At its twentieth meeting, the Joint Implementation Supervisory Committee (JISC) agreed on two areas for further work in 2010: concept of materiality in determinations and verifications; and changes to projects during implementation following completion of the determination in accordance with paragraph 33 of the JI guidelines. In this context, the JISC requested the secretariat to launch a call for public input regarding the concept of materiality in determinations and verifications, and changes during project implementation from a determined project design document and/or monitoring plan. The inputs from this public call will be compiled in an information note to be considered by the JISC at its twenty-first meeting and will be taken into account in preparing new or revised relevant documents. This call has been launched and will be open for inputs until 26 March 2010 (see ).
