RT Journal Article T1 Assurance of corporate social responsibility reports: Does it reduce decoupling practices? A1 García Sánchez, Isabel María A1 Hussain, Nazim A1 Aibar Guzmán, Cristina A1 Aibar Guzmán, Beatriz K1 CSR assurance K1 CSR decoupling K1 GRI guidelines K1 Legitimacy theory K1 Reporting quality AB Recent research shows the existence of a selective corporate social responsibility (CSR) disclosure strategy that creates a gap between CSR disclosure and actual performance. These CSR decoupling practices compromise the credibility of CSR reports and have triggered a demand for the adoption of credibility enhancement mechanisms, such as adherence to the global reporting initiative (GRI) reporting guidelines, and the external assurance of CSR reports. The effectiveness of such mechanisms is not clear, however. This paper draws on legitimacy theory and addresses the issue of symbolic versus substantive use of assurance, and compliance with GRI reporting standards, by analysing their effect on CSR decoupling using an international sample of 1,939 companies (15,219 observations from 2002 to 2017). Analysis of a sub-sample of 708 firms (3,730 observations from 2011 to 2017) also shows that the application of GRI guidelines and the specific characteristics of the assurance provider—accountant, experience and specialisation—reduce CSR decoupling practices. The results provide researchers, managers, assurance providers, investors, stakeholders and regulators with additional insight into the value of the external assurance of sustainability reports and have important managerial and policy implications.
