However, as suggested above, there are numerous political and technical challenges to measuring and reporting this information. In addition, Parties are also not specifically requested to undertake, nor to report on, policies and actions that would contribute to making finance flows consistent with low-emission and climate-resilient development pathways. For information on such policies and actions, the global stocktake could draw on outside processes (e.g. the Millennium Development Goals, G20 work on climate finance and the work of other non-governmental and intergovernmental organisations). The approach of the transparency framework under the Paris Agreement reflects the universal and self-differentiated nature of NDCs, and the specific obligations of developed countries to provide financial resources and other support to developing countries.
