Evaluating the determinants of environmental, social and governance (ESG) score is significant for topic for academics and regulators and companies. Despite its importance, little attention has been paid to non-financial strategy disclosure and how to communicate non-financial information. However, in the recent years, attention to the topic has considerably increased as demonstrated, in the European context, by the introduction of the non-financial reporting directive in 2014. Therefore, it is important to analyse how the quantity and quality of disclosure influence the ESG score. To explore this relationship, a configurational analysis aimed at 31 Italian listed companies was studied by fuzzy-set qualitative comparative analysis. The results showed that there were three path types driving the ESG score and that integrated reporting played a highly significant role in promoting a high ESG score. Specifically, we show the importance of assessing the combinations of quality and quantity disclosures for ESG score through configurational thinking. These results provide a first theoretical basis for the effectiveness of disclosure measurements on ESG score, charting the future direction for environmental management studies.
