To date, there is very limited experience with collective reporting by countries or organisations to the UNFCCC. Thus, further work would be needed to outline how this could be taken forward: while collective reporting of climate finance mobilised bilaterally may entail relatively small process changes, collective reporting of climate finance mobilised multilaterally could entail large ones (e.g. reporting of information from non-Parties), as could any review of collectively-reported information. If the COP could provide detailed guidance regarding the information to be included in future reports, this could increase the utility of such reports in quantifying mobilised climate finance in the context of the UNFCCC.
