Particularly in emerging nations, corporate environmental criminality poses a serious threat to environmental justice, sustainable development, and legal responsibility. With a focus on corporate crime theory and green criminology, this study critically analyzes corporate environmental crime using an integrative framework that blends modern criminological viewpoints with Islamic criminal law (fiqh al-jināyah). This study examines how Islamic legal concepts, particularly the doctrine of maqāṣid al-sharī‘ah, can enhance current models of corporate criminal responsibility and environmental governance using a normative-analytical and conceptual approach. The results show that structural incentives, lax enforcement, and profit-driven rationalization tactics make traditional regulatory and penal measures ineffective at discouraging corporate environmental malfeasance. Islamic criminal law provides a revolutionary framework that places environmental conservation as both a legal requirement and a moral necessity because of its strong ethical orientation and comprehensive view of justice. With a focus on ecological balance (ḥifẓ al-bi’ah), property (ḥifẓ al-māl), and life preservation (ḥifẓ al-nafs), this study offers a value-based corporate accountability approach that goes beyond deterrence-oriented punishment and prioritizes prevention, restoration, and social responsibility. By broadening the doctrinal scope of Islamic criminal law to acknowledge corporate criminal culpability, this integrative approach makes a theoretical contribution. Practically, it informs regulatory enforcement and environmental policy change. The study presents an interdisciplinary paradigm that unites criminological analysis and religious legal reasoning, providing a strong basis for creating environmental governance systems that are just, moral, and sustainable, especially in developing nations and jurisdictions with a majority of Muslims.

Corruption remains a systemic challenge in Indonesia, particularly in the administration of government grant funding, undermining public trust, institutional integrity, and sustainable development. Despite the establishment of the Corruption Eradication Commission (Komisi Pemberantasan Korupsi, KPK) and other specialized bodies, law enforcement continues to face institutional, political, and cultural barriers. This study explores how Islamic criminal law can strengthen anti-corruption strategies by integrating empirical legal practices with normative religious principles. Using a normative-empirical socio-legal approach, the research combines case studies of KPK’s enforcement processes with doctrinal analysis of fiqh jināyah. Data were collected through legal document analysis, policy reviews, and qualitative evaluations of institutional reports and court rulings. Findings indicate that Islamic legal concepts such as khiyānah (breach of trust), ghulūl (misappropriation of public assets), amānah (trustworthiness), ʿadl (justice), and maṣlaḥah (public interest) provide a strong ethical foundation that complements positive law enforcement. While KPK has demonstrated effectiveness in investigation, prosecution, and prevention, its performance is constrained by political pressure, regulatory gaps, and limited resources. The study concludes that embedding Islamic ethical principles into governance, legal education, and public administration can enhance institutional accountability, reinforce preventive measures, and cultivate a culture of integrity. This normative convergence advances socio-legal pluralism and offers practical insights for value-based anti-corruption policy in Indonesia.
