The Unprintable WWF Document Format
The World Wildlife Federation aims to combat paper waste with a novel initiative.
The World Wildlife Federation has launched a new file format similar to the popular Portable Document Format (PDF), except for one interesting catch: the file cannot be printed.
The WWF file format was created as a gesture of defiance against unnecessary usage of paper in a variety of settings, most notably the office workplace and the university. It is currently available only for the Mac, but a Windows version is coming soon.
