In 2014, the small start-up TREEDAY was founded to tackle pressing issues at the intersection of climate change, sustainable consumption and digitalization. After three years of intensive IT development, scientific discussions and USP building, TREEDAY now employs 15 people from different disciplines and backgrounds and hosts over 10.000 registered users and 6.250 active Green Economy enterprises. With this strong network TREEDAY not only wants to promote sustainable consumption, but also encourage and facilitate communication among responsible producers and consumers.
