The UNDP has launched report that provides a step-by-step guide to developing countries in setting up national climate funds and in making informed decisions on climate financing options. This guidebook is based on UNDP’s experience with 750 funds comprising over US$5 billion in resources from various donors. The guide aims to assist governments in planning, financing and delivering on their climate policies. Noting that there are over 50 international public funds, 45 carbon markets and more than 6,000 private equity funds that provide billions of dollars to finance national-level climate change actions, it stresses that the proliferation of funding mechanisms increases the transaction costs for developing countries seeking climate finance. The guidebook underlines that while investments in the clean energy sector grew up to 30% in the estimated amount of US $243 billion dollars in 2009-2010, only one tenth of these resources were invested in countries outside of the G-20, including Small Island Developing States (SIDS) and Least Developed Countries (LDCs).
