Here is a really good idea from WWF: a new unprintable file format.
We all know PDF files and recognize that it is really useful to share big documents in this format. Moreover you can read it easily, don’t have to print it so you can save paper. However a lot of people print their pdf out to read or archive them. That’s why WWF created a new format: .wwf which is the same principle than a pdf but it is impossible to print it out. So in saving and sharing your documents as WWF files you save trees.
This video is a good demonstration of this new green file format.
Isn’t it simple and a good initiative?
