By improving the understanding of what climate finance is, and tracking its flows, it can help countries integrate and mainstream climate change considerations into fiscal policy, expenditure planning and programming and to align national climate policies with development policies and budgets. The information and analysis from CPIERs can also provide a useful basis for a more open and transparent discussion on climate-related activities and finance. To date, CPEIRs have been carried out in Bangladesh, Cambodia, Nepal, Thailand, Samoa and Indonesia.
