Sustainability Reporting: Is Convergence Possible?

Abstract In this essay, we discuss the factors influencing the likelihood of convergence in corporate sustainability reporting. We identify several factors that negatively influence the probability of convergence in the short term. The first factor is the heterogeneity of concepts and definitions surrounding sustainability (e.g. ESG, CSR). This heterogeneity of definitions is pervasive at three levels: (1) across organizations claiming legitimacy in sustainability reporting standard-setting, (2) within standard-setting organizations over time, and (3) across firms reporting about their activities. A second factor is the large number of organizations claiming legitimacy in sustainability reporting. A third factor is related to a diversity of reporting requirements among three influential international standard setters (i.e. EFRAG, ISSB, SEC), leading to various corporate reporting choices. A fourth factor is the diversity in the objectives of standard-setting organizations. Overall, we believe that due to these sources of diversity, the probability of convergence in sustainability reporting appears limited, at least in the short term, although we identify progress in carbon emissions reporting.
