The NDC synthesis report is prepared in response to the requests from COP 21 (Paris, 2015) and CMA 2 (Madrid, 2019) to the secretariat to prepare a synthesis report of the NDCs submitted by Parties before COP 26. In view of the postponement of COP 26 to November 2021 and the impact of the COVID-19 pandemic on the NDC preparation process, the secretariat decided to issue the NDC synthesis report in two editions. This initial version synthesises information from 48 new or updated NDCs, representing 75 Parties, submitted as at 31 December 2020 in accordance with decision 1/CP.21. These 75 Parties represent about 40 percent of Parties to the Paris Agreement and account for about 30 percent of global GHG emissions.
