Every year, Ooligan Press publishes a book in our OpenBook Series that is sustainably printed as part of our ongoing commitment to environmentally conscious publishing. One of the components of this process is conducting an environmental audit on the printing, which is then written up and included in the front of the book for readers to see. The importance of sustainable publishing has been frequently expounded upon both by the publishing industry at large and by Ooligan Press itself, so much so that to say “sustainable publishing is crucial to our planet’s future” is a well-known fact. What many may not know, however, is the determination process by which a book is published environmentally. Namely, the audit performed on the printer to ensure the most sustainable practices and resources were used during the printing of the book.
