No one gets to net zero by themselves. We all recognize the need to work together across the entire book value chain to make our processes more efficient, to reduce waste and recycle and reuse. Yet, one curious area of the book business are book returns. Returning unsold books for credit or refund is considered an essential part of the bookselling business. In the process, we ship books between retailers and warehouses, try and resell return copies and ultimately end up pulping unwanted titles. The latest report from RISE Bookselling, a project led by the European and International Booksellers Federation (EIBF), investigates seven case studies of how book returns work in European and international countries. We reached out to Daniel Martin Brennan and Tora Åsling, Policy Advisor and Policy Officer at the European and International Booksellers Federation (EIBF) for more details.
