In light of the expanding global environmental challenges, multinational corporations (MNCs) are often held accountable for their disproportionate role in environmental degradation. This study looks at how MNCs safeguard the environment and what factors lead to ecological dangers that are related with them. The production volumes of MNCs and their inclination to relocate pollution-intensive industries to developing countries are the specific subjects of the study. A few of the main obstacles that the study identifies to MNCs' environmental responsibility are the deficiency of the current international legal framework, the lack of harmonization of environmental legislation, and the tendency of developing countries' economic priorities to overlook strict environmental measures. To address these issues, the study recommends the following measures: the establishment of robust monitoring and accountability mechanisms; the direct imposition of practicable environmental liabilities; the strengthening of international judicial cooperation; and the clarification of judicial ambiguities regarding MNCs' legal responsibilities in the environmental sector. The paper uses a case study methodology to provide a comprehensive review of best practices and tactics for improving MNCs' environmental management. The findings underline the importance of governments working together to ensure that multinational firms' actions are consistent with environmental sustainability ideals.
