本稿は、持続可能なファイナンスを情報問題と捉える従来の枠組みを批判し、金融にとっての情報が「意味論的」であるかどうかを問う。RovelliやKolchinsky-Wolpertの理論を援用し、ユーロシステムの担保適格性を事例に、金融の再生産（V1）と惑星境界内での長期的持続可能性（V2）の間の意味論的不一致を明らかにする。グリーンラベルやタクソノミーは構文情報を増やすが、運用上の変化を伴わなければこの不一致を修復できないと結論づける。
English
This paper critiques the conventional framing of sustainable finance as an information problem by asking whether information becomes 'semantic' for finance—causally consequential for a specified viability. Drawing on Rovelli and Kolchinsky–Wolpert, it distinguishes financial viability (V1) from biophysically conditioned viability (V2). Using the Eurosystem collateral complex as a case, it shows that biophysical information can be scrambled at no operative cost under V1, making green labels syntactically rich but semantically empty. Without operational changes, green finance cannot bridge the gap between the two viability functions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本稿は、グリーンファイナンスの情報的アプローチの根本的限界を理論的に示す。日本ではSSBJや有報での情報開示が進むが、開示情報が実際の資金配分に与える影響を再考する契機となる。
In the global GX context
This paper challenges the dominant information-centric paradigm in sustainable finance, arguing that biophysical information may be semantically inert within current financial architectures. For global audiences, it offers a novel theoretical lens to evaluate the effectiveness of disclosure frameworks like TCFD and ISSB in driving real-world change.
👥 読者別の含意
🔬研究者:The paper provides a new theoretical framework to analyze the semantic gap between financial viability and biophysical sustainability in green finance.
🏢実務担当者:The argument suggests that green labels and taxonomies alone are insufficient; operational changes in collateral and risk management are needed.
🏛政策担当者:Regulators should reconsider whether current disclosure mandates and taxonomy-based incentives can actually influence financial flows towards sustainability.
📄 Abstract（原文）
Sustainable finance is usually framed as an information problem: if markets receive better information about climate and biodiversity, prices and allocation will adjust. This paper asks a different question: whether such information becomes *semantic* for finance — causally consequential for a specified viability. Drawing on Rovelli and Kolchinsky–Wolpert, I distinguish two viability functions for wholesale finance: financial viability ($V_1$), defined by settlement, liquidity and collateral acceptability; and biophysically conditioned viability ($V_2$), defined by the long-run persistence of the finance–economy system under planetary constraints. I apply the diagnostic to the collateral complex, focusing on Eurosystem collateral eligibility and euro-area repo markets. The argument turns on a permutation criterion: if two instruments differ biophysically but agree in the parameters governing eligibility, haircutting, substitution, rehypothecation and liquidation, the complex treats them identically, and biophysical information can be scrambled at no operative cost. The collateral complex is semantically rich under $V_1$ and approaches semantic emptiness under $V_2$ on the biophysical dimension as an independent operative variable. Green labels and taxonomies increase syntactic information; absent operative changes they cannot repair this semantic misalignment — an architecture densely responsive to the conditions of its own reproduction and structurally insensitive to the conditions of planetary reproduction.
