AOSIS (2015a) AOSIS Ministers set priorities before the second week. aosis.org/press-release-aosis-ministers-lay-out-priorities-ahead-of-week-two/. Called on 28 September 2017 A key element of effective climate negotiations is the involvement of different voices in decision-making. Today, there is widespread inequality in the power and representation of different groups in climate negotiations. Already in 2001, Klaus Toepher, Executive Director of the United Nations Environment Programme (UNEP), published a report that indicated that developing countries bore a particularly heavy burden under current climate policy (Nanda 2016: 135), and while AOSIS was incredibly noisy, much remains to be done in terms of the involvement and engagement of small nations particularly vulnerable to the effects of climate change. This paper aims to analyze how AOSIS has been able to significantly influence international climate agreements and discusses ways to leverage the significant progress made by AOSIS nations by further strengthening the voices of vulnerable nations in international climate discussions.
