The Convention stipulates that efforts to address climate change may be carried out cooperatively by interested Parties. By its decision 5/CP.1, the Conference of the Parties (COP), at its first session, decided to establish a pilot phase for activities implemented jointly (AIJ) among Annex I Parties and, on a voluntary basis, with non-Annex I Parties that so request.
Through the same decision the COP requested the Subsidiary Body for Scientific and Technological Advice (SBSTA) and the Subsidiary Body for Implementation (SBI) to prepare, with the assistance of the secretariat, a synthesis report for consideration by the COP (decision 5/CP.1, para. 2(c)). On this basis, the COP shall, at its annual session, review the
progress of the pilot phase with a view to taking appropriate decisions on its continuation (decision 5/CP.1, para. 3(a)). The present document contains a synthesis prepared by the secretariat in response to the request by the COP and is intended to support the SBSTA and the SBI in the preparation of their synthesis report and recommendations to the COP. This synthesis is based on reports by Parties on national programmes for AIJ under the pilot phase as well as on specific AIJ
