The Consequences of Mandatory Corporate Sustainability Reporting

We examine the effect of mandatory sustainability reporting on several measures of socially responsible management practices. Using data for 58 countries, we show that after the adoption of mandatory sustainability reporting laws and regulations, the social responsibility of business leaders increases. We also document that both sustainable development and employee training become a higher priority for companies, and that corporate governance improves. Furthermore, we find that companies implement more ethical practices, reduce bribery and corruption, and that managerial credibility increases. These effects are larger for countries with stronger law enforcement and more widespread assurance of sustainability reports. We conclude with thoughts about mandatory sustainability and integrated reporting.
