Business is beginning to understand how important a commitment to sustainability is in its strategic positioning and long-term economic well-being. This awareness of the issue—if not demonstrable performance—is becoming mainstream in business thinking. It is critical to the designer, as a trusted advisor to business on communication and positioning issues and as a crafter of design artifacts, that the profession also make these issues mainstream in its thinking. We hope that this primer will address myths and misconceptions that reduce the impact of design, help designers understand the criteria they should use in taking a project to print, and address practical questions that will help.
