本論文は、持続可能なファイナンスにおける情報問題を再検討し、金融の存続可能性（V1）と生物物理学的な持続可能性（V2）の間の意味論的な不一致を論じる。ユーロシステムの担保適格性を例に、グリーンラベルがV2の観点からは意味的に空であると主張する。結論として、現在の情報強化策だけでは金融システムの構造的変化を生み出せないとする。
English
This paper critically examines the informational framing of sustainable finance, arguing that financial viability (V1) and biophysical viability (V2) are semantically misaligned. Using Eurosystem collateral eligibility as a case, it shows that green labels and taxonomies increase syntactic information but do not induce operative changes in V2. The paper concludes that without structural reforms, green finance remains a mirror of financial reproduction rather than a membrane connecting to planetary limits.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJや有報でのサステナビリティ開示が進むが、本論文は情報開示のみでは金融システムの実質的変革に不十分であると警告する。日本版SBTやトランジション・ファイナンスの設計において、単なるラベル付けではなく担保や投資行動の改革が必要であることを示唆する。
In the global GX context
This paper challenges the core assumption of global climate disclosure frameworks (TCFD, ISSB) that more information automatically redirects capital. It introduces a semantic viability criterion that could lead regulators to reconsider the effectiveness of green labels and taxonomies, emphasizing the need for structural changes in financial infrastructure such as collateral rules.
👥 読者別の含意
🔬研究者:This paper offers a novel theoretical framework combining semantic information theory with finance, useful for scholars critiquing the effectiveness of green finance.
🏛政策担当者:The paper suggests that disclosure-focused regulation may be insufficient; policymakers should consider reforming collateral eligibility and rehypothecation rules to align finance with planetary boundaries.
📄 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.
