It contains summaries of the presentations made and the outcomes of the discussions that took place at the workshop. The workshop addressed the questions proposed by the Subsidiary Body for Scientific and Technological Advice at its thirty-eighth session, which were intended to clarify the role and technical design of the new market-based mechanism with the aim of facilitating further consideration and identifying further steps towards fulfilling, at the nineteenth session of the Conference of the Parties (COP), the mandate given at COP 18. Participants engaged in a rich exchange of views, shared ideas, experiences and lessons learned in relation to relevant issues and expressed views on the way forward at the United Nations Climate Change Conference to be held in Warsaw, Poland. Parties may wish to use the information contained in this report to assist them in elaborating modalities and procedures for the new market-based mechanism, with a view to recommending a decision to COP 19 for adoption and consideration
