The UNDP and Alliance of Small Island States (AOSIS) report highlights key results of the United Nations Framework Convention on Climate Change (UNFCCC) Support Programme, managed through UNDP and implemented by AOSIS. The programme aims to develop partnerships to enhance the visibility, influence and capacities of SIDS in the UNFCCC negotiations to secure a sustainable future. The majority of the funding was provided by the European Commission. The publication provides the rationale, the context, what was delivered, lessons learned and the legacy of the programme.
