Sustainability-linked debt instruments have proliferated rapidly, yet a critical gap persists between contractual ESG commitments and the actual deployment of capital. This study develops and validates a novel quantitative discrepancy index—the Covenant-Allocation Gap Index (CAGI)—designed to measure the divergence between ESG debt covenant specifications and realized capital allocation patterns. Drawing on a multi-source dataset of corporate debt issuances and capital expenditure disclosures, the research employs a design-based quantitative methodology integrating natural language processing of covenant documents, financial statement analysis, and predictive modeling. The CAGI demonstrates strong predictive validity, correctly identifying 89.4% of firms subsequently subject to regulatory inquiry for sustainability-related disclosure irregularities. The index reveals that covenant specificity and third-party verification requirements are the strongest predictors of allocation alignment, while sector-level effects show that energy and utilities exhibit the widest gaps. The findings offer a replicable framework for investors, regulators, and corporate governance scholars to move beyond binary greenwashing detection toward continuous, quantitatively grounded monitoring of sustainability-linked debt integrity.
