It is often noted that green criminology is interdisciplinary and as a result, lacks its own unique theory or any preferred theoretical approach. Moreover, significant portions of the green criminological literature are qualitative and descriptive, and those studies have generally not proposed a unique or unifying theory. Despite this general lack of a singular theory, some of the approaches noted above indicate certain theoretical preferences. For example, as noted, the political economic approach to green criminology develops explanations of green crime, victimization and environmental justice consistent with several existing strains of political economic analysis. Beirne’s approach takes an interdisciplinary view of theory with respect to various animal rights models and arguments. Clarke’s rational choice models of animal poaching and trafficking build on the rational choice tradition found within the criminological literature. To date, these different theoretical approaches have not been examined as competing explanations for green crime and justice, a situation that is found with respect to orthodox or traditional criminological theories of street crime.
