Interview with the Author of Sustainability Studies in Print

Since Sustainability Studies in Print: Five Printers Discuss Their Journeys to SGP Certification, is the book of the month, we interviewed the author, Joe Deemer, about the content of the books and some of the methodology behind it. 

What level of understanding/commitment is Sustainability Studies in Print aimed toward? Is it for someone curious about embracing bits and pieces of sustainability? Or someone who wants to go all the way toward SGP Certification?
