本研究は、サステナビリティ報告書の外部保証が企業の債務調達コストに与える影響を国際的データで分析。業績の良い企業のみ保証がコスト削減に寄与し、グリーンウォッシング企業は恩恵を受けないことを発見。保証の質や提供主体によって効果が異なり、時間とともに貸し手が学習することを示す。
English
This paper uses international data to examine how lenders perceive heterogeneity in voluntary assurance of sustainability reports. Assurance reduces debt costs only for firms with above-average sustainability performance, penalizing greenwashing. The effect is stronger when assurance is high-quality or ESG rating disagreement is high.

In the global GX context
This study provides global evidence on the value of credible sustainability assurance, directly relevant to ISSB and SEC disclosure frameworks that emphasize assurance. It shows how markets reward substantive verification and penalize cosmetic assurance, informing the design of assurance standards.

📄 Abstract（原文）
This paper examines whether lenders are capable of discerning heterogeneity in the voluntary assurance of sustainability reports and how this capability influences corporate debt financing costs. Leveraging an international dataset between 2010 and 2019, we find that assurance only reduces debt financing costs for firms that exhibit above‐industry‐average sustainability performance, whereas firms with weak sustainability performance gain no such benefit. Lenders effectively penalize greenwashing by discounting cosmetic assurance but reward substantive verification for genuinely sustainable firms. This assurance premium is particularly strong amid high levels of ESG (environmental, social, and governance) rating disagreement, when third‐party data is unreliable. Moreover, lenders incorporate a valuation premium for high‐quality assurance engagements, particularly when the services are provided by accounting firms (particularly Big 4 firms), cover a broader scope, or involve deeper process rigour or more comprehensive statements. Further analyses demonstrate that the heterogeneity in the debt financing cost reduction effect of assurance, conditional on sustainability performance, tends not to be immediate but gradual. Over time, lenders learn to distinguish between credible assurance and symbolic efforts, adjusting pricing accordingly. Our study highlights the nuanced role of assurance in debt markets and underscores the importance of performance‐aligned sustainability disclosure.
