This research investigates the potential effects of companies' commitments to disclose their anti‐corruption efforts on their sustainability performance. Additionally, we aim to analyze whether the existence of a sustainability committee influences this relationship. To achieve these objectives, we gathered data from 5344 firm‐year observations of companies listed on the FTSE 350 index from 2008 to 2023. Our findings provide strong empirical support for a positive relationship between companies' anti‐corruption disclosures and their sustainability performance. Furthermore, our evidence suggests that the presence of a sustainability committee acts as a viable complement to anti‐corruption disclosures, driving improved sustainability performance. Our study highlights practical implications for organizations, regulators, and policymakers, and it opens avenues for future research.

This paper considers the anti-corruption disclosure reporting of the large UK-quoted extractive companies from 2003 to 2019. This period includes the introduction of the 2010 UK Bribery Act, which might be expected to influence corporate disclosure. It takes content analysis metrics from the environmental reporting literature, which is a more developed area of research, and considers an area with a higher volume of corporate disclosures. It applies these metrics to investigate the trends in corruption reporting over time and the impact of the introduction of the Act on reporting breadth and depth. We find that some of the metrics would appear to add more insight than others in this new context. We conclude that the volume of reporting has grown over time, but this would seem to be in breadth, more questions addressed rather than more depth to the answers given. There has been a step-change in reporting since the introduction of the Act, though concluding whether this has increased quality may depend on your perspective and interest as a user of the information.
