More specific estimates of future spending are even rarer: only one-third of respondents could provide estimates of climate-specific finance for the upcoming year. At COP 16 in 2010, reporting provisions for Annex II countries on climate finance were extended to become more frequent via biennial reports. As previous analysis has shown (Ellis and Moarif, 2015), the guidelines for reporting climate finance information in national communications and biennial reports overlap significantly, but are not a complete match with each other nor with the coverage of the USD 100 billion per year commitment.
