There has been some limited experience of collective reporting of mobilised climate finance (e.g. OECD, 2015a, which also addressed attribution of mobilised climate finance to different actors; MDBs, 2016). Further work would be needed if collective reporting of climate finance is to be taken forward in the UNFCCC context, as it could entail significant changes in the transparency framework, such as the reporting of information from non-Parties. There is some precedent of communicating climate finance information to the Conference of the Parties to the UNFCCC (COP) by non-Parties who are operating entities of the UNFCCC’s financial mechanism. The COP could provide relevant guidance regarding the information to be included in future reports, for example on quantifying mobilised climate finance in the context of the UNFCCC, which could increase the utility of such reports.
