This article presents, an analysis of the opinions of assurance providers regarding the quality and the limitations of sustainability reports and their recommendations to improve them using the Global Reporting Initiative as a framework. The qualitative content analysis of 301 assurance statements for sustainability reports from mining and energy companies provides a comprehensive view of the main outcomes of the assurance process, including its limitations, the application of the GRI principles and suggestions for improving sustainability reports. Taking into account the (...) perceptions of practitioners a priori well informed on the quality of sustainability reports—namely assurance providers—this paper complements the current literature on sustainability reporting and its assurance, including critical approaches that question the reliability of sustainability reports, stakeholder engagement and the accountability of reporting practices. This study contributes to the debates surrounding the quality of sustainability reports, the added value of assurance statements and the ethical issues underlying the assurance process. It also contains important practical implications for auditors, standardization organizations and stakeholders. (shrink)

The objective of this paper is to investigate, through a qualitative study based on 38 semi-structured interviews with agents who provide assurance of sustainability reports, how they perceive and manage ethical issues underlying the verification of sustainability reports. Most of the ethical issues observed involve four interconnected aspects: the commercialism underlying sustainability assurance, the symbolic nature of the verification process, interdependency between auditing and consulting activities, and familiarity with the audited companies. The findings shed light on the reflexivity of assurance (...) providers on these issues and the legitimation strategies used to explain how they reconcile the independence and impartiality required for auditing activities with commercial aspects related to client–provider relationships. The study also shows the role of contextual variables in the ethics of assurance services. The paper contributes to the literature on the legitimacy of sustainability assurance and commercialism of the audit function. Practical implications and avenues for future research are also developed. (shrink)

The main objective of this study is to understand the value of environmental, social, and governance (ESG) disclosure assurance in the context of the development of sustainable finance standards and laws. This study is based on an analysis of 188 comment letters submitted by such actors in the context of public consultations on the development of three new sustainable finance initiatives (the CFA Institute, the Financial Conduct Authority in the UK, and the New Zealand parliament). The study shows these actors' (...) nuanced and often quite critical perceptions of the effectiveness of external assurance in preventing greenwashing and their reservations about its mandatory nature. These actors have raised various criticisms, including concerns about the vagueness surrounding verification practices; the lack of expertise available to conduct assurance in a new, specialized, and complex field; the costs of the assurance process, particularly for small players; and the lack of control over the reliability of the ESG data used. This article contributes to several emerging trends in the literature—in particular, research on governance practices to prevent greenwashing, on the institutionalization of sustainable finance standards and laws, and on the role of rational myths in the assurance process for ESG disclosures.
