ABSTRACT
The link between international investment treaties and environmental protection has been the subject of many heated debates. There is little doubt that states have been responding to pressures imposed on them by both academics and civil society organisations, and that as a result investment treaty-practice has been evolving. This chapter provides an up-to-date review of these developments: It provides a critical analysis of the reforms of both procedural and substantive rules. Special attention is given to less explored elements (e.g. environmental impact assessments) as well as to novel and controversial legal instruments (e.g. investors’ obligations, use of Corporate Social Responsibility and more).
