This study investigates the financial dynamics of 182 manufacturing companies listed on the Indonesia Stock Exchange from 2019 to 2022, focusing on the impact of environmental performance on firm value. Using a quantitative approach with SPSS for regression analysis, the research reveals that while capital structure and dividend policy do not significantly affect firm value, firm growth, profitability, and investment decisions have differential impacts. Environmental performance moderates the effect of growth and profitability on firm value but does not significantly influence relationships involving capital structure, dividend policy, or investment decisions. The study highlights the importance of sustainable practices in improving financial performance and firm value, especially during global crises like the COVID-19 pandemic. It contributes to financial analysis by incorporating environmental performance as a moderating factor. The findings suggest that environmental performance plays a crucial role in shaping firm value, particularly in the context of economic and environmental challenges. The research also emphasizes the need for companies to integrate environmental considerations into their decision-making processes to enhance long-term value creation. The study provides insights into how companies can improve their value by considering both financial and environmental factors in their strategies. The results indicate that firm growth has a positive impact on firm value, while profitability and investment decisions have mixed effects. Environmental performance is found to moderate the relationship between firm growth and profitability and firm value. The study underscores the importance of sustainable practices in corporate finance and the need for companies to adapt to environmental challenges.
