<![CDATA[Sustainability issues are increasingly becoming a concern in the business world, especially for industries that are closely related to the use of natural resources such as pulp and paper. This study aims to analyze the effect of environmental investment and environmental management on the stock market value of pulp and paper industry subsector companies listed on the Indonesia Stock Exchange for the 2019-2024 period. This type of research uses a quantitative approach with secondary data. The population in this study were all pulp and paper industry subsector entities listed on the Indonesia Stock Exchange during the 2019-2024 period, totaling 9 companies with 5 samples obtained that had passed the purposive sampling technique. The results showed that environmental investment partially had a significant effect on stock market value, while environmental management did not show a significant effect on stock market value. However, simultaneously, both have a significant effect on stock market value. This finding confirms that the market is starting to take sustainability into account in assessing company performance and prospects, especially when there is an allocation of funds as a tangible action for environmental activities. Therefore, companies are advised to not only fulfill regulations through PROPER, but also provide tangible evidence in the form of environmental investment in order to attract investor confidence and increase stock market value.]]>
