Evaluating the outcome effectiveness of the global reporting initiative transitions

Purpose This paper aims to evaluate the outcome effectiveness of the global reporting initiatives (GRI) transitions by understanding how companies have responded to the changes from G3.1 to G4 and finally to the GRI Standards. Design/methodology/approach A quality disclosure score is developed that incorporates assessments of both the quality of disclosures and the materiality of Australian companies. To analyse materiality, survey data were collected from 187 companies. Disclosure scores are based on a content analysis of the sustainability reports of 12 mining and metals companies and 12 financial services companies that used the GRI Standards from 2011 to 2019 (a total of 213 reports). Findings The study found that the GRI transitions have not led to companies improving the quality of their disclosures on areas considered important for them to achieve their social and environmental goals. Instead, the companies tended to use a greenwashing strategy, where the quality of disclosure of material issues declined or fluctuated over time. Practical implications From a practical perspective, the disclosure score developed in this paper enables managers of companies to recognize a threshold of completeness and to summarize the areas that are not materially relevant to their business. Social implications The results are potentially helpful for investors, shareholders and other stakeholders, enabling them to better understand sustainability reports. Originality/value This study contributes to the body of research in sustainability reporting by providing evidence on the outcome effectiveness of the latest updates in the GRI framework.
