallows on Forest Stewardship Council (FSC)-certified paper. This means that it was created from responsibly managed forests, and contained at least 30 percent post-consumer recycled paper. These differences made a severe impact. 200,000 trees were saved, making the same carbon impact as if you were to take 1,577 cars off the road.

The print runs in the United Kingdom and Canada were 100 percent recycled.
