Investors may not know the risks climate-related events could have on companies based on public filings, a new report from the Government Accountability Office found. The Securities and Exchange Commission reviews filings to make sure that companies follow federal securities laws in disclosing information to investors. In 2010, the SEC issued guidance on how climate-related information should be disclosed in public filings. But the oversight office cannot fully review the climate-related risks companies disclose in public filings because of inadequate information, according to the independent report publicly released March 22. “When companies report climate-related disclosures in varying formats and specificity, SEC reviewers and investors may find it difficult to compare and analyze related disclosures across companies’ filings,” the GAO reported.
