Explaining the Paris Rulebook

This briefing by the World Resources Institute explains the purpose and function of the Paris Rulebook, which consists of implementation guidelines designed to operationalize the Paris Agreement. It details how the Rulebook establishes a cycle of planning, implementing, and reviewing national climate actions to achieve global temperature and resilience goals.

• The Paris Rulebook is designed to transform the Paris Agreement into a functioning system by providing the tools and processes necessary for its full implementation. Its primary purpose is to guide countries on how to plan individual contributions, implement efforts, and review progress to strengthen climate commitments over time, while tracking finance and support for developing countries.
• The Paris Agreement's core goals include limiting global temperature rise to well below 2 degrees C (pursuing efforts for 1.5 degrees C), increasing the ability of countries to manage climate change impacts, and aligning finance flows with low-emissions and climate-resilient development.
• Negotiators are debating several key elements for the Rulebook regarding Nationally Determined Contributions (NDCs), including whether to adopt common implementing timeframes for all parties, what specific information is required for clarity, transparency, and understanding (CTU), and how to define and quantify mitigation targets.
• The Rulebook establishes a common transparency framework requiring all countries to report every two years on national greenhouse gas emissions and progress toward their NDCs. While guidelines are common, flexibility is provided for developing countries based on their capacities, particularly regarding the reporting of support provided, needed, and received.
• The Paris Agreement utilizes a two-phase review process for individual progress: first, a technical expert review to ensure reporting requirements are met, followed by a "facilitative multilateral consideration of progress" where parties can question one another.
• Collective progress is reviewed every five years through a global stocktake (GST), starting in 2023, to assess progress toward the Agreement's long-term temperature, resilience, and finance goals. An initial stocktaking process, the Talanoa Dialogue, occurred in 2018.
• A non-punitive committee is established to facilitate implementation and promote compliance. The Rulebook must determine how cases are referred to this committee, whether through party requests, the committee's own discretion, or via technical expert reviews.
