Alliance of Small Island States (AOSIS) is an intergovernmental organization of low-lying coastal and small island countries. AOSIS was established in 1990, ahead of the Second World Climate Conference. The main purpose of the alliance is to consolidate the voices of Small Island Developing States (SIDS) to address global warming.

These island countries are particularly vulnerable to climate change and its related effects on the ocean, including sea level rise, coastal erosion and saltwater intrusion. The members are among the nations least responsible for climate change, having contributed less than 1% to the world's greenhouse gas emissions.^[2][3][4] These states advocate for international policy and mechanisms for addressing the inequity of climate impacts.
