Abstract: Abstract The usefulness of carbon disclosures has been questioned in the literature because they do not truly reflect firm’s carbon performance, suggesting that they may not be useful for risk evaluation and investment decisions. This study empirically tests the usefulness of carbon information voluntarily disclosed by the Italian firms. Our results based on the price model show that there is a positive association between the stock price and carbon disclosures, suggesting that investors find carbon information useful for their investment decisions. We find similar results based on the market valuation model. Additionally, the results reveal that the positive association is especially strong for firms that have established environmental committees on a voluntary basis and also for firms from the highly polluting industries defined by the EU_ETS program, confirming that investors’ positive response is especially strong to carbon disclosures by firms from the highly polluting industries. We also find that the market reacts positively to carbon disclosures by firms with a higher percentage of independent directors on their corporate boards, but the positive association is marginally significant.
