Such Parties would need to provide the information needed to track progress towards each of these goals and measures as outlined in Figure 3 and Table 6. The global stocktake will consider, among other things, the overall effect of Parties’ NDCs. For some types of NDC, estimating expected future GHG emissions is difficult and may depend heavily on external factors such as GDP or population growth. The Paris Agreement encourages developing country Parties to move over time towards economy-wide emission reduction or limitation targets in the light of different national circumstances. As more Parties do this, it should become easier to gain a clearer picture of future expected GHG emissions levels and associated global average temperature rise. Article 13 of the Paris Agreement also stipulates that other Parties providing support should report information on support provided and mobilised, and that developing country Parties should report information on support needs and support received.
