This thesis examines the effect of pressure to disclose earnings per share by managers on the quality of environmental information disclosure of companies, whether they affect each other or not, and the moderating effect of corporate governance will also be examined. For this purpose, we use data from companies listed on the Tehran Stock Exchange in the time period ۱۳۹۱ to ۱۴۰۱ to examine this relationship. It is expected that as the pressure to disclose earnings per share increases, the quality of environmental disclosure will decrease, and our results not only facilitate the identification of factors inhibiting the disclosure of environmental information by companies, but also provide insights to encourage companies under pressure to disclose earnings per share to disclose high-level environmental information and realize sustainable green development.
