PurposeIn the last few years, the European context has been characterised by a high degree of attention paid by policymakers, practitioners and academics to the effects related to the transposition of Directive 2014/95/EU by the member states. In particular, one the main issues of the intervention made by the European Commission is represented by the theoretical misalignment between corporate communications and actions. According to this evidence, this paper aims to shed light on this debate through a critical evaluation of the effectiveness of Directive 2014/95/EU.Design/methodology/approachThe analysis was built using panel data analysis on a sample of 813 European listed companies. Furthermore, the authors performed additional analysis and robustness checks to assess the reliability of the analysis.FindingsThe analysis underlined the enabling role of the reporting scope, external assurance and corporate social responsibility (CSR) committees on sustainability reporting. Furthermore, the research highlighted the need to pay specific attention to the real contribution provided by companies to the sustainable development goals.Research limitations/implicationsThe research provided theoretical insights into the effects related to mandatory sustainability reporting, which represents an emerging field in accounting research.Practical implicationsThe analysis revealed the limited effects of Directive 2014/95/EU. In this regard, the paper contributes to the debate about accounting regulation in Europe.Originality/valueThis paper will shed light on the role of Directive 2014/95/EU in sustainable development. To the best of the authors’ knowledge, this is the first attempt to analyse CSR decoupling in Europe after the transposition of Directive 2014/95/EU by the member states.
