Towards comprehensive corporate sustainability reporting: an empirical study of factors influencing ESG disclosures of large Czech companies

Purpose Businesses nowadays face unprecedented pressures from stakeholder groups to become more transparent by issuing comprehensive reports describing their environmental, social and governance (ESG)-related activities, strategies and policies. This paper's primary motivation is to understand which ESG disclosure factors are relevant for large Czech companies. Design/methodology/approach To achieve the above-stated goal, the total ESG disclosure index, consisting of three subindexes (ESG) was constructed and calculated for the 100 largest Czech companies. Furthermore, the relationships between firm-level factors and ESG disclosure indexes were estimated by using censored regression models. Findings This study found that revenue, number of employees and profitability positively influenced the total ESG disclosures. On the level of the three ESG components, this study found that revenue positively impacted environmental and governance disclosures while the number of employees positively affected social and governance disclosures. Moreover, profitability affected social and governance disclosures positively for large Czech companies. However, this study did not observe a significant relationship between board attributes and ESG disclosures. Originality/value This paper extends academic literature on ESG disclosures by verifying the significance of firm-level factors in the context of Czech business realities before the adoption and transposition of the Corporate Sustainability Reporting Directive. More specifically, this study has investigated the ESG reporting together and separately for ESG factors. This separation is vital as firms vary in reporting processes across these factors.
