Commonly regarded as one of the world’s fastest-growing illicit businesses, transnational environmental crime is becoming increasingly orchestrated by organized criminal networks. This chapter examines the intersection of organized crime with environmental degradation, where illegal networks exploit governance gaps and technological infrastructure to engage in the trafficking of wildlife, timber, minerals, and hazardous waste. This chapter aims to elucidate the intricate relationships between these actors and environmental degradation, examining the socio-political, ecological, and economic consequences. To accomplish this goal, the author integrates global case studies, environmental crime documents, and recent publications from the United Nations Office on Drugs and Crime (UNODC), INTERPOL, and the United Nations Environment Programme (UNEP). Using comparative environmental criminology methods, the study examines the extent to which organized criminal groups have intensified their infiltration into local economies and compromised state institutions. The study also examines technological countermeasures to criminal resilience and international deterrence strategies targeting these enterprises, with a focus on new geospatial intelligence and AI-driven predictive analytics surveillance systems. The research results revealed an alarming phenomenon of international environmental crime. In 2023 alone, more than 4000 animal and plant species were seized in illegal trade in 162 countries, and in that year alone, crime profits from the exploitation of the environment surpassed USD 281 billion. The findings also reinforce a pattern of ecological devastation in areas most susceptible to governance gaps, particularly in the Global South, where illegal waste disposal and the excessive extraction of natural resources threaten biodiversity, public health, and well-being. The discussion situates these results within the context of environmental justice frameworks that highlight the inequitable distribution of harm to already vulnerable populations. It also analyzes the changing scope of mitigating environmental crimes, where collaboration among different agencies, more vigorous enforcement, and the use of new and sophisticated technologies create emerging strategies for responsibility and enforcement. Finally, this chapter emphasizes the need to reposition global approaches by integrating legal changes, innovation, and cooperative frameworks, which can help disrupt transnational organized crime, environmental damage, and the broader phenomenon of global environmental crime. These actions are crucial for maintaining ecological balance, promoting justice, and fostering a stable world.
