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 'plan-implement-review' cycle, including the submission of Nationally Determined Contributions (NDCs), the enhanced transparency framework, and the global stocktake process to increase climate ambition over time.

• The Paris Agreement operates on a 'plan-implement-review' cycle where countries submit NDCs every five years, implement them, and review progress to inform future, more ambitious plans. This cycle is supported by a global stocktake every five years to assess collective progress toward long-term goals.
• At COP24, countries agreed that NDCs implemented starting in 2031 (those communicated in 2025) must have common timeframes. However, the specific length of these timeframes remains unresolved, with options including five-year, ten-year, or a '5+5' compromise approach.
• To address transparency gaps in initial NDCs, COP24 established a detailed list of information for 'clarity, transparency and understanding' (CTU). This list is required for a country's second NDC and focuses on emissions levels, sectoral coverage, and underlying methodologies.
• Developed countries are required to communicate projected finance information every two years starting in 2020. This includes the projected amount of finance, how it will be programmed (channels and instruments), and contributors' policies and priorities.
• The enhanced transparency framework replaces previous UNFCCC arrangements with a common set of guidelines for all countries. All parties must submit biennial transparency reports (BTRs), with the first BTRs due by December 31, 2024.
• The global stocktake is conducted in three phases: (1) information collection and preparation, (2) technical assessment involving thematic dialogues on mitigation, adaptation, and means of implementation, and (3) consideration of outputs at the COP in the year of the stocktake (e.g., 2023).
• An expert-based committee was established to facilitate implementation and promote compliance. The committee can be triggered if a country fails to submit required documents (like NDCs or BTRs), requests assistance, or if there are 'significant and persistent inconsistencies' in transparency reports (with the country's consent).
• Guidelines for cooperative implementation, including carbon markets and Internationally Transferred Mitigation Outcomes (ITMOs), were not agreed upon at COP24. Key unresolved issues include how to avoid double counting and whether a share of proceeds from crediting mechanisms applies to ITMOs.
