At its third session, the Ad Hoc Working Group on Further Commitments for Annex I Parties under the Kyoto Protocol (AWG) invited Annex I Parties, in a position to do so, to submit to the secretariat, by 22 June 2007, information and data on the mitigation potential of policies, measures and technologies at their disposal, with a view to providing a basis for indicative ranges of emission reduction objectives by Annex I Parties. It requested the secretariat to prepare, under the guidance of the Chair of the AWG, a technical paper that synthesizes these submissions and available information, inter alia, considering factors and criteria, relevant to the determination of the mitigation potential and to the identification of possible ranges of emission reduction objectives of Annex I Parties. The secretariat has prepared document FCCC/TP/2007/1 in response to this request. The secretariat has received four such submissions. In accordance with the procedure for miscellaneous documents, these submissions are attached and reproduced in the language in which they were received and without formal editing. The secretariat has also received one submission from an accredited non-governmental organization. In line with established practice, the secretariat has posted this submission on the UNFCCC website
