This report has been prepared in response to the requests from COP 21 and CMA 21 for the secretariat to prepare a synthesis report on NDCs submitted by Parties. In view of the postponement from 2020 to 2021 of the United Nations Climate Change Conference to be held in Glasgow and the impact of the COVID-19 pandemic on the preparation of NDCs, the secretariat informed Parties that it would publish two editions of the NDC synthesis report: an initial version by 28 February 2021 and the full version in advance of the pre-COP meeting, scheduled for 30 September to 2 October 2021.
This full version of the report synthesizes information from the 164 latest available NDCs, representing all 191 Parties to the Paris Agreement, including the 86 new or updated NDCs communicated by 113 Parties, recorded in the interim NDC registry as at 30 July 2021, covering 93.1 per cent of the total global emissions in 2019, which are estimated at 52.4 Gt CO2 eq without LULUCF
The COP and CMA guidance3 on the information necessary for clarity, transparency and understanding of NDCs was used as a framework for synthesizing the relevant information contained in the communicated NDCs, which was supplemented by the synthesis of other information included in the NDCs but not covered by the guidance. The synthesized information is presented for all the represented Parties taken together.
