This study's objective is to determine the connections that exist between green accounting, sustainable development, and financial performance, as well as the impacts that are mediated between the two variables. Additionally, the research will investigate the implications of these connections. For the purposes of this study, the population consists of a manufacturing business that is listed on the Indonesia Stock Exchange, employs techniques that are environmentally friendly, and operates between the years 2017 and 2020. A method of systematic sampling is used in order to collect data from fifty-two different companies. A route analysis performed using EViews was the approach that was used to evaluate the data. Within the context of this scenario, green accounting has an impact on both sustainable development and financial performance. However, financial performance does not have an impact on sustainable development, and vice versa. The ability of a firm to remain in business over the course of a long period of time is now evaluated based on how well it implements environmentally responsible accounting procedures and how well it performs financially.
