With our project "Green ACT" we want young students to make remarkable records of success in an ideal world to reduce global warming with deceleration of unnecessary mass production, mass consumption and mass disposal by learning and applying the principles of reducing, reusing, recycling, upcycling and downcycling. This project's main aim is to provide the students with an insight into the term "Our Green and Sustainable World" covering it in all aspects: social, economic and environmental.
