This chapter looks at whether and how international organizations and criminal law can help us deal effectively with transnational environmental crimes and, more broadly, with environmental insecurity and injustice. It explores the question of whether the climate change justice agenda can benefit from the expanded pursuit of transnational environmental crime. The chapter asks whether international environmental law, refurbished, act as a mitigating factor in climate change. It concludes that while current international legal instruments can help spur additional action, by themselves, they will prove inadequate. Consequently, one idea proposed is a new international environmental court to deter all forms of ecocide.
