• About Us

    Since 1990, AOSIS has represent the interests of the 39 small island and low-lying coastal developing states in international climate change, sustainable development negotiations and processes. As a voice for the vulnerable, its mandate is more than amplifying marginalized voices as it also advocates for these countries’ interests. In terms of size, AOSIS closely resembles the countries it represents on the global stage, but often punches far above its weight, negotiating historic global commitments to cut greenhouse gas emissions, among other achievements.
