The OECD held a seminar on Extended Producer Responsibility Programme Implementation and Assessment, from 13-14 December, 2001. The main purpose of the seminar was to examine how governments are implementing EPR policies and to discuss their results achieved. The seminar created a forum for member governments to share information about their EPR programmes, discuss pressing issues and to explore ways to implement sounder and more effective EPR policies. The seminar was divided into four sessions: two sessions consisted of panel presentations from member governments, academia, industry and other experts and two sessions comprised discussion of two consultants’ papers with discussants. Over 50 participants attended the seminar, representing government, industry, academia and non-governmental organisations. The outcome of session discussions and recommendations gave OECD clear directions on where to focus its future EPR activities. In particular, participants stressed the need for further guidance on economics of EPR as well as the need for empirical data on the costs and effectiveness of EPR so as to allow for more conclusive policy and programme analysis. The Proceedings of this seminar are divided into two parts: Part One consists of papers from Sessions 1 and 2. Part Two contains papers from Sessions 3 and 4. The Proceedings contain only papers submitted to the seminar; no presentations are included.
