Yamin and Depledge (2004) argue that the UNFCCC regime is characterised by formal and informal coalitions, alliances, and political groups. Blaxekjær and Nielsen (2014) have demonstrated how new groups since COP15 have transformed the narrative positions and negotiations space in the UNFCCC, creating bridges as well as new trenches between North and South in relation to the principle of Common But Differentiated Responsibility. As the UNFCCC regime readjusts after COP21, these new narrative positions and negotiations space should be re-examined. Through original data such as official statements from groups, observations at UN climate conferences (2011-2015), and interviews with delegates and experts, the paper analyses the narrative position of the Like Minded group of Developing Countries (LMDC), an influential political group under the UNFCCC established in 2012. Following Blaxekjær and Nielsen’s (2014) policy-oriented narrative approach to IR the paper analyses LMDC’s identity, the problems identified by LMDC and the solutions to these problems, and the paper identifies five central characteristics of the dominant LMDC narrative. The analysis also touches upon what narrative techniques are used in constructing the LMDC identity. This framework reveals the embeddedness of narratives in practice as they unfold in the formation of new alliances and ruptures in old ones. This paper contributes to the emerging Narrative in IR research agenda with a policy-oriented model of analysis. The paper also contributes to the broader research agenda on the post-Paris UNFCCC regime, and argues that as long as CBDR/RC is a major unresolved issue – an essentially contested concept – as long will the LMDC play a prominent role in the UNFCCC regime.
