How to save a Tree

YouTube Link

Every day, entire forests are cut down to make paper. Paper that’s senselessly used to print out documents all over the world: websites, emails, even entire reports instead of those few pages that are really needed and read. This happens in spite of the fact that it's easy to avoid printing by saving the document as a PDF. But even PDFs can sometimes also be printed out. So to stop unnecessary printing and encourage a new awareness about the use of paper, we’ve developed a new, green file format: WWF. A format that can’t be printed out. A simple idea that saves trees. Join in. Decide for yourself which of your documents don’t need printing - and save them as WWF.


Save as wwf – save ressources – save a tree

WWF has long worked with companies and consumers to promote responsible paper use and the option to "Save as WWF" compliments and reinforces other well-established campaigns - most notably the "Think Before You Print" initiative. Overall, WWF advocates reducing excessive paper consumption, maximising paper recycling, using Forest Stewardship Council (FSC) labelled papers and choosing papers with the lowest water and climate impact.
