Paris Rulebook Transparency Deeper Dive

The document details the 'who, what, when, and where' of the Paris Agreement's enhanced transparency framework, focusing on Biennial Transparency Reports (BTRs), technical expert reviews, and the facilitative, multilateral consideration of progress. It outlines specific reporting obligations for different Party types, the timeline for BTR submissions starting December 31, 2024, and the self-determined flexibility available to developing countries regarding GHG inventory data and review formats. Additionally, it maps the framework's linkages to NDCs, the Global Stocktake, and compliance mechanisms.

• Parties are required to report five primary types of information: national GHG inventories, progress toward achieving Nationally Determined Contributions (NDCs), climate change impacts and adaptation, support provided or mobilized for developing countries, and support needed or received by developing countries.
• The first Biennial Transparency Reports (BTRs) must be submitted by December 31, 2024. Most Parties must submit these reports at least every two years, and the GHG inventory data included must generally be from two years prior to submission, though some developing countries may use a three-year window.
• 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, centralized reviews, or in-country reviews, and are prohibited from making political judgements or reviewing the adequacy of a Party's NDC or domestic actions.
• Developing country Parties may self-determine their need for flexibility based on capacity constraints. This flexibility can apply to the scope and detail of reporting (e.g., reporting only three GHG gases instead of seven), the time series of data, and the format of the technical review (e.g., choosing a centralized review over an in-country review).
• The enhanced transparency framework is integrated with other Paris Agreement mechanisms: it provides essential data for the Global Stocktake, informs the Article 15 expert committee on compliance (specifically regarding failure to submit BTRs), and is linked to the accounting and achievement of NDC mitigation targets.
