Green criminology is now an established subfield of criminology. Having emerged in the 1990s, green criminology has rapidly grown, particularly in the last 10 years. Scholarship remains rooted in the critical and radical traditions that inspired its creation and challenge the orthodoxy of most criminological scholarship. This means that research in green criminology does not stick within the confines of only what is deemed criminal by the state but also uncovers harmful and injurious behaviors, particularly of the powerful, such as states and corporations. These once-hidden harms are approached from an environmental justice perspective that exposes the injury and suffering of marginalized people and also to the environment itself (ecological justice) and to nonhumans (species justice). More recent iterations of green criminology feature culture in addition to political economic explanations of crimes and harms against the environment and other species. Both theories of green crimes criticize capitalist societies and the ongoing problems of commodification and excessive consumption. In addition, new contributions, particularly from the Global South, are challenging the hegemony of Western criminological and environmental discourses, offering new (to the West) insights into relationships with nature and with other people. These studies have the potential to shape new prevention strategies and intervention mechanisms to disrupt green crimes and harms. This is urgent as the magnitude of environmental degradation is increasing—ranging from the threat of climate change, the possible extinction of a million species in the near future, and the ubiquity of plastic pollution, to name just a few forms of environmental destruction that humans have been, and are, perpetrating against the Earth.
