OECD/IEA Climate Change Expert Group Papers

This series is designed to make available to a wider readership selected papers on climate change issues that have been prepared for the OECD/IEA Climate Change Expert Group (CCXG). The CCXG (formerly called the Annex I Expert Group) is a group of government delegates from OECD and other industrialised countries. The aim of the group is to promote dialogue and enhance understanding on technical issues in the international climate change negotiations. CCXG papers are developed in consultation with experts from a wide range of developed and developing countries, including those participating in CCXG Global Forums.

The full papers are generally available only in English.

The opinions expressed in these papers are the sole responsibility of the author(s) and do not necessarily reflect the views of the OECD, the IEA or their member countries, or the endorsement of any approach described therein.


Reporting Tables – potential areas of work under SBSTA and options - Part I

GHG inventories and tracking progress towards NDCs

The Modalities, Procedures and Guidelines (MPGs) adopted at COP24 in Katowice lay out rules for reporting and review under the Enhanced Transparency Framework of the Paris Agreement. The Katowice decision on the MPGs requests the Subsidiary Body for Scientific and Technological Advice (SBSTA) to develop Common Reporting Tables (CRTs) for the reporting of national GHG inventories and Common Tabular Format (CTFs) for information necessary to track progress towards NDCs, to be adopted by 2020. This paper analyses potential issues and options Parties may wish to consider when developing CRTs and CTFs. The widespread use of CTFs for tracking progress towards NDCs can potentially facilitate comparability and aggregation of data and information on collective progress in the future. This paper also develops options for CTFs for reporting on information necessary to track progress made in implementing and achieving NDCs and provides worked examples showing how these options could be used for different types of NDC targets.
