This study investigates the relationship between female representation, women as chief executive officers, and corporate sustainability disclosures in Swedish listed companies. The used data was collected from the Swedish listed companies in Nasdaq Stockholm for the period 2017-2020. The specific research period is due to the new amendments of the Swedish Annual Accounts Act (Årsredovisningslagen) which came into force 2017. To investigate the effect female representation, and women as chief executive officers have on the legally issued corporate sustainability disclosures, this study applies content analysis and quantitative methods. By estimating multiple regression models, the results revealed a non-significant relationship of female representation on the board of directors and of women as chief executive officers, on the quality of corporate sustainability disclosures. For the critical mass of at least three women, a non-significant impact is detected. Lastly, an additional test for reversed causality has been conducted, however no significant relationship was documented.
