Climate Finance is an important catalyst for providing and leveraging actions necessary for mitigation and adaptation to climate change impacts. Pacific small island developing States (SIDS) are some of the most vulnerable countries in the world to the impacts of climate change yet accessing climate finance for most of these countries continue to be an ongoing challenge. Pacific SIDS also continue to lag behind other developing countries in scaling-up their climate finance from other sources, particularly from the private sector. This paper seeks to shed light on the climate finance architecture and experience of the Pacific SIDS as well as provide some way forward that donors and development partners in the region could consider in strengthening Pacific SIDS; abilities to scale-up climate finance. This study adopts a desk review approach, synthesizing relevant climate finance related literature from within the Pacific and as well as external sources.
