This document summarizes key issues regarding the review processes under Articles 6 and 13 of the Paris Agreement. It outlines UNFCCC experiences with reporting and review, issues with the content and timing of Article 6 and 13 reviews, and other scope issues not yet addressed. Key findings include that Article 6 and 13 review provisions are broadly consistent but some clarification is still needed regarding overlapping reporting and responsibilities. Guidance is also needed on substantive aspects of Article 6 reviews and cross-checking adjustments between countries. The timing of Article 6 reviews should also be further clarified.

reported information

4. 4 Climate Change Expert Group
Key issues on the content of Article 6 and 13 reviews
• Comparative assessment of the scope, coverage, and output from reviews
• Review provisions are broadly consistent
• Areas were identified where Article 6 provisions could be developed further in a
coherent way with Article 13 MPGs
• Interplay between the reviews
• Sequencing of reviews and submitting Article 6 review report to Article 13 ERT ,
and experts link
• More clarity needed, e.g. when submitting initial report as stand-alone document
• How review of paragraph 77.d of the MPGs could be conducted
• How to cross check adjustments between two countries engaged in co-
operative approaches
• Option of the centralised reviews;
• Enable automatic checks using ITMOs tracking system

Key issues on timing of Article 6 and 3 reviews

6. 6 Climate Change Expert Group
Key findings
• Reporting and review provisions under the MPGs and draft A6.2 guidance
are broadly consistent; resolving some reporting issues of A6.2 can bring
further clarity on reviews (connected to the proposals made for reporting)
• Importance of legal clarity on review of similar or overlapping information
reported under Article 6 and Article 13 and responsibilities of respective
ERTs (SBSTA work)
• Guidance on substantive aspects of A6 review that needs to be
elaborated (A6.2 guidance and SBSTA work)
• Cross check adjustments between two countries engaged in co-operative
approaches (connected to the proposals made for reporting)
• Guidance on timeline of Article 6 reviews and consideration of two
scenarios (SBSTA work)
