More than 700 million trees are needed for annual consumption of office paper. Every year, each office employee produces 160 kilograms of paper waste, and 45% of all papers are thrown away within 24 hours after printing. In order to preserve the environment and inform the public about the rational ways of paper handling, the “Paperless Day” campaign is held all over the world. Its organizers urge people to do as much as they can in their everyday life and at work without paper industry products.
