Navigating the Paris Rulebook

This guide from the World Resources Institute explains the technical requirements for ex-ante climate finance information under the Paris Agreement Rulebook, detailing the types of data to be communicated, the responsible entities, the biennial timeline, and how this information links to other Paris Agreement mechanisms.

• Parties are required to provide indicative quantitative and qualitative information regarding financial resources intended to assist developing country Parties. This includes projected levels of public financial resources, details on programs (channels and instruments), policies, priorities (including geography and gender responsiveness), and the purposes of support such as mitigation, adaptation, technology transfer, and capacity-building. It also requires information on how resources are determined to be 'new and additional', methodologies used for projections, and plans to mobilize additional climate finance.
• The responsibility for communicating ex-ante finance information falls primarily on developed country Parties, while other Parties providing resources are encouraged to do so voluntarily. The process involves a biennial cycle starting in 2020 for submissions, with subsequent processes—including compilation and synthesis reports by the Secretariat, in-session workshops, and high-level ministerial dialogues—beginning in 2021.
• Ex-ante finance communications are distinct documents and are not to be included in biennial transparency reports or other documents; they are instead recorded on a dedicated online portal established by the Secretariat. The CMA and COP are tasked with considering the resulting synthesis and summary reports from workshops.
• Ex-ante finance information is linked to several other Paris Agreement elements: it informs the Global Stocktake via the Secretariat's synthesis report, helps developing countries inform their adaptation plans and communications, and is subject to the Article 15 expert committee if a Party fails to submit its communication. However, the link to the Enhanced Transparency Framework is indirect, as Article 13 focuses on ex-post finance, and comparisons between ex-ante and ex-post data are not mandated.
