Media exposure, public policy pressure, and environmental disclosure: an examination of the impact of tri data availability

The disclosure of environmental information in corporate financial reports has been a topic of interest within the accounting profession for more than two decades. Previous research shows the extent of this disclosure varies both across firms and across time (see, e.g., Freedman and Wasley, 1990; Blacconiere and Patten, 1994; Gamble et al., 1995; Gray et al., 1995). Not surprisingly, a growing body of disclosure research is focusing on what explains the variation (see, e.g., Gray et al., 1995; Deegan and Rankin, 1996; Hackston and Milne, 1996; Walden and Schwartz, 1997).
