The Conference of the Parties serving as the meeting of the Parties to the Kyoto Protocol (CMP), at its seventh session, requested the Joint Implementation Supervisory Committee (JISC) to draft a revised set of key attributes and transitional measures dealing with possible changes to the joint implementation (JI) guidelines, and to present them for discussion to the CMP at its eighth session, with a view to developing revised JI guidelines for adoption at its ninth session (decision 11/CMP.7). This document responds to this request by presenting the revised set of key attributes in the form of draft modalities and procedures for JI. Recommendations regarding transitional steps to manage the transition of JI from the current JI guidelines to the new JI modalities and procedures recommended by the JISC have also been provided by the JISC and are contained in the annual report of the JISC to the CMP (FCCC/KP/CMP/2012/4)
