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.


Options to Revise Reporting Guidelines for Annex I and non-Annex I National Communications

This paper outlines options for new reporting guidelines for national communications from Annex I and non-Annex I countries, both for “full” national communications and biennial “updates”. These reports can facilitate the sharing of information between Parties and may be used to assess the implementation of actions and progress towards the Convention’s objectives. There are significant gaps in the current climate reporting framework. These gaps are particularly marked for non-Annex I countries in terms of GHG emissions and trends, mitigation and adaptation actions. There are also gaps in terms of the effect of mitigation actions and support provided and received for climate-related activities, including for technology transfer and capacity building.

This paper suggests that: (i) national communications be produced more frequently while their focus is streamlined; (ii) reporting guidelines be revised to improve transparency about mitigation commitments/actions/targets that countries have indicated to the international community as well as other obligations taken under the UNFCCC and subsequently; (iii) standard reporting formats be used for more of the information in national communications; (iv) a flexible reporting framework be established for non-Annex I countries, where the information in (and possibly timing of) national reports is “tiered” according to national circumstances; (v) an increased emphasis be placed on reporting of “key” issues; (vi) information routinely provided on adaptation measures and policies be formalised; (vii) reporting on “support” be increased and its structure improved; and (viii) in reports from non-Annex I countries, the provision of information that is already routinely provided be formalised.
