“Es war einmal ein Baum…” (once upon a time there was a tree…) is a non-profit sticker project for dealing with paper more consciously. The sticker advertises a more thrifty use of paper at places where usually lots of paper is consumed. Studies from the US show that there can be saved up to 30% of paper due to a sticker like that.
Es war einmal ein Baum is an initiative of our own in cooperation with KarmaKonsum, Lokay and of course the US original These Come from Trees.
