In 2013, CPI tracked USD 10 billion in climate finance flows between non-OECD countries (Buchner et al., In 2014, eight non-Annex I countries provided development co-operation funding of more than USD 500 million, led by Saudi Arabia and the UAE; for most countries, it is not clear what share of these resources is being used for climate purposes.17 Given their importance, having more clarity on these flows would allow for a better overview of where and how support is being provided. Some developing countries are starting to report on financial support provided for development purposes more systematically, via bilateral or multilateral flows, for example in publicly-available government documents (e.g. Brazil, Mexico) or through reporting to the OECD DAC (e.g. Korea, UAE).18 In 2014, the OECD estimated the development co-operation flows of the seven non-DAC and non-OECD developing countries that do report to the DAC at USD 19.4 billion.
