Assessing Climate Risk Disclosure Practices Among Multinational Corporations

Abstract

Climate risk disclosure has moved in little more than a decade from a voluntary, marginal element of corporate
sustainability reporting to a widely referenced, and in several major jurisdictions mandatory, component of financial
reporting for multinational corporations. This review synthesizes evidence from the accounting, finance and
sustainability-reporting literatures on three interrelated questions: how far, and how unevenly, has adoption of the
Task Force on Climate-related Financial Disclosures (TCFD) framework and its four-pillar structure (governance,
strategy, risk management, metrics and targets) progressed across multinational firms; how does the quality of
physical-risk disclosure compare with that of transition-risk disclosure; and what does the empirical record show
about the relationship between disclosure and firm-level financial and environmental performance. Drawing on more
than two decades of peer-reviewed studies spanning voluntary carbon disclosure, CDP-based scoring, textual
analysis of climate risk language in regulatory filings, and post-TCFD compliance audits, we find a consistent and
persistent asymmetry: governance and strategy disclosures are comparatively mature and largely qualitative,
whereas metrics-and-targets disclosure, particularly forward-looking, scenario-based quantification of transition risk
exposure, remains the weakest pillar across regions and sectors. Physical-risk disclosure lags transition-risk
disclosure even more severely, with few firms outside a small set of insurance, utility and real-estate companies
reporting asset-level exposure to acute or chronic physical hazards. Sectoral and regional heterogeneity is
substantial, with European and financial-sector firms consistently scoring highest on composite disclosure indices
and reporting quality correlating only weakly and inconsistently with underlying carbon or climate performance, a
pattern the literature has long interpreted through the competing lenses of voluntary disclosure theory and
legitimacy or impression-management theory. We conclude that disclosure volume has outpaced disclosure
decision-usefulness, that comparability across firms remains constrained by the persistence of qualitative,
non-standardized reporting even under a common framework, and that closing the physical-risk and quantification
gaps is the most consequential unresolved challenge facing climate-related financial disclosure as it transitions from
voluntary practice toward mandatory regulation.
