This guide by the World Resources Institute explains the 'Paris Rulebook,' the implementation guidelines for the Paris Agreement adopted largely at COP24 in Katowice, Poland. It details the cycle of planning, implementation, and evaluation of Nationally Determined Contributions (NDCs), the enhanced transparency framework, and the mechanisms for global stocktakes and compliance.

• The Paris Agreement operates on a five-year cycle of planning, implementation, and evaluation. This 'ambition mechanism' requires countries to submit updated NDCs every five years, with each subsequent plan intended to be more ambitious than the previous one.
• At COP24, countries agreed that NDCs implemented from 2031 onwards must have common timelines, affecting the NDCs to be communicated in 2025. However, the specific duration of these timelines (e.g., 5 years, 10 years, or a '5+5' compromise) remained undecided.
• To address transparency gaps in initial NDCs, the COP24 rulebook established a detailed list of information required for clarity, transparency, and understanding (CTU). This is mandatory starting with a country's second NDC, though early adoption is encouraged.
• Developed countries are required to provide biennial predictive financial information starting in 2020. This includes the planned amount of funding, the channels used (such as bilateral or multilateral funds), and the instruments employed (grants or loans).
• The Enhanced Transparency Framework introduces Biennial Transparency Reports (BTRs), with the first submissions due by December 31, 2024. This framework applies a common set of guidelines to all countries, while providing limited flexibility for developing nations based on their capacities.
• The Global Stocktake is a process occurring every five years to assess collective progress toward long-term goals. It consists of three phases: information collection and preparation, technical assessment (including dialogues on mitigation, adaptation, and support), and the final consideration of outcomes at the COP.
• An expert committee was established to facilitate implementation and promote compliance. The committee can intervene if a country fails to submit a required document (like an NDC or BTR), if a country requests assistance, or if there are 'significant and persistent inconsistencies' in transparency reports, provided the country consents.
• Significant disagreements persisted at COP24 regarding cooperative approaches and carbon markets, specifically concerning the avoidance of double counting and the transfer of Internationally Transferred Mitigation Outcomes (ITMOs).
