Having common modalities, procedures and guidelines for accounting and reporting could therefore facilitate the global stocktake. Article 4.13 and paragraph 31 of Decision 1/CP.21 establish principles for accounting for the NDCs of all Parties, including transparency, accuracy, completeness, comparability, consistency, environmental integrity, and avoidance of double counting. As will be discussed in Section 5, improved reporting by individual countries on climate finance provided, mobilised and projected, as well as needed and received in the case of developing countries, can facilitate an understanding of aggregate climate finance flows in relation to agreed goals. However, an assessment commensurate with the objective of the global stocktake will require further inputs, including from a range of actors and bodies outside the UNFCCC such as multilateral development banks (MDBs) and international organisations. The global stocktake shall also “inform Parties in updating and enhancing” their actions and support related to implementing the Paris Agreement.
