The relevance of environmental disclosures: are such disclosures incrementally informative?

Abstract

Establishing the information content of transparent voluntary environmental disclosures and the source of this information content is of fundamental importance for corporate social responsibility (CSR) practitioners. Our results indicate that: (1) incremental to information provided by current Toxics Releases Inventory (TRI) data, voluntary environmental disclosures provide valuation relevant information; (2) the various disclosure categories are similar in value relevance, implying that each category is informative of management's current environmental strategies; (3) current TRI is positively associated with cost of capital but there is no association between voluntary environmental disclosures and cost of capital; and (4) taken together, the above results point to a signaling role for such disclosures and financial performance prediction as the means by which voluntary environmental disclosures enhance firm value. This advances the literature by pinning down the source of firm value enhancement of such disclosures. Our results suggest that a proactive environmental strategy and the signaling of such a strategy to investors can enhance a firm's stock price, a finding which will assist CSR practitioners in convincing top management that proactive environmental strategies combined with transparent voluntary environmental disclosures are worthwhile
