The last decade has seen a substantial increase in implementation and interest in Extended Producer Responsibility (EPR) programs. Such programs assign financial or physical responsibility to producers for their products post-consumption, with the aim of reducing waste disposal, resource conservation, increasing recycling, and encouraging more environmentally-friendly product design. As on-the-ground implementation of EPR programs has grown, an academic literature on the economics of EPR has also developed over the past decade. However, as the existing studies are heavily tilted towards theoretical and conceptual analysis, a number of important questions remain which may be better answered via context-specific case studies.; Therefore, this [report] offers an overview of the key quantitative and qualitative information and questions that follow-up case studies will need to address, with the goal of updating the 2001 OECD report “Extended Producer Responsibility: A Guidance Manual for Governments.”
