Several developing countries view their financial support as horizontal co-operation activities between countries providing assistance to each other as partners, including through emphasising investment in productive sectors (notably infrastructure), technical co-operation and training. This would recognise the contribution of other climate finance providers that do not necessarily provide funds that match these definitions or specific categories. Over the past several years, improved transparency of public climate finance provided by developed countries and multilateral development banks has helped with understanding what types of projects and sectors are being financed, in which countries, and to which actors they are being channelled (OECD, 2015a). Having a more complete overview of such information would help identify gaps, needs and ways to improve the provision of funds.
