We provide new evidence in examining whether external auditors price environmental responsibility initiatives when performing the audit of financial statements. We also examine how investors value the firm when environmental initiatives occur in conjunction with higher audit fees. Results show environmental initiatives are positively associated with audit fees, but the extent of this association varies across the five different types of environmental initiatives we consider. We further find that auditors appear to price environmental initiatives due to their risk rather than additional audit effort. While environmental initiatives may be costly from an audit standpoint, investors value (Tobin's Q) firms more highly when environmental initiatives occur in conjunction with higher audit fees. Collectively, our findings imply that auditors price environmental initiatives into the audit and investors value firms more highly when auditors consider this social responsibility.
