Biennial assessment and overview of climate finance flows (BA)
The UNFCCC Standing Committee on Finance's flagship two-yearly report mapping global climate finance flows — who pays, who receives, and whether flows match needs.
Expert review openNo editor-accepted expert review yetDefinition
A technical report prepared every two years by the UNFCCC's Standing Committee on Finance (SCF) under a mandate from COP 17 (2011), providing an overview of climate finance flows — including their geographical and thematic balance — and an assessment of their adequacy against needs. It supports the COP's function of measuring, reporting and verifying support provided to developing countries.

Overview
What it means
The BA is the climate regime's most comprehensive official mapping of climate finance: it aggregates data from sources such as the OECD, multilateral development banks, and initiatives like the Climate Policy Initiative, covering flows from developed to developing countries and South–South cooperation.
The seventh edition (2026) for the first time draws on biennial transparency reports (BTRs) for data on support provided and received, and reflects on the new collective quantified goal on finance (NCQG).
How it is used
Negotiators, researchers and advocates use BA figures to argue over whether the USD 100 billion goal was met, the balance between mitigation and adaptation finance, grant versus loan composition, and progress toward the NCQG agreed at COP29.
Why it matters
Climate finance disputes run on numbers, and the BA is the agreed reference point: its findings shape trust between developed and developing countries and the credibility of the finance track at each COP.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
