We survey institutional investors on firms’ climate risk disclosures. Many investors believe climate risk reporting to be as important as traditional financial reporting and that it should be mandatory and more standardized. However, they also view current quantitative and qualitative disclosure on climate risks as being insufficient and imprecise. The belief that current climate-related disclosure is deficient derives more from investors that believe climate risks are underpriced in equity markets. We complement the survey analysis with archival data showing that greater institutional ownership is associated with a higher propensity of firms to voluntarily disclose their carbon emissions.
