EXPLAINING THE Paris Agreement RULEBOOK

The document provides a comprehensive overview of the Paris Agreement Rulebook, which operationalizes the Agreement's long-term goals through a continuous cycle of planning, implementing, and reviewing Nationally Determined Contributions (NDCs). It details key outcomes from COP24 in Katowice, including the adoption of guidelines for the Enhanced Transparency Framework, the Global Stocktake, and projected finance information. The guide also identifies unresolved issues, such as the specific length of common timeframes for NDCs and the rules governing cooperative implementation and carbon markets.

• The Paris Agreement operates on a 'plan-implement-review' cycle designed to increase climate ambition over time. This process involves countries communicating NDCs, implementing them, and reviewing progress through individual assessments and a collective global stocktake every five years to inform subsequent, more ambitious NDCs.
• At COP24, countries agreed that NDCs implemented starting in 2031 must have common timeframes, which applies to the NDCs due for communication in 2025. However, the specific length of this timeframe remains undecided, with options being five years, ten years, or a '5+5' compromise.
• To resolve transparency gaps in initial NDCs, the Rulebook establishes a detailed list of information for 'clarity, transparency and understanding' (CTU). This is required for all NDCs starting with the second submission, though countries are encouraged to provide it by 2020.
• Developed countries are required to provide projected finance information every two years starting in 2020. This includes the projected amount of finance, how it will be programmed (channels and instruments), contributor policies, and domestic processes to make climate finance more predictable for developing nations.
• The Enhanced Transparency Framework (ETF) replaces previous UNFCCC arrangements with a common set of guidelines for all countries, though flexibility is available for developing nations. All countries must submit Biennial Transparency Reports (BTRs), with the first due by December 31, 2024.
• An expert-based committee has been established to facilitate implementation and promote compliance. It can be triggered by a country's request, a failure to submit required documents (such as NDCs or BTRs), or non-participation in transparency processes.
• Significant disagreements persisted at COP24 regarding cooperative implementation and carbon markets. Unresolved issues include the prevention of double counting for Internationally Transferred Mitigation Outcomes (ITMOs), the application of a share of proceeds for vulnerable countries, and the transition of Kyoto Protocol units.
