The Introduction of Mandatory Environmental Reporting Guidelines: Australian Evidence

This article augments the empirical literature on environmental reporting through an analysis of the impact the introduction of mandatory reporting guidelines had on the environmental disclosures of seventy‐one Australian companies. Specifically it documents three implications from the enactment in 1998 of s. 299(1)(f) of Australia's Corporations Law that requires companies to report on their environmental performance with respect to any ‘particular and significant environmental regulation’. First, from a review of annual reports for two reporting periods prior to and two periods post the operative date of the provision, there was found to be a significant increase in the number of companies reporting and the level of information provided on environmental performance. Second, considerable variation was identified in the approaches adopted for reporting, hence confirming concerns expressed as to the practical application of the provision. Finally, there was an increase in the level of total environmental disclosure, most significantly for those companies that reported breaches of regulations and that do not issue a stand‐alone environmental report. The analysis directly links increases in reporting and the introduction of s. 299(1)(f), therefore highlighting the limitations of continual reliance upon voluntary reporting to provide consistent substantive information on environmental performance. In addition, the analysis provides evidence that the introduction of additional reporting media influences the level of disclosure of environmental information within the annual report.
