Rather, it draws on examples of current practice to identify barriers, challenges and emerging lessons, and presents opportunities highlighted by practitioners and experts where development co-operation can play a role in improving the effectiveness of international public climate finance. The interviews were conducted over the phone and in person. The individuals participating in the interviews represented seven governments and a non-govemmental organisation (NGO) in recipient countries of international climate finance, nine climate finance providers from bilateral donor agencies and multilateral development banks, and nine international organisations and research institutes categorised for the purpose of this paper as "supporters” of climate finance. This subset of practitioners and researchers working on international climate finance has been selected to represent views from developed and developing countries, with the aim to provide initial insights, as a starting point for further discussion.
