At its thirteenth session, the Conference of the Parties (COP), by its decision 1/CP.13 (the Bali Action Plan), launched a comprehensive process to enable the full, effective and sustained implementation of the Convention through long-term cooperative action, now, up to and beyond 2012, in order to reach an agreed outcome and adopt a decision at its fifteenth session. It decided that the process shall be conducted under a subsidiary body under the Convention, the Ad Hoc Working Group on Long-term Cooperative Action under the Convention (AWG-LCA), that shall complete its work in 2009 and present the outcome of its work to the Conference of the Parties for adoption at its fifteenth session.

The AWG-LCA at its first session (Bangkok, Thailand, 31 March - 4 April 2008) agreed to undertake its work, seeking progress on all the elements assigned to it by the Bali Action Plan, and identified specific workshops to be held in 2008.
At the second session (Bonn, Germany, 2-12 June 2008), Parties presented a number of concrete ideas and proposals on how to address the elements of the Bali Action Plan: shared vision, mitigation, adaptation, technology and finance. At its third session (Accra, Ghana, 21-27 August 2008), the AWG-LCA invited its Chair to assemble ideas and proposals into a document which could serve as a first version of a negotiating text. This Assembly document was updated by the Chair of the AWG-LCA, at the fourth session of the Group (Poznań, Poland, 1-10 December 2008).
At the same session, the AWG-LCA agreed to shift into a full negotiating mode. For that purpose, the AWG-LCA also requested its Chair to prepare a document, for consideration at its fifth session (Bonn, Germany, 29 March - 8 April 2009), that would further focus the negotiating process on the fulfilment of the Bali Action Plan and on the components of the agreed outcome.
The Group also requested its Chair to prepare a negotiating text for consideration at the sixth session of the AWG-LCA (Bonn, Germany, 1-12 June 2009). The document took account of the proceedings of the AWG-LCA at its fifth session and of further submission received from Parties by 5 May 2009.
During the sixth session, Parties provided general comments on the structure and content of the negotiating text, stated reservations and objections to elements of the text, and proposed additions and modifications. This resulted in a revised negotiating text (FCCC/AWGLCA/2009/INF.1), which was the basis for discusions at the intersessional informal consultations (Bonn, Germany, 10 - 14 August 2009).  The revised negotiating text, as well as material reflecting the work undertaken at the informal consultations are available here.
