Abstract	Corporate sustainability claims increasingly influence investor judgments, stakeholder relationships, reputational assessments, and organizational accountability. Yet the credibility of such claims remains uneven because sustainability information may contain qualitative assertions, estimates, forward-looking commitments, complex value-chain data, and selectively defined performance indicators that differ substantially from conventional financial information. This paper develops a conceptual–methodological framework for strengthening assurance over corporate sustainability claims. Drawing on established sustainability-assurance literature, ISAE 3000 principles, the AA1000 Assurance Standard, and research concerning assurance credibility and governance, the study identifies five interdependent assurance dimensions: evidence traceability, materiality testing, assurance-scope clarity, provider independence, and governance follow-up. A structured conceptual synthesis is combined with a scenario-based analytical model to illustrate how assurance architecture can influence the credibility of sustainability claims. Because no primary corporate dataset was supplied, all quantitative values used in the analysis are explicitly simulated and are not presented as empirical findings. The analysis indicates that fragmented or narrowly scoped assurance may provide only limited protection against unsupported or selectively framed sustainability representations, whereas a robust framework linking claim-level evidence, materiality, independent verification, transparent assurance boundaries, and corrective governance can substantially strengthen credibility. The proposed framework positions sustainability assurance not merely as verification of selected indicators but as a governance mechanism connecting corporate claims with evidence, responsibility, and stakeholder-relevant accountability. The study offers a foundation for future empirical testing through corporate-report analysis, experimental research, practitioner surveys, or longitudinal studies of assured sustainability disclosures.
