At its thirteenth meeting, the Joint Implementation Supervisory Committee (JISC) discussed the necessity to develop a determination and verification manual (DVM), taking into account the opinions expressed by stakeholders during the UNFCCC technical workshop on joint implementation on 9–10 September 2008 and the inputs from the DOE/AIE coordination forum, and decided to request the forum and interested stakeholders to provide input on what would be the exact nature and purpose of a DVM. In this context, the JISC requested the secretariat to launch a call for public input and compile the inputs for consideration by the JISC at its fourteenth meeting. This call was launched on 5 December 2008 and now has been extended until 5 February 2009. Inputs should be received by the UNFCCC secretariat by this date. The extension of the call for public input is available under the following link: .
