The “Ad-hoc Working Group on Long-term Cooperative Action under the Convention” (AWG- LCA) is established exclusively to conduct negotiations on a Copenhagen deal. The group was established at the Climate Change Conference in Bali and assembles all192 Parties to the UN Climate Change Convention. The group met for the first time at the Bangkok Climate Change  United Nations Framework Convention on Climate Change.
 
Talks last April where it adopted its work programme for 2008 (see Annex I). In 2008 it will meet three more times: at the Bonn Climate Change Talks (2 -12 June), in Accra (21-27 August) and in Poznan (1-12 December). In 2009 at least four other meetings will take place. The group decided to address at each of these the following five building blocks of a deal on stronger international action on climate change: a shared vision (including a long-term global goal for emission reductions) and enhanced action in the areas of mitigation, adaptation, technology and finance. In addition, each session will pay attention to specific subjects under these elements. For example, during the Bonn session there will be workshops on adaptation, technology and finance. In Accra, there are workshops planned on reducing emissions from deforestation and sectoral action.
