In order to provide a more complete picture, multilateral contributions should also be taken into account. The OECD Working Party on Statistics propose a possible approach to classifying and reporting both bilateral and multilateral climate finance in the future (in their technical document DCD/DAC/STAT(2011)11). This would require improved capacity and training for data coders. The OECD DAC statistical team has in turn benefited from information gathered by researchers in this area to work with countries where errors were identified and correct statistical entries.
