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.

Information needed to facilitate the clarity, transparency and understanding of mitigation contributions

Parties to the United Nations Framework Convention on Climate Change are currently developing the operational elements of the Paris Agreement, including guidance for information to facilitate clarity, transparency and understanding (CTU) when Parties communicate their nationally determined contributions (NDCs). Drawing on Party submissions from 2016 and April 2017, and discussions held during the CCXG Global Forum on the Environment and Climate Change in March 2017, this paper synthesises and discusses views on guidance for CTU in four areas: the purpose of the guidance; where further guidance is needed; the elements of the guidance; and the relationship between guidance for CTU and other operational elements of the Paris Agreement. The paper then suggests ways for Parties to consider selected issues, namely: the structure and content of the guidance; its status; the scope of NDCs; and links between sets of guidance, including timing issues.
