Abstract
E-book is currently trying to take place of Paper-book in western book market because of its competitive price and easy transfer. Additionally, from the viewpoint of environmental load, many environmentalists believe that shifting to E-book would assist establishing low-carbon reading style for readers. When environmental assessment is conducted to compare Paper-book to E-book by utilizing Life Cycle Assessment (LCA) approach, the fact comes out that commonly accepted stereotype should be reconsidered in some way. Paper-book is somehow portrayed as the villain in terms of environmental load, but is not all the time when different scenarios for usage patterns for devices are set out.
