AOSIS in the UNFCCC negotiations: from unity to fragmentation?

Small island states have been able to obtain some remarkable achievements in the climate change negotiations by building a cohesive coalition, the Alliance of Small Island States (AOSIS). Its cohesion, however, has been affected by changes in the UNFCCC process. The increase both in the number of issues on the climate agenda and the number of negotiation groups may have helped or hindered compromise and finding common ground. To track how AOSIS has fared in the climate change regime, the activities and positions of AOSIS, and of individual AOSIS members over three distinct periods (1995–2000, 2001–2005, 2006–2011) in the climate change regime, are compared. It is found that group activity has declined in relative terms and although there is overall agreement regarding mitigation and adaptation, there is less consensus regarding forestry (e.g. LULUCF and REDD) issues. However, despite controversies in some areas, AOSIS has remained a tightly coordinated and cohesive alliance that continues to be a key player in global climate policy.
