This chapter provides an overview of critical green criminology. The generic title “green criminology” refers to a variety of approaches, theories and perspectives (White, 2011; White & Heckenberg, 2014; Beirne & South, 2007; Ruggiero & South, 2010; South & Brisman, 2013). However, the focus of this chapter is not on green criminology in general, but rather its critical versions.
