At its heart is the principle of prevention which imposes an obligation on states to exercise due care in the face of risks of environmental damage. This chapter presents prevention as a multifaceted norm that operates at multiple levels in order to best anticipate different types of risks. It analyses prevention from three different perspectives. First, it identifies its material scope by detailing the different categories of risks which are covered by prevention. Second, it looks at the temporal scope of prevention and highlights the multiple conceptions of the future found in the principle. Finally, it presents the potential beneficiaries of the preventive rationale to explain how it aims to shape the future of different audiences. The chapter concludes on the challenges brought about by the multifaceted nature of prevention.
