The Small Island Developing States (SIDS) together bear next to no responsibility for climate change, but their geographical, socioeconomic and climate profiles make them particularly vulnerable to its impacts. Spread across three regions, the 39 SIDS nations have received USD 1,772 million from multilateral climate funds between 2003 and 2019. This amount finances 334 projects in 38 SIDS (all SIDS have received finance except for Singapore). While approved funding for the SIDS has increased markedly in the past few years, it fulfils only a small part of actual needs. Since 2015, the Green Climate Fund (GCF) has been the largest contributor to SIDS. In 2019, USD 110 million was approved for projects in SIDS. Some 60% of this is programmed by the GCF, which also accounts for the eleven largest projects in SIDS. Further scaling up both climate adaptation and mitigation finance to the SIDS is vital – both to address the vulnerability of SIDS inhabitants by making agriculture, biodiversity and infrastructure sectors more resilient to climate impacts, and to shift the energy mixes of SIDS away from fossil fuels.
