The role of climate finance mobilisation at all governance levels; international, multilateral, national, subnational, and local, is crucial. Additionally, there is a critical need to enhance the capacity of developing countries to access, allocate and spend climate finance effectively. ICLEI South Asia, under CDKN, has developed a compendium of finance sources and instruments to support climate action in the South Asian countries of Bangladesh, India and Nepal. This compendium aims to enhance awareness of the various climate finance opportunities available in these three countries. It provides an overview of the available climate finance landscape in the region, at the time of writing, in an easy to access and simplified manner.
