To secure sustainable development gains and build resilience in the region, there is an urgent need to undertake climate mitigation and adaptation action. Despite an estimated $391 billion in climate finance flows internationally in 2014, the gap between available climate finance and the financing required to limit global warming to two degrees Celsius and adapt to unavoidable impacts of climate change is growing. The present paper offers an overview of the climate finance landscape with a focus on the Asia-Pacific region, and of finance flows from international climate funds, multilateral development banks and subregional and national climate finance initiatives.
