This note presents proposed terms of reference for the Expert Group on Technology Transfer (EGTT) for developing a set of performance indicators to regularly monitor and evaluate the effectiveness of the implementation of the technology transfer framework and for identifying, analysing and assessing existing and potential new financing resources and relevant vehicles in supporting development, deployment, diffusion and transfer of environmentally sound technologies in developing countries. The Subsidiary Body for Scientific and Technological Advice may wish to consider and endorse the proposed terms of reference, and, if necessary, to provide further guidance to the EGTT
