Global climate finance is at a historic institutional inflection point facing a massive capital gap. According to the Climate Policy Initiative's Global Landscape of Climate Finance 2026 report, global climate finance surpassed $2 trillion for the first time in 2024, with growth to $2.1 trillion estimated in 2025, but annual growth has decelerated sharply from 30% in 2021 to 2-3% in 2025. By 2030, annual global climate finance需求 is projected to reach $9 trillion——a "climate finance cliff" of approximately $7 trillion per year between current flows and target needs. The Green Climate Fund (GCF) has unlocked an additional $4 billion through balance sheet efficiency reforms, increasing available funding from $1.37 billion to $5.65 billion over the next two years; the Asian Infrastructure Investment Bank (AIIB) reported that climate finance represented 67% of its total approved financing in 2024, with 27% invested in adaptation projects. However, current climate investment decision-making still lacks a mathematical framework capable of integrating physical climate risk, transition risk, policy risk, and financial returns into a unified measurement system. Based on the eight-dimensional framework of Prim‑Lex theory (Economic Climatology) —— Prim‑Unity·Prim‑Fire (climate project energy metabolic efficiency and carbon mitigation benefits), Two Principles·Yin‑Yang (investment balance between climate mitigation and adaptation), Three Realms·GC⁴A (cross‑scale climate governance integration from international commitments to national planning to project implementation), Four Phenomena·Four Colors (four‑phase differentiated investment strategies for climate projects), Five Elements·Five Models (coupling of metabolic deficit, phase‑transition risk, spatial zoning, carbon balance sheet, and project resilience), Six Dimensions·Six Directions (spatial synergy and regional allocation of climate investment), Seven Luminaires·Seven Rhythms (multi‑period cash flow synchronization of climate projects), and Eight Trigrams·Eight Information (information entropy of climate investment networks) —— this paper constructs, for the first time, an eight‑dimensional quantitative assessment system for climate investment decision-making. Using three empirical cases —— GCF Central Asia regional projects, AIIB climate adaptation bonds, and China's climate investment pilot zones —— this paper demonstrates the standardized application pathway of the eight‑dimensional framework in climate project screening, risk pricing, and benefit assessment, providing a quantifiable, programmable, and auditable mathematical language and decision-making tool for the transition of global climate finance from "scale expansion" to "precision allocation."
