Paris Rulebook Transparency Deeper Dive

This guide provides a detailed technical exploration of the reporting and review requirements established by the Paris Agreement Rulebook's enhanced transparency framework. It outlines the specific information Parties must report, the timelines for submission, the structure of the technical expert review and multilateral consideration processes, and the flexibility provisions available to developing country Parties based on their capacities.

• Under the Paris Agreement, Parties are required to report five specific types of information: national greenhouse gas inventories, progress toward achieving Nationally Determined Contributions (NDCs), climate change impacts and adaptation, support provided or mobilized for developing countries (required for developed countries), and support needed or received (for developing countries).
• The primary reporting mechanism is the Biennial Transparency Report (BTR), with the first reports due by 31 December 2024. Most Parties must submit these at least every two years, though Small Island Developing States (SIDS) and Least Developed Countries (LDCs) may report at their own discretion.
• The review process consists of a technical expert review and a facilitative, multilateral consideration of progress (FMCP). Technical reviews can be conducted as desk reviews (remote), centralized reviews (single location), or in-country reviews. The technical expert review team is prohibited from making political judgements or reviewing the adequacy of a Party's NDC, domestic actions, or provided support.
• Developing country Parties that need it in light of their capacities can apply self-determined flexibility across various reporting and review areas. This includes flexibility in the number of gases reported (minimum of three instead of seven), the starting year for time series (reference year of NDC and 2020 onwards instead of 1990), and the timeframe for reporting inventory data (three years prior to submission instead of two).
• The enhanced transparency framework is integrated with other Paris Agreement elements: it informs the Global Stocktake on emissions and NDC progress, links to the Article 15 expert committee for compliance (e.g., failure to submit a BTR), and allows Adaptation Communications to be submitted as part of a BTR.
