The publisher is launching a comic series based on the mythological figure with roots in Paganism under its paperless Eco Comics imprint.
"Green Man has come to represent the environmental movement and our endangered eco-system, and so has more relevance now than ever. It is therefore fitting that his comic book debut will be entirely paperless and published by Eco Comics," said the firm in a statement.
Writer Chris Bunting has teamed up with artist John-Paul Howard for the series, which debuted this week across a variety of digital formats.
Bunting said: "I've written a number of cultural heavyweights but the Green Man is extra special. The mystery surrounding him makes him very intriguing, while an artist's sketches dating from the 1230s could make him the first comic book-style character in history.
"Yet in almost 800 years since, I don't believe that he has ever been given his own story, let alone comic book - until now.
"It is even more remarkable considering that the Green Man influenced Treebeard in J.R.R. Tolkien's Lord of the Rings, Puck in Shakespeare's A Midsummer Night's Dream, and so many comic book characters."
Green Man will become the official mascot of Mohawk's Eco Comics line as the publisher embarks on a number of initiatives to promote environmental awareness.
