Guardians of Truth: How to Ensure the Accuracy of ESG Information

Abstract As mandatory environmental, social, and governance (ESG) disclosure proliferates, jurisdictions often adapt financial enforcement mechanisms to complex ESG information, creating regulatory gaps and excesses. Japan relies on resource-constrained public sanctions, leading to under-enforcement; the USA employs investor litigation, which chills disclosure; and the European Union (EU) mandates costly, narrow third-party assurance. To address these structural deficiencies, this article proposes a hybrid model. The analysis begins with a comparative two × two matrix (ex-ante/ex-post × public/private) that maps the enforcement measures of Japan, the USA, and the EU, revealing distinct trade-offs among cost, coverage, and deterrence. An empirical study of Japanese enforcement reveals systemic under-enforcement and the Securities and Exchange Surveillance Commission’s capacity deficits. Findings demonstrate that neither singular reliance on private-led mechanisms (such as third-party assurance or investor litigation) nor resource-constrained public enforcement alone can reliably secure ESG information without distorting incentives. The proposed hybrid strategically allocates tools to their comparative advantage: (i) reserving ex-ante assurance for high-impact, readily verifiable metrics; (ii) enlarging public audit resources for broader disclosures; and (iii) tying private liability thresholds to context-specific materiality reflecting ESG’s qualitative character. Such an integrated framework can achieve a more balanced alignment between investor protection, stakeholder transparency, and compliance costs, thereby reinforcing market trust and avoiding the twin perils of greenwashing and disclosure chill.
