A diversity of funds can have advantages, allowing for specialisation, for example, by focusing on LDCs or on aspects of climate action such as technology. It has also facilitated mainstreaming as climate-related ODA also flows through bilateral and multilateral development programmes. At present climate finance under the UNFCCC is delivered through funds that serve as the Financial Mechanism of the Convention. The Green Climate Fund and the Global Environment Facility are the operating entities of the Convention.
